Matrix context

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

D.11 × C.36 · Incident radiation flux × Photodiffusivefamily: Photodiffusive

Steps

  1. 01
    radiative → electrical · loss to thermal
    • 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
    solid · semiconductor required · illumination required

  3. 03
    electrical → electrical · loss to thermal
    • electrodes on the charged surfaces connected through a load
