The hopping mechanism of hole transport in thin diaryldiacetylene laye
rs prepared by thermal deposition in vacuum is investigated. Drift mob
ility in the systems studied is found to attain 10(-4) cm(2)/(V.s). Th
e basic transport characteristics of charge carriers in these systems
and their dependence on the electric field intensity, temperature, and
chemical composition of diaryldiacetylenes are determined.
