Abstract
We have fabricated a phototransistor based on multilayer MoTe2 and investigated its optical response. Under dark, the transistor exhibits ambipolar behavior with an on-off ratio of around 1000 for hole transport. The photocurrent of the transistor is modulated by illuminating the transistor with laser light and varying its power and the electrostatic gate voltage. We investigated the correlation between the laser power and the on/off ratio, photocurrent, and maximum current of the device. Finally, we analyzed the regions in the transfer curve that are least sensitive and most sensitive to incident laser light.
