ABSTRACT
We have fabricated Ge metal-insulator-semiconductor structures with ultrathin pure germanium nitride (Ge3N4) films by the direct nitridation of germanium (Ge) substrates. The plasma-enhanced nitridation technique was used with dc plasma source at low temperatures. Capacitance–voltage characteristics with no hysteresis and capacitance equivalent thickness of 1.23 nm have been achieved.

    A physical model of the metallic-type conductivity at the interface between an organic semiconductor or dielectric and a metals or another organic material is proposed. The conductivity arises due to the formation of geminal pairs with a rather high surface density at the interface. Conditions...
