Growth and Electronic Transport in 9,10-Diphenylanthracene Single Crystals-An Organic Semiconductor of High Electron and Hole Mobility

摘要

Organic electronics has been a field of intense research interest for the last couple of decades. At this stage the need is to find an organic semiconducting material that is thermally stable over the operating temperatures and simultaneously offers high charge-carrier mobilities. A further challenge is imposed by the search for organic semiconductors exhibiting adequate transport for both electrons and holes for applications in ambipolar electronics or light-emitting transistors with balanced transport. In the past, high mobilities for electrons and holes were demonstrated in low-molecular-weight single crystals such as naphthalene, but the material itself is of less practical use due to its high vapor pressure even at room temperature impeding the formation of stable thin films.
