Which risk increases in crystalline semiconductor devices operating at elevated temperatures?

💡 Explanation

Increased thermal energy excites electrons across the band gap, increasing intrinsic carrier concentration of the semiconductor, which weakens the effect of doping because intrinsic carriers overwhelm impurity carriers; therefore extrinsic behavior fails, rather than changes relating to Fermi level or exciton dynamics.
