Which mechanism decreases semiconductor device efficiency at ultra-high densities?

A)Multi-orbital electron-electron scattering
B)Phonon-mediated thermal energy transfer
C)Reduced plasmon frequency coupling
D)Auger recombination through band-overlap

💡 Explanation

Multi-orbital electron-electron scattering causes energy loss because interactions between electrons in clustered orbitals lead to non-radiative transitions, therefore reducing luminescence, rather than efficient photon production or band-to-band recombination.
