  • Semiconductor nanowire photoelectric device
    Patent number: 10333013
    Abstract: A photoelectric semiconductor nanowire device and a method for manufacturing the same. The photoelectric semiconductor nanowire device includes a semiconductor nanowire doped with a dopant of a first conductivity type and including crystal semiconductor segments which include at least one porous semiconductor segment and are connected to opposite ends of the porous semiconductor segment. A first electrode and a second electrode respectively are disposed in the crystal semiconductor segments around the porous semiconductor segment to provide an electrical connection. The crystal semiconductor segment includes a crystal semiconductor, and the porous semiconductor segment includes a porous semiconductor. The semiconductor nanowire provides a current according to the intensity of an external light when the external light is irradiated to the porous semiconductor segment.
