← ScienceWhich constraint on germanium transistors increases sharply when temperature rises?
A)Minority carrier concentration increases rapidly✓
B)Debye length remains constant
C)Majority carrier mobility decreases linearly
D)Acceptor doping concentration remains constant
💡 Explanation
Increased temperature rapidly boosts the minority carrier concentration because thermal energy allows electrons to jump the band gap, overwhelming the doping, therefore transistor function fails as excess carriers cause short circuits rather than maintaining semiconducting qualities.
