The electric properties of a metal/organic/inorganic heterostructure were explored by current–voltage ( I – V ), feedback charge capacitance ( C – V ) and charge transient spectroscopy (QTS). Temperature dependent I – V characteristics from 1

For a large number of organic disordered semiconductors the transport of electrons or holes via hopping is mediated by localized states in the band gap. An attempt is presented towards testing the widely met hopping transport model based on the assum

Transient charging in response to pulsed bias of copper phthalocyanine (CuPc) organic thin films on indium–tin–oxide (ITO) was investigated by charge transient spectroscopy (QTS) in situ under ultra-high vacuum conditions. The charge relaxation p

Steady-state current-voltage (IV) characteristics of metal/organics/metal devices are modelled on the basis of thermionic emission into two back-to-back connected diodes separated by a series bulk resistance. It is shown that the analysis of the IV c
