Fabrication of a Sexithiophene Semiconducting Wire: Nanoshaving with an Atomic Force Microscope Tip

Abstract

Nanoshaving with an atomic force microscope tip has been used to fabricate functional semiconducting wires from the molecular semiconductor sexithiophene (6T). Wires were carved to 300 (see Figure) and 70 nm widths. Time-dependent transport investigation in the wires revealed that they undergo reversible trapping of positive-charge carriers.
