← ScienceWhich consequence results when surface plasmon resonance increases bandgaps during aluminum gallium arsenide fabrication?
A)Decreased free carrier concentration results✓
B)Increased refractive index occurs
C)Higher photon absorption originates throughout
D)Augmented thermal conductivity transfers efficiently
💡 Explanation
Reduced free carrier concentration occurs, because surface plasmon resonance widens the band gap by altering material dielectric properties; therefore fewer electrons achieve sufficient energies, rather than increased photon absorption or changes in refractive index that have different triggers.
