We report, for the first time, the use of a single step deposition of semiconductor channel layer to simultaneously achieve both n- and p-type transport in transparent oxide thin film transistors (TFTs). This effect is achieved by controlling the concentration of hydroxyl groups (OH-groups) in the underlying gate dielectrics. The semiconducting tin oxide layer was deposited at room temperature,...

Cr3Al shows semiconducting behavior that has not been explained previously. We used density functional theory calculations, performed at the Cornell NanoScale Facility to study the effect of chemical ordering and magnetism on the semiconducting behavior. The calculations show that the proposed chemically ordered Cr3Al structure in the Cr1-xAlx phase diagram is the lowest energy structure of tho...

The industrial production of alkyl tin derivatives has increased rapidly in recent years, but little is known about the hazards to man which may exist in the handling of these substances. Interest in the matter has been sharpened by the catastrophic results of a therapeutic trial of one of the group, diethyl tin di-iodide, in the treatment of furunculosis. The compound was given orally and caus...

Organometallic compounds are widely used in almost all sectors of industry. as a result of emissions from natural and anthropogenic sources they are released to the environment, where they undergo a variety of conversions and interactions. some organometallic compounds exhibit high toxicity. organometallic compounds of mercury, tin, lead, selenium and arsenic are among the most common and hazar...

A series of new complexes of a general motif [R2E(μ-N,S)2TM-L] (E: metalloid group 14 element; TM: group 10 metal; R: Cl, Ph, pyS, OH, (N,N,O)-chelating ligands; N,S: 1-methylimidazole-2-thiolate (methimazolyl, mt(-)), pyridine-2-thiolate (pyS(-)); L: PPh3, PCy3, pyS) was synthesised and characterised by single-crystal X-ray diffraction, multi-nuclear NMR spectroscopy ((1)H, (13)C, (31)P, (119)...

Speciation, identification of the chemical states of elements in the environment, is indispensable in determining the environmental behavior, bioavailability, and the influence of elements on the quality of the environment. For speciation, X-ray absorption fine structure (XAFS) is a powerful tool, because it is a direct method by which we can avoid the change of the chemical state of target ele...

This work is a continuation of earlier research concerning the influence of tin compounds on the dynamic properties of liposome membranes produced with lecithin hen egg yolks (EYL). The experiments were carried out at room temperature (about 25 degrees C). Four tin compounds were chosen, including three organic ones, (CH3)4Sn, (C2H5)4Sn and (C3H7)3SnCl, and one inorganic, SnCl2. The investigate...
