Incident radiation flux —drives→ Photo-Dember effect

Conditions

• non-uniform above-gap illumination of a semiconductor with a large electron–hole mobility difference (InAs, InSb); pulsed excitation gives the transient current used for terahertz emission, steady illumination a Dember photovoltage
