Mechanism of Ambipolar Field-Effect Transistors on One-Dimensional Organic Mott Insulators

Abstract

The experimentally observed, ambipolar field-effect characteristics of Mott insulators are reproduced in the one-dimensional Hubbard model attached to a tight-binding model for source and drain electrodes. The formation of Schottky barriers, originating from the work-function difference, is taken into account by a potential satisfying the Poisson equation with an appropriate boundary condition. Then, these field-effect characteristics are shown to be related by unique current-voltage characteristics of metal-Mott-insulator interfaces.
