Phototransistors: High‐Detectivity Multilayer MoS₂ Phototransistors with Spectral Response from Ultraviolet to Infrared (Adv. Mater. 43/2012)

Sunkook Kim, Jinsoo Joo, and co-workers demonstrate on page 5832 phototransistors based on multilayer MoS₂ crystals with a wider spectral response and higher photoresponsivity than single-layer MoS₂ phototransistors. These multilayer MoS₂ phototransistors also exhibit high room-temperature mobilities, near-ideal subthreshold swings, low operating gate biases, and negligible shifts in the threshold voltages during illumination.
