In this paper, a multilayer ReS2 p-n homojunction is fabricated on an oxidized Si substrate, and its photoemission under a forward bias and its photodetection under a reverse bias are reported for the first time. Au nanoparticles were used to make lateral p-n homojunctions. The device shows room temperature photoemission in the IR range, and in the photodetector mode, it shows a 0.41A/W responsivity under illumination by a 660nm red laser.
