Which outcome results when gallium arsenide undergoes a solid-solid phase transition?

A)Change in carrier mobility occurs
B)Increased thermal conductivity observed
C)Crystal structure will remain constant
D)Dielectric constant remains unchanged

💡 Explanation

A shift in the gallium arsenide crystalline structure impacts its energy band gap, and electron flow; because the solid-solid transformations involves a change of the lattice constant via polymorphic transition, therefore charge mobility is altered rather than the thermal or dielectric properties remaining unchanged.
