Anisotropic photoluminescence of nonpolar ZnO epilayers and ZnO/Zn1 −xMgxO multiple quantum wells grown on LiGaO2 substrate
Yan, Tao; Trinkler, Laima E.; Korsaks, Valdis; Lu, Cheng Ying James; Berziņa, Baiba; Chang, Liuwen; Chou, Mitch Ming Chi; Ploog, K. H. (OSA - The Optical Society, 2020)The temperature-dependent polarized photoluminescence spectra of nonpolar ZnO samples were investigated by 263 nm laser. The degree of polarization (DOP) of m-plane quantum wells changes from 76% at 10 K to 40% at 300 K, ... -

Zn (Formula presented.) O and wurtzite Zn (Formula presented.) Mg (Formula presented.) O with the concentration of Zn and Mg varying ... -
Influence of Stress on Electronic and Optical Properties of Rocksalt and Wurtzite MgO–ZnO Nanocomposites with Varying Concentrations of Magnesium and Zinc
Lin, Yin-Pai; Piskunov, Sergei; Trinkler, Laima; Chou, Mitch Ming-Chi; Chang, Liuwen (MDPI, 2022)The structural, electronic and optical properties of stressed MgO–ZnO nanocomposite alloys with concentrations of Zn and Mg varying from 0.125 to 0.875 were studied using ab initio simulations. Two crystal structures are ... -
Luminescence Properties of Epitaxial Cu2O Thin Films Electrodeposited on Metallic Substrates and Cu2O Single Crystals
Trinkler, Laima; Dai, Dajin; Chang, Liuwen; Chou, Mitch Ming-Chi; Wu, Tzu-Ying; Gabrusenoks, Jevgenijs; Nilova, Dace; Ruska, Rihards; Berzina, Baiba; Nedzinskas, Ramunas (MDPI, 2023)The luminescent properties of epitaxial Cu2O thin films were studied in 10–300 K temperature range and compared with the luminescent properties of Cu2O single crystals. Cu2O thin films were deposited epitaxially via the ... -
