Optical Signature of Bias-Induced Carrier Injection in a WSe2/MoS2 Heterostructure Diode

Yasuyuki Hirata, Hibiki Kinpara, Shinya Ohno +1

We investigate the bias-dependent photoluminescence (PL) response of a WSe${}_2$/MoS${}_2$ heterostructure diode. Under forward bias, trion-related emission in WSe${}_2$ is markedly enha…
