Do you think the operating temperatures of the p-n junction and transistor devices are important in terms of their operability? Explain your opinion clearly for reasons.

Answer 1

Opinions? You have to be kidding. Surely this did not come out of a world-class engineering institution. What does experience say about the density of charge carriers as a function of temperature? Band gap? threshold voltages? https://www.quora.com/What-is-the-effect-of-temperature-on-semiconductor-diode
