A??1_?

Definition

Parameters used to calculate carrier-related band gap narrowing (see band gap narrowing).

Interrogation marks (?) are used to indicate the use of this set of parameters in different expressions. For instance: Acp1_3 is used for the conduction band (c) in a p-semiconductor (p); last value (3) is used used as a denominator in exponents in the band gap calculation.

Units

Dimensionless.
