SUMMARY
The depletion region in a PN junction decreases with increasing temperature due to the temperature dependence of the Fermi energy levels in the p-type and n-type semiconductors. As temperature rises, the increased thermal energy allows more charge carriers to be generated, effectively reducing the width of the depletion region. Consequently, this reduction in depletion width leads to an increase in junction capacitance when the junction is reverse biased. The relationship between temperature and junction capacitance is significant for applications in semiconductor devices.
