Here, we show that for different alloy compositions of WS 2(1 x ) Se 2 x this trend may be significantly affected by the alloy content and we demonstrate that the sample with the highest Se ratio presents a strongly reduced effect. The highest micro-PL intensity is found for bilayer WS ...
有鉴于此,近日,韩国高丽大学Chul-Ho Lee和Donghun Lee(共同通讯作者)等报道了使用金属有机化学气相沉积技术,实现了具有连续可调带隙的成分调制WS2xSe2(1-x)合金的晶圆级均匀生长。良好优化的生长可以在整个晶圆上实现具有优良均匀性的单层薄膜。通过改变金属-有机前驱体的流动速率,WS2xSe2(1-x)合金中的取代原子(...
More importantly, through optimizing the growth conditions, ternary WS2(1–x)Se2x nanotubes were synthesized and the composition of S and Se can be systematically controlled. The as-grown WS2(1–x)Se2x nanotubes on carbon fibers, assembled as a working electrode, revealing low overpotential, ...
