Spontaneous flexoelectricity and band engineering in MS<sub>2</sub> (M = Mo, W) nanotubes
Jiansheng Dong, Huamin Hu, Hai Li, Gang Ouyang
Abstract
Flexoelectricity in double-wall TMD nanotubes can lead to a straddling-to-staggered bandgap transition with increasing tube diameter, showing how different diameters correspond to a variety of applications in optoelectronic devices.
