Challenge Problems
Push your limits with challenges.
Question 1
Calculate how an increase in temperature from 0 K to a higher temperature affects the conductivity of a semiconductor. Given that the intrinsic carrier concentration (ni) typically doubles from a known point, explain the impact on conductivity.
💡 Hint: Consider how the relationship between temperature and carrier concentration plays a crucial role in conductivity.
Question 2
Discuss how the addition of impurities to Silicon could influence its conductivity compared to pure Silicon at room temperature.
💡 Hint: Think about how controlling the electrons changes the electronic properties of the semiconductor.
