External controlling the phase transition behavior of vanadium dioxide is important to realize its practical applications as energy-efficient electronic devices. Because relatively high temperature 68 °C, central challenge for VO2-based electronics, lies in finding an energy efficient way, modulate a reversible and reproducible manner. In this work, we report experimental realization p–n heterojunctions by growing VO2 film on p-type GaN substrate. By adding bias voltage junction,...
As a typical strong correlation material, vanadium dioxide (VO2) has attracted wide interest due to its particular metal–insulator transition (MIT) property. However, the relatively high critical temperature (Tc) of ~68 °C seriously hinders practical applications. Thus modulating phase process and decreasing Tc close room have been hot topics for VO2 study. In current work, we conducted multi-approach strategy control films, including interfacial tensile/compressive strain oxygen vacancies....
Insulator to metal phase transitions driven by external electric field are one of the hottest topics in correlated oxide study. While this triggered phenomena always mixes switching effect and joule thermal together, which difficult clarify intrinsic mechanism. In paper, we investigate dynamical process voltage-triggered metal-insulator transition (MIT) a VO2 crystal film observe temperature dependence threshold voltages delay times, can be explained quite well based on straightforward...
Exploration of exotic quantum physics in magnetic systems reduced dimensionality is among the central themes condensed matter physics. Here we investigate nature couplings, topological excitations, and critical phenomena monolayer $\mathrm{MnPS}{\mathrm{e}}_{3}$, a representative two-dimensional antiferromagnet. We first establish, based on first-principles calculations, that $\mathrm{S}=5/2\phantom{\rule{4pt}{0ex}}\mathrm{M}{\mathrm{n}}^{2+}$ ions possess single-ion anisotropy, favoring...
