Which phenomenon limits electron mobility in molecular semiconductors at elevated temperatures?

💡 Explanation

At elevated temperatures, increased lattice vibrations (phonons) enhances phonon scattering, disrupting the coherent electron transport in molecular semiconductors, which limits mobility. Therefore phonon scatttering predominates, rather than tunneling, elevated Fermi level shifts, or electron repulsion which are less temperature-dependent.
