Direct Recombination
Use the Direct Recombination to set the recombination rate in direct band-gap semiconductor materials such as gallium arsenide. Select this option from the Generation–Recombination submenu.
The recombination rate for both electrons and holes is set using the following equation:
with
where γn and γp are the electron and hole degeneracy factors, Nc,0 and Nv,0 are the effective densities of states for the conduction and valence band, Eg is the band-gap and ΔEg the band-gap narrowing (SI unit: V).
Direct Recombination
The default Direct recombination factor C (SI unit: m3/s) is taken From material. For User defined enter a value in the text field. The default value is 0 m3/s.
