Description

Rubrene is a novel organic semiconductor, with many interesting electronic properties. Among organic semiconductors, rubrene has the highest carrier mobility, with values reaching 40 cm2/(V S). These electronic properties, however, are only applicable for crystallized and pure forms of rubrene. Physical vapor transport of rubrene is capable of purifying and crystallizing rubrene powder. This is accomplished by heating the impure sample and subjecting the sublimated vapors with a constant flow of Ar gas along a temperature gradient. We report efforts to build and test a physical vapor growth system for rubrene.
