Low-voltage, High-performance Organic Field-Effect Transistors Based on 2D Crystalline Molecular Semiconductors.

ABSTRACT: Two dimensional (2D) molecular crystals have attracted considerable attention because of their promising potential in electrical device applications, such as high-performance field-effect transistors (FETs). However, such devices demand high voltages, thereby considerably increasing power consumption. This study demonstrates the fabrication of organic FETs based on 2D crystalline films as semiconducting channels. The application of high-κ oxide dielectrics allows the transistors run under a low operating voltage (-4 V). The devices exhibited a high electrical performance with a carrier mobility up to 9.8 cm² V^-1 s^-1. Further results show that the AlO_x layer is beneficial to the charge transport at the conducting channels of FETs. Thus, the device
