Challenge Problems
Push your limits with challenges.
Question 1
Consider two hypothetical semiconductors, A (p-type with high doping) and B (n-type with low doping). Discuss how the formation of their junction would differ in terms of depletion layer width and junction potential compared to two equal doping levels.
💡 Hint: Think about how doping levels affect charge carrier availability.
Question 2
Calculate the junction potential across a p-n junction given the intrinsic carrier concentration and doping levels if n-type has a concentration of 10^16/cm³ and p-type has 10^14/cm³.
💡 Hint: Consider the relationship between doping levels and potential.
