Solution processed vertical p-channel thin film transistors using copper(i) thiocyanate

Here, we present a strategy for the realization of p-channel inorganic thin film transistors (TFTs) based on vertically stacked contacts and a copper(i) thiocyanate (CuSCN) semiconductor. The CuSCN semiconductor was generated by a simple low-temperature (ca.100 C) solution-based process. Utilizing the vertical architecture, channel length was determined by the thickness of the CuSCN film. This readily endows transistors with ultrashort channel lengths (<700 nm) to afford delivering drain current greatly exceeding that of conventional planar TFTs. Thus, high normalized transconductance of 0.84 S m?1and current density of 248 mA cm?2can be achieved for CuSCN-based vertical TFTs. To further improve the device's performance, we doped SnCl2into the semiconductor film. By doping SnCl2into CuSCN, shallow acceptor states that could induce additional holes were generated above the valence band maximum. The SnCl2-doped TFTs showed enlarged transconductance and current density values of 1.8 S m?1and 541 mA cm?2, respectively, which are comparable with those of other high performance vertical transistors. The p-channel inorganic TFTs developed in this study can open up exciting opportunities in complementary circuits, display switching, and flexible electronics.

Donor?Acceptor-Conjugated Polymer for High-Performance Organic Field-Effect Transistors: A Progress Report

Polymeric semiconductors have demonstrated great potential in the mass production of low-cost, lightweight, flexible, and stretchable electronic devices, making them very attractive for commercial applications. Over the past three decades, remarkable progress has been made in donor?acceptor (D?A) polymer-based field-effect transistors, with their charge-carrier mobility exceeding 10 cm2 V?1 s?1. Numerous molecular designs of D?A polymers have emerged and evolved along with progress in understanding the charge transport physics behind their high mobility. In this review, the current understanding of charge transport in polymeric semiconductors is covered along with significant features observed in high-mobility D?A polymers, with a particular focus on polymeric microstructures. Subsequently, emerging molecular designs with further prospective improvements in charge-carrier mobility are described. Moreover, the current issues and outlook for future generations of polymeric semiconductors are discussed.

Screen printed Pb3O4 films and their application to photoresponsive and photoelectrochemical devices

A new and simple procedure for the deposition of lead (II, IV) oxide films by screen printing was developed. In contrast to conventional electrochemical methods, films can be also deposited on non-conductive substrates without any specific dimensional restriction, being the only requirement the thermal stability of the substrate in air up to 500 C to allow for the calcination of the screen printing paste and sintering of the film. In this study, films were exploited for the preparation of both photoresponsive devices and photoelectrochemical cell photoanodes. In both cases, screen printing was performed on FTO (Fluorine-Tin Oxide glass) substrates. The photoresponsive devices were tested with I-V curves in dark and under simulated solar light with different irradiation levels. Responses were evaluated at different voltage biases and under light pulses of different durations. Photoelectrochemical cells were tested by current density-voltage (J-V) curves under air mass (AM) 1.5 G illumination, incident photon-to-current efficiency (IPCE) measurements, and electrochemical impedance spectroscopy.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1111-67-7 is helpful to your research. Electric Literature of 1111-67-7

About a synthetic saliva for in vitro studies

Numerous artificial salivas have been used during studies in odontology. These salivas have compositions, which are more or less the same as that of natural saliva. In this article, we are presenting a discussion about the various media described in the related literature. A review of nearly 60 artificial salivas was carried out to clarify the role of some of the compounds most frequently met in the proposed formulae. The study focused on the buffer effect, the role played by CO2 gas and the presence of calcium ions, hydrogenocarbonates, hydrogenophosphates and thiocyanates. The SAGF medium, which we proposed some years ago, was used as a reference and some in vitro behavioral tests of dental biomaterials were studied in a comparative way. Using the SAGF medium allowed us to specify the mode of fluoride ions release from glass ionomer cements and the corrosion behavior of the dental amalgams.

