Electrical and optical evidence of resonant tunneling of holes in an n+i n+ double-barrier diode structure under illumination

Abstract
Using low‐temperature photocurrent, steady‐state and time‐resolved photoluminescence, we have shown the importance of hole transport in the optical properties of n+in+ double‐barrier diodes under operation. We have also seen evidence of resonant tunneling of minority holes in such an illuminated double‐barrier diode.
