Electronic Properties of Quaterrylene, C40H20

Abstract

Quaterrylene (C₄₀H₂₀) is a dark green-coloured aromatic hydrocarbon and is extraordinarily stable, as it can be heated to over 500°C without decomposition. The semiconduction of the aromatic hydrocarbon possesses a substantial anisotropy by a factor of 10⁷∼10⁸; the resistivity in the direction parallel to the b axis is 10⁶Ωcm. (for a single crystal) or 10⁵Ωcm. (for a surface-type cell) and that perpendicular to the b axis is 10¹³Ωcm. However, their energy gaps are around 0.6 eV.
