Challenge Problems
Push your limits with challenges.
Question 1
An intrinsic semiconductor has an electron concentration of 2 × 10^10 cm⁻³ at room temperature. Calculate the hole concentration and explain your reasoning based on the Mass Action Law.
💡 Hint: Ensure you know how to rearrange the Mass Action Law equation.
Question 2
Given that doping a semiconductor with phosphorus increases the electron concentration to 5 × 10^10 cm⁻³, calculate the new hole concentration if ni remains constant at 1 × 10¹⁰ cm⁻³.
💡 Hint: Use the Mass Action Law and remember how doping changes the distribution of carriers.
