Homogeneous quasi-chemical reactions in the solid phase

Homogeneous quasi-chemical reactions in the solid phase 

These reactions take place within the solid phase. We can distinguish four categories of homogeneous reactions electron reaction, reactions creating disorders (and conversely annihilating disorders), ionization reactions and addition reactions. 

An electron reaction is the recombination of the free electrons and electron holes, which is written as  

We will take the example of the creation of the Schottky disorder in a binary solid, which is written as  

This reaction creates a new building unit of the crystal, whose dimensions therefore increase (conservation of the ratio of sites).
