Abstract

We  study  nanowire  silicon  pin  and  pn-junctions  at  room  and  low  temperature.  Photovoltaic  effects  are  observed  for both devices at room temperature. At low temperature, nanowire pn-junction devices show their ability to detect single photon. This ability was not been observed for pin devices. Phosphorus-boron dopant cluster in the depletion region is considered  to  have  the  main  role  for  single-photon  detection  capability.  Fundamental  mechanism  of  dopant-based single-photon detection in nanowire pn-junction is described in details.
