Abstract

Elemental Te displays a wide variety of nanoscale morphologies of vapor-deposited films, depending on the substrate surface and temperature. These morphologies are correlated to field-effect mobilities in transistors made with Te as the lone semiconductor or from Te-organic multilayer semiconductors. Two examples of morphologies and transistor output characteristics, i.e., on a room temperature oxide and heated organic, are shown in the figure.
