和提高载流子迁移率的方法之一,该方法在改良相似材料MoS2中成果显著.掺杂不仅可以改变材料的载流子,还能够推动材料由半导体向金属,半金属转变.实际上,掺杂在改进2H-WSe2和单层WSe2的电磁学性质中已初见成效,但对过渡金属和非金属掺杂的机理仍需要深入研究.尤其是近年来阴阳离子共掺的方法开始盛行,共掺WSe2的课题也...
Herein, the anisotropic carrier mobility from 2H WSe2is reported for the first time, where the anisotropic degree of carrier mobility spans from 0.16 to 0.95 for various WSe2field effect transistors under a gate voltage of -60V. Phonon scattering, impurity ions scattering, and defect scattering ...
In the present study, we performed CD-ARPES on 2H-WSe 2 with the crystal mirror plane taken as the experimental mirror plane. Within such an experimental constraint, two experimental geometries are possible for CD-ARPES. The Berry curvature distributions for the two geometries are expected to be...
本文中,作者利用角度分辨光发射技术,研究2H-WSe2中隐藏的贝里曲率。结果显示,提取的谷和谷的圆二色性(circular dichroism, CD)信号几乎相同, 但由谷指数决定的符号却相反。同时,观察到两个自旋分裂带的符号是相同的,表明其是独立于自旋状态的。为了验证该结果是否真的代表层内隐含的贝里曲率,作者采用紧束缚密度...
The A exciton series in the liquid-nitrogen-temperature epsilon 2 spectra of 2H-WSe2 and 3R-WS2, derived from Kramers-Kronig analyses of normal-incidence, basal-plane reflectivity spectra, have been fitted to a Lorentzian oscillator model. It has been found that the energy levels and oscillator...
The layered structure of 2H-WSe2is grown over the rGO sheets.The SC of WSe2@rGO is nearly two times greater compared to pure WSe2.WSe2@rGO electrode shows improved cycling stability compared to pure WSe2electrode.The ASC (WSe2@rGO//AC) device shows energy density 51.5 WhKg1at power de...
