ABSTRACT
We show that a new concept of amphoteric native defects with strongly Fermi level dependent defect formation energy provides the basis for a unified explanation of a large variety of phenomena in semiconductors. Formation of Schottky barriers, particle irradiation induced compensation, doping-induced superlattice intermixing, and limits of free-carrier concentration find for the first time a common simple explanation.

    A central question in the study of high-temperature superconductivity is whether this phenomenon is linked to the doped antiferromagnetic Mott insulator or whether it emerges from a Fermi-liquid state across the whole cuprate phase diagram. Discriminating between these orthogonal cases hinges on...

We find that antimony doping and increase iron content in interstitial effect have both the effect to slightly decrease the...

    We present a method of measurement of the current-voltage (I-V ) and conductance-voltage (G-V ) characteristics of nanowires with quantum point contact formed at the Co-Ge99.99Ga0.01 interface. The effect of the Fermi level pinning leads to the formation of an ohmic contact between Co and...

    Surface potential profiles of the junction area of a cleaved n-Si(100)/HfO2/p+-polycrystalline silicon (poly-Si) gate stack reveal a dipole potential in the oxide, hole trapping at the HfO2/poly-Si interface, with the Fermi level ∼0.4 eV below the Si conduction bandedge and enhanced and...
