Nonuniform electric field in quantum well diodes

Not Accessible

Your library or personal account may give you access

Abstract

Unintentional doping is known to give rise to nonuniform electric fields in PIN diodes,1 which can broaden optical absorption features and mask subtle electric-field-dependent effects. We used low-temperature photocurrent spectroscopy and photoluminescence as complementary methods for mapping the field profile within the intrinsic region of a quantum-well diode.
