Abstract

A simple method to fabricate high quality carbon nanoscrolls (CNSs) by exfoliation of natural flake graphite with the assistance of microwave sparks in liquid nitrogen is demonstrated. Field-effect transistors based on the CNSs show stable ambipolar behavior in both air and nitrogen, with maximum p-type and n-type mobilities in nitrogen of up to 3117 cm2 V−1 s−1 and 4595 cm2 V−1 s−1, respectively.
