High performance n-type single crystalline transistors of naphthalene bis(dicarboximide) and their anisotropic transport in crystals

Abstract

High-performance n-type organic single crystal transistors of a naphthalene diimide are demonstrated. The accomplished transistors exhibit electron mobility as high as 0.7 cm² V⁻¹ s⁻¹. The anisotropic charge transport in the elongated hexagonal crystals of the naphthalene diimide is also explored. The transport anisotropy along different directions is at least 1.6 (mobility ratio).
