Ultrafast charge transfer in atomically thin MoS2/WS2 heterostructures
Xiaoping Hong,Jonghwan Kim,Su-Fei Shi,Yu Zhang,Chenhao Jin,Yinghui Sun,Sefaattin Tongay,Junqiao Wu,Yanfeng Zhang,Feng Wang +9 more
TL;DR: It is shown that hole transfer from the MoS2 layer to the WS2 layer takes place within 50 fs after optical excitation, a remarkable rate for van der Waals coupled two-dimensional layers, which can enable novel two- dimensional devices for optoelectronics and light harvesting.

Strain-Modulated Bandgap and Piezo-Resistive Effect in Black Phosphorus Field-Effect Transistors
Zuocheng Zhang,Likai Li,Jason Horng,Naizhou Wang,Fangyuan Yang,Yijun Yu,Yu Zhang,Guorui Chen,Kenji Watanabe,Takashi Taniguchi,Xianhui Chen,Feng Wang,Feng Wang,Yuanbo Zhang +13 more
TL;DR: The strain-modulated bandgap significantly alters the density of thermally activated carriers and opens up opportunities for future development of electromechanical transducers based on black phosphorus, and an ultrasensitive strain gauge constructed from black phosphorus thin crystals are demonstrated.
