Implication

Experimental analysis demonstrates Gaussian charge dispersion in molecularly doped polymers, indicating both diagonal and off-diagonal disorder govern carrier transport.

Key Points

To identify the physical mechanisms governing the dispersion of transiting charge carriers in molecularly doped polymer systems.
Analyzed normalized time-of-flight current transients in polycarbonate molecularly doped with N,N′-diphenyl-N,N-bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′-diamine.
Evaluated current signals across varied electric fields, sample thicknesses, and operational temperatures.
Transiting carriers reach dynamic equilibrium within a small fraction of the total transit time and exhibit dispersion governed by time-dependent Gaussian statistics.
Gaussian dispersion bandwidth broadens at higher electric fields due to off-diagonal disorder, while dispersion narrows at elevated temperatures and reaches a finite, field-independent plateau at long transit times due to diagonal disorder.
