Infrared photoconduction at the diffusion length limit in hgte nanocrystal arrays

HIGHLIGHTS

  • who: Audrey Chu from the CNRS have published the Article: Infrared photoconduction at the diffusion length limit in HgTe nanocrystal arrays, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
  • what: The authors design and fabricate devices based on nanotrenches with inter-electrodes spacing matching the carrier diffusion length22. The authors demonstrate that the small size of the device shows a significant gain (>106), leading to the largest responsivity reported in HgTe NC films operated in the extended short-wave infrared. The authors demonstrate that specific detectivity D* as high as 1012 Jones is achieved (200 K . . .
