Strain wave pathway to semiconductor-to-metal transition revealed by time-resolved X-ray powder diffraction

Nature Communications, 2021
Ultrafast control of materials draws interest. Here, the authors extend X-ray powder diffraction to the femtosecond timescale to follow the photo-induced semiconductor to metal transition in titanium pentaoxide, observing a phase front that moves at the ...

Band structure engineering and transport properties of graphene/BN van der Waals heterostructures

Results in Physics, 2023
It is an important topic in spintronics to find regulable half-metallic materials. In this work, by using density functional theory and nonequilibrium Green’s functional method, we find that the van der Waals heterostructures formed by zigzag-edged boron

Strain effect in epitaxial VO2 thin films grown on sapphire substrates using SnO2 buffer layers

AIP Advances, 2017
Epitaxial VO2/SnO2 thin film heterostructures were deposited on m-cut sapphire substrates via pulsed laser deposition. By adjusting SnO2 (150 nm) growth conditions, we are able to control the interfacial strain between the VO2 film and SnO2 buffer layer ...
