2022年9月30日 · VSSe can be efficiently activated for HER by doping As, Si, C, or Ge. A free energy of −0.022 eV has been realized by As doping, better than Pt. Searching electrocatalysts with excellent hydrogen evolution reaction (HER) performance is very important for developing clean hydrogen energy.

2020年7月6日 · The structural, electronic, and magnetic properties of VSSe, VSeTe, and VSTe monolayers in both 2H and 1T phases are investigated via first-principles calculations. The 2H phase is energetically favorable in VSSe and VSeTe, whereas the …

密度泛函理论 (DFT) 计算表明，在 VSSe 的 S 或 Se 位中掺杂 As 和 Si 原子以及在 VSSe 的 Se 位中掺杂 C 和 Ge 原子极大地促进了 VSSe 基面的 HER 性能，导致氢吸附自由能接近于零（即分别为-0.022、-0.040、0.066、0.065、-0.030、0.058 eV），优于 Pt 催化剂（-0.09 eV）。

2025年1月1日 · To adjust the spontaneous valley characters using the magnetic proximity effect, the 2H-VSSe/CrI 3 ferrovalley/ferromagnetic heterostructure is constructed. In this work, the electronic structure, magnetic and valley properties of 2H-VSSe/CrI 3 heterostructures with different configurations are studies systematically.

2015年8月12日 · 一个multivolage的设计在dc阶段的时候带上了sram。这个sram有两个power port，VDDCE和VDDPE。但只有一个ground port VSSE。 按照要求，两个power port实际是接上同样的电源。也没有power gating的问题。

2022年9月7日 · Using first-principles calculations, we investigated the magnetic and optical properties of monolayer 2H VSe2 and VSSe. We obtained a direct band gap of 1.04 eV in pristine 2H VSe2 and 1.05 eV for the Janus VSSe layer. Both systems displayed a …

2019年5月29日 · Herein, new ternary vanadium-based TMD, VSSe alloy single crystals were synthesized for the first time by agent-assisted chemical vapor transport and used as an excellent HER electrocatalyst due to the pure conductive phase and abundant active sites induced by ternary structures.

Akin to three dimensional (3D) multiferroics, two dimensional (2D) piezoelectric materials with intrinsic magnetic properties are promising applications in nanoscale spintronic devices. In this study, 2D magnetic transition metal dichalcogenides (VS2, VSe2, and Janus-VSSe) have been investigated by the first 2018 PCCP HOT Articles

CVT system for single-crystal growth of VS2, VSe2, VSSe-I and VSSe-V. Initially, the temperature of source zone (Zone 1: Vanadium, sulfur and/or selenide and transport agent) was kept at 920 ºC and that of growth zone (Zone 2) at 980 ºC to allow

2024年12月26日 · Here, a viscoelastic soft solid electrolyte (VSSE) strategy is presented that effectively balances Zn ion conduction and Zn anode stability. The VSSE is created by...
