Abstract
Experimental studies of excess hole carrier mobilities in carbazole mo dified polysiloxanes reveal a complex variation with electric field an d temperature. For a specific material, the data may be successfully i nterpreted by applying either a modified Poole-Frenkel or disorder-lim ited hopping analysis. Model parameters derived from the hopping forma lism display greater consistency however when comparison is made for p olymers possessing different backbone lengths.
