Which consequence results when applied strain modifies a semiconductor's band structure?

A)Change in optical absorption edge
B)Reduction in electron-phonon coupling
C)Increased thermal conductivity limits
D)Ferroelectric polarization domain collapse

💡 Explanation

Changing the band structure via strain alters the minimum energy for electron excitation, which shifts the optical absorption edge because strain affects the atomic spacing which modifies the electronic band structure; therefore the absorption edge shifts, rather than phonon interactions being reduced or thermal conductivity being increased.
