Challenge Problems
Push your limits with advanced challenges
Given a p-type material with a hole concentration of 10^15 cm^-3 and n-type material with electron concentration of 10^16 cm^-3, explain how the formation of the depletion region will change if the temperatures increase significantly. Consider carrier concentrations and recombination rates in your explanation.
💡 Hint: Think about the behavior of charge carriers with increased thermal energy.
Design an experiment to measure the built-in potential of a PN junction diode. Discuss what equipment would be needed and how the experiment would demonstrate the concept of the depletion region.
💡 Hint: Focus on using I-V curves to extract meaningful information about voltages.
