We investigated the electrical and optoelectronic characteristics of ambipolar WSe<sub>2</sub> field-effect transistors (FETs) via facile p-doping process during the thermal annealing in ambient. Through this annealing, the oxygen molecules were successfully doped into the WSe<sub>2</sub> surface, which ensured higher p-type conductivity and the shift of the transfer curve to the positive gate voltage direction. Besides, considerably improved photoswitching response characteristics of ambipolar ...[more]
