Fabrication and characterization of field-effect transistors based on MoS2 nanotubes prepared in anodic aluminum oxide templates

Abstract

Field-effect transistors (FETs) based on MoS2 nanotubes prepared in anodic aluminum oxide (AAO) templates have been fabricated and demonstrated in this work. MoS2 nanotubes were prepared by the thermal decomposition of (NH4)2MoS4 precursors in the AAO template. The diameter of the MoS2 nanotubes was approximately 80 nm, which corresponded to the size of the AAO template. Schottky-type FETs were prepared with Au and Pt electrodes, and the FETs exhibited n-type behavior, with on/off ratios that exceeded 103 at VSD = 0.5 V.
