Electrostatically control interfacial states for stackable electronics

POSTER

Abstract

Semiconducting monolayer of transition metal dichalcogenides (TMD) is ideal fundamental unit for stackable electronics because of its excellent optoelectronic properties. However, further applications are hindered with various issues from trap states of the monolayers. Here we develop a method to effectively engineer trap states of the monolayer MoS2 for excellent optoelectronic performances, including ultrahigh photoresponsivity (R) of 10²~10⁴ A/W, high sensitivity (D*) of 10¹¹~10¹² Jones and large absorbance. A scalable image sensor array of CVD-grown MoS2 monolayer is demonstrated.
