← ScienceWhich consequence results when cadmium telluride crystal growth flaws?
A)Decreased electron-hole recombination lifetime✓
B)Increased grain boundary carrier mobility
C)Enhanced radiative heat transfer coupling
D)Phonon scattering mean free path increases
💡 Explanation
Flaws in cadmium telluride increase non-radiative recombination because of point defects acting via Shockley-Read-Hall recombination. Therefore, the electron-hole recombination lifetime decreases, rather than alternative changes to radiative transfer, a different process.
