Surface Control of Doping in Self-Doped Nanocrystals [PDF]

ACS Applied Materials & Interfaces, 2016
Self-doped nanocrystals raise great interest for infrared (IR) optoelectronics because their optical properties span from near to far IR. However, their integration for photodetection requires a fine understanding of the origin of their doping and also a way to control the magnitude of the doping.
