Sunkook Kim, Jinsoo Joo, and co‐workers demonstrate on page 5832 phototransistors based on multilayer MoS 2 crystals with a wider spectral response and higher photoresponsivity than single‐layer MoS 2 phototransistors. These multilayer MoS 2 phototransistors also exhibit high room‐temperature mobilities, near‐ideal subthreshold swings, low operating gate biases, and negligible shifts in the threshold voltages during illumination.
