Abstract

Phototransistors based on multilayer MoS2 crystals are demonstrated with a wider spectral response and higher photoresponsivity than single-layer MoS2 phototransistors. Multilayer MoS2 phototransistors further exhibit high room temperature mobilities (>70 cm2V−1s−1), near-ideal subthreshold swings (∼70 mV decade−1), low operating gate biases (
