Preparation and Luminescent Properties of ZnTe-Cd_1-xMn_xTe_1-ySe_yHeterojunction

Abstract

ZnTe-Cd1-xMnxTe1-ySey heterojunctions were prepared by vaportransport epitaxy of ZnTe on In-doped Cd1-xMnxTe1-ySey (x = 0.05, y = 0.03) single crystalline substrate in vacuum. At temperatures lower than 120 K the infrared and red electroluminescence were observed from the ZnTe-Cd1-xMnxTe1-ySey diode with forward current density in the range 0.003-4.0 A/cm2 .

The Catalytic Valorization of Lignin for the Production of Renewable Chemicals

“…Benzofuran (Figure , 68 ) has been used as a common probe molecule to evaluate catalyst performance in hydrodeoxygenation reactions, and various studies using Ni−Mo or Co−Mo catalysts have been reported, with the former being more active for this substrate. − As indicated above, the reduced benzofuran derivative, 2,3-dihydrobenzofuran, resembles some of the cyclic ethers found in lignin and is therefore studied as a model compound of this linkage. Different hydrodeoxygenation routes have been suggested depending on the catalyst and conditions used, but ethylcyclohexane is commonly obtained as the major product.…”
