Enhanced Charge-Carrier Mobility in High-Pressure-Crystallized Poly(3-hexylthiophene)

Comparison of properties of poly(3-hexylthiophene)s solidified by different procedures – ranging from solution- and melt-casting to crystallization under high pressure – suggests that not only the overall degree of order, i.e. crystallinity, but also the thickness l of the crystalline entities in such semicrystalline semiconducting structures can significantly influence their charge-transport properties, with an increase of the bulk charge-carrier mobility of up to two orders being observed in time-of-flight photoconductivity experiments for systems comprising crystalline features of enlarged l realised by pressure-induced crystallization.
