Popis:	The nonuniform rate of creation of Joule heat due to variations in the electrical conductivity around dislocations in III‐V compounds gives rise to variations in the temperature around these dislocations. The general equations and boundary conditions for this temperature distribution are derived for any III‐V compound. The specific temperature distributions around 60° and edge dislocations in n‐type GaSb are calculated. It is found that the contribution of the dislocations to the temperature becomes significant within 500 A from the core, while the gradient of temperature reaches significant values at even greater distances.
