Surface and interfaces properties

Recombination length

Recombination length is defined as:

Where:

• λ is the jump distance.

• p is the probability of being captured at the surface.

The probability affects emission frequency of single neutral native defects. Thus, the recombination length does not affect the equilibrium concentration, C*.

Solubility

Let's assume a negative dopant, A^-. Its solubility in intrinsic conditions (e_F = e_i) is given as:

Where:

• [A]_max^extrinsic is the maximum concentration for extrinsic conditions, that can be measured this way:

• e_F is the Fermi level.
• e_i is the intrinsic level.
• See symbol list.