Mechanistic studies of copper thin-film growth from CuI and CuII beta-diketonates

The kinetics and mechanism of copper film growth from the reactions of bis(acetylacetonato)copper(II), bis(hexafluoroacetylacetonato)copper(II), and (vinyltrimethylsilane)(hexafluoroacetylacetonato)copper(I) (Cu(hfac)(vtms)) with copper single crystal surfaces were investigated. Experiments were performed using vibrational spectroscopy (reflection infrared and high-resolution electron energy loss spectroscopies) as well as mass spectrometry (temperature-programmed desorption and integrated desorption mass spectrometries). Both ligand desorption and dissociation were observed upon pyrolysis of these molecules under ultra-high-vacuum conditions. We demonstrate that adsorbed beta-diketonate ligands decompose in a stepwise fashion at temperatures above ?375 K to yield adsorbed CF3 and ketenylidene (?C-C?O) intermediates. These further decompose above ?500 K to leave surface carbon, a major contaminant in copper films grown from CuII beta-diketonates. Clean films can be grown from the pyrolysis of Cu(hfac)(vtms) at pressures above 10-5 Torr, however. The implications of our results relative to the mechanism of copper film growth at elevated pressures are also discussed.

Effect of surface treatment of the support on co oxidation over carbon-supported Wacker-type catalysts

The impact of surface treatment of the support on the oxidation of CO over carbon-supported Wacker-type catalyts was studied. This study focused on the effect of the chemical properties of activated carbon on CO oxidation over supported PdCl2-CuCl2 and PdCl2-CuCl2-Cu(NO)32 catalyts. The surface of active carbon used to prepare supported Wacker-type catalysts was enriched with carboxylic acid and carbonyl groups by pretreating with HNO3 or adding Cu(NO3)2 as a supplementary copper precursor. These surface groups improved the hydrophilicity and facilitated the formation of an active copper phase (Cu2Cl(OH)3). The effects were stronger, particularly on the formation of Cu2Cl(OH)3, when Cu(NO3)2 was combined with CuCl2 as catalyst precursors. The acceleration of CO oxidation can be attributed to the formation of the active copper phase and the improved hydrophilicity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1317-39-1, you can also check out more blogs aboutRelated Products of 1317-39-1

Evaluation of Small Molecules as Front Cell Donor Materials for High-Efficiency Tandem Solar Cells

Three small molecules (SMs) (DR3TSBDT, DR3TBDTT, and DRBDT-TT) were used as the front cell donor materials for highly efficient tandem OSCs which ensured both high open-circuit voltages and current density. The SM:PC71BM single-junction cell was fabricated with a structure of ITO/CuSCN/SM:PC71BM/ETL-1/Al. A thin layer of CuSCN processed from dimethyl sulfi de solution was spin-cast on top of precleaned ITO substrates and annealed in air at 120C for 10 minutes. or DR3TBDTT:PC71BM, chloroform was used for solvent vapor annealing. The tandem OSCs based on DR3TBDTT and DRBDT-TT also showed high PCEs of 10.73% and 10.43%, respectively. However, the overall open-circuit voltages is a little lower than the sum of open-circuit voltages of the subcells, suggesting a suboptimal contact at active layer/intermediate layer interface. A higher PCE would be obtained if the ICLs would be further optimized. All these demonstrate that the monodisperse SMs could perform as promising donor materials for high-performance tandem solar cells.

Organocatalyzed Asymmetric alpha-Thiocyanation of Oxindoles: Synthesis of Chiral Tertiary 3-Thiocyanatoxindoles

An enantioselective thiocyanation of oxindoles has been developed for the first time using a bifunctional cinchona-derived organo-catalyst and N-thiocyanatophthalimide as the electrophilic thiocyanation source in the presence of 2-naphthol as the additive. Various enantioenriched 3,3?-disubstituted oxindoles with SCN-containing quaternary carbon stereocenters were synthesized under mild conditions in high yields (up to 99%) and good enantioselectivities (up to 6:94 er).
