Which outcome occurs when silicon doping alters gallium arsenide molecular orbitals?

A)Decreased Schottky junction barrier height
B)Increased covalent bond energy overall
C)Enhanced piezoelectric material properties
D)Reduced thermal expansion coefficient value

💡 Explanation

A Schottky barrier's height decreases because silicon doping introduces donor states modifying the band bending and therefore Fermi level alignment. A lower barrier results, rather than changes in bond strengths or piezoelectricity because those are different mechanisms with varied preconditions.
