摘      要：A key requirement for well performing devices based onorganic semiconductors is to ensure ohmic contacts, where anefficient hole and electron injection and extraction can beachieved at the electrode/semiconductor interfaces. The usualway to obtain ohmic contacts involves fine tuning of the energet-ics at the interfaces by using dopants (p- type and n-type) to con-trol the Fermi level of the semiconductor [1,2], or using suitablemetals or metal oxides as electrodes [3].
