Which mechanism limits carrier mobility in organic molecular semiconductors under intense illumination?

A)Polaron formation increasing effective mass
B)Band gap widening decreasing conductivity
C)Surface recombination reducing carrier lifetime
D)Auger scattering depleting mobile carriers

💡 Explanation

Under intense illumination, organic molecular semiconductors experience polaron formation because excess charge carriers distort the lattice, creating localized states with stronger electron-phonon interactions effectively increasing the carrier's mass, which then limits mobility. Therefore polaron formation limits motility rather than gap widening, recombination or scattering which require different interaction processes.
