TL;DR: In this article, a simple, low-cost and flexible hybrid cell that converts individually or simultaneously low-frequency mechanical energy and photon energy into electricity using piezoelectric zinc oxide (ZnO) in conjunction with organic solar cell design is presented.
Journal ArticleDOI
Thickness-dependent electron mobility of single and few-layer MoS2 thin-film transistors
TL;DR: In this article, the authors investigated the dependence of electron mobility on the thickness of MoS2 nanosheets by fabricating bottom-gate single and few-layer thin-film transistors with SiO2 gate dielectrics and Au electrodes.
Journal ArticleDOI
Enhanced carrier mobility of multilayer MoS2 thin-film transistors by Al2O3 encapsulation
TL;DR: In this article, the effect of Al2O3 encapsulation on the carrier mobility and contact resistance of multilayer MoS2 thin-film transistors was investigated by statistically investigating 70 devices with SiO2 bottomgate dielectric.
