At present, non-equilibrium thermodynamics is an important theory and method for studying the phenomenon of small scales. In this work, by studying the temperature changes of PN junctions under different voltage conditions and doping concentrations, the micro-scale semiconductor materials PN junctions in non-equilibrium thermodynamics and thermal phenomena are researched. It is found that under the effect of lower voltage, the temperature of the PN junction will first decrease and then increase, and as the voltage increases, this phenomenon will gradually disappear. This shows that under certain voltage conditions, the phenomenon of unbalanced junction temperature of the PN junction exists, which will provide a huge impetus for the development of the reliability of solar cells, light-emitting diodes, high-frequency devices, sensors and measurement methods.
