Raman spectroscopy and electrical measurements are performed on sputtered GexSe1?x thin films to identify link bond presence behaviour.

• Stretched exponential function fits kinetics of photoinduced effects in GeSe2 Parameters βand τ depend on properties light and sample prehistory Values β are linked with mechanisms photostructural transformations Thermally evaporated chalcogenide glass thin films known to be highly photosensitive revealing both metastable transient changes optical transmission at the fundamental absorption ed...

In a transformer, the insulation materials will produce different dissolved gases due to various faults in operation of which C2H2, CH4, and H2 are main gases. this study, adsorption characteristics above three on SnO2–GeSe monolayer surface were discussed analyzed based density functional theory. The energy, transfer charge, geometric structure parameters, electronic states, local function, ch...

2D Ferroelectric materials are promising for designing low-dimensional memory devices. Here, we explore strain tunable ferroelectric properties of group-IV monochalcogenides MX (M=Ge, Sn; X=S, Se) and their potential application in lateral field tunnel junction We find that these monolayers have in-plane ferroelectricity, with parameters being on par other known materials. Amongst SnSe, SnS, Ge...
