Abstract

Charge transport has been studied in a germanium-centred oligothiophene cruciform featuring 2-D close packing in the bulk. The morphology has been found to play a significant role in charge carrier transport, evidenced by time-of-flight and field effect transistor measurements. Thermal step-annealing leads to the formation of smaller crystalline domains which are favourable for charge transport in device applications.
