Electronic levels

e_?0

Definition

Charge level at 0 K, measured from the valence band edge.

Interrogation mark (?) is used to indicate the particle for which the parameter is defined, for instance, e_AsVP0 is the charge level at 0 K for positive arsenic-vacancy [1].

• If the particle indicated by interrogation mark (?) is positive, with charge "j", e_?0 denotes the charge level (at 0 K) for the transition between charge states "j-1" and "j". For instance, e_AsVP0 is the charge level for the transition between AsV and AsV⁺, and can be also denoted by e_AsV(+,0).

• If the particle indicated by interrogation mark (?) is negative, with charge "j", e_?0 denotes the charge level (at 0 K) for the transition between charge states "j" and "j+1". For instance, e_VMM0 is the charge level for the transition between V^{- -} and V^-, and can be also denoted by e_AsV(-,- -).

Comments

1. According to this notation, if the particle is neutral, this parameter is not defined and it would be ignored if found in the DDP file.

2. When the Fermi level, e_F, is at e(j-1,j), the probability of "j-1" and "j" states is the same.

3. e_?0 sets the relation among the binding energies of different charge states of an impurity-"native defect" pair.
