← ScienceWhich outcome occurs when compressive stress exceeds the critical level normal to GaAs crystal lattice planes?
A)Increased electron-hole recombination velocity✓
B)Elevated critical superconduction temperature
C)Decreased dielectric breakdown strength
D)Reduced lattice dislocation propagation rate
💡 Explanation
Increased electron-hole recombination happens because exceeding the critical stress induces piezoelectric effects resulting in dislocations acting as recombination centers; therefore, option A, rather than other options, represents a response related specifically to stress-induced defects.
