The phototransistors utilizing hybrid MoS2


The phototransistors utilizing hybrid MoS2/PbS QDs were fabricated by Pak et al.. The PbS QDs were surface modified with n-type tetrabutylammonium iodide (TBAI) and p-type 1,2-ethanedithiol (EDT) ligands to develop p–n junctions. The MoS2/PbS-TBAI/PbS-EDT hybrid device showed a photoresponsivity of 5700 ± 71.2 A W−1 for a single-junction device and 6120 ± 96.9 A W−1 for a double-junction device at an incident laser power of 20 pW. The photocurrent rise time of 40 ms for the single-junction device was reduced to 950 μs for the double-junction device. The efficient charge transfer occurring in the MoS2/PbS QD hybrid photodetector yielded a maximum photoresponsivity of 5.4 × 104 A W−1 and a 1 × 1011 Jones detective. High photoresponsivity of 2570 A W−1 and detectivity of 2.2 × 1012 Jones at 635 nm in a few-layer MoS2 photodetector has been demonstrated under zero gate voltage with the use of a poly(vinylidene fluoride-tetrafluoroethylene) [P(VDF-TrFE)] ferroelectric polymer gate. This MoS2/P(VDF-TrFE) hybrid photodetector also showed photodetection over the 0.85 μm to 1.55 μm spectral region and excellent stability over 90 000 repeated cycles of operation.
