← ScienceWhich outcome impairs doped silicon crystal performance under high current?
A)Increased electron-hole recombination rate✓
B)Reduced thermal conductivity anisotropy
C)Elevation of the Debye temperature
D)Enhanced generation of Frenkel defects
💡 Explanation
Increased electron-hole recombination occurs due to increased crystal lattice temperatures activating phonon interactions. This phonon scattering reduces carrier mobility because electron-hole recombination rate goes up with temperatures, therefore degrading performance, rather than other options that imply improved behaviors under stress
