Thermodynamic basis of the concept of "recombination resistances"

TL;DR

This paper explores the thermodynamic foundations of the 'recombination resistance' concept, framing it within irreversible thermodynamics to relate affinities and recombination rates to a thermodynamic Ohm law.

Contribution

It provides a thermodynamic interpretation of recombination resistance, linking it to entropy production and establishing a formal analogy with electrical resistance.

Findings

Recombination affinities act as voltages in a thermodynamic Ohm law.

Net recombination rates are analogous to electrical currents.

Dissipated power relates to entropy production in recombination processes.

Abstract

The concept of "recombination resistance" introduced by Shockley and Read (Phys. Rev. 87, 835 (1952)) is discussed within the framework of the thermodynamics of irreversible processes ruled by the principle of the minimum rate of entropy production. It is shown that the affinities of recombination processes represent "voltages" in a thermodynamic Ohm-like law where the net rates of recombinations represent the "currents". The quantities thus found allow for the definition of the "dissipated power" which is to be related to the rate of entropy production of the recombination processes dealt with.
