Abstract

In this work, we fabricated and measured a bilayer MoS2 devices based on nanopore structure. The bilayer MoS2 films were synthesized and placed on top of the nanopore. The gold metal is then evaporated and contacted to top and bottom of MoS2 film to form electrodes for electronic measurement. The asymmetric Au/MoS2/Au devices exhibit current-voltage rectification which is attributed to photovoltaic properties. The photo-response of a nanopore based bilayer MoS2 devices is investigated which shows short circuit current as well as open circuit voltage under illumination. It is also found that the photogain of devices is calculated in the range of 105 and switching behavior with light is stable and reproducible. These characteristics make atomic layered MoS2 device to be great potential for application in electronics and optoelectronics.
