Titel:
Barrier heights of organic modified Schottky contacts: theory and experiment 
Abstract:
The impact of thin organic films on the barrier heights of Ag/n-GaAs(0 0 1) Schottky contacts is investigated using complementary experimental and theoretical techniques, namely current–voltage (I–V) measurements, impedance spectroscopy, and internal photoemisson spectroscopy, as well as drift diffusion simulations. The in situ current–voltage characteristics show that the effective barrier height decreases by ∼200 meV as a function of the 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) lay...    »
