WebWe present evidence for the interrelationship between a metal (non-oxygen)semiconductor reaction and formation of the band-gap defect states at a buried oxide-semiconductor interface by investigating well-defined epitaxial BaO/Ge (100) junctions with high-resolution synchrotron-radiation photoelectron spectroscopy. WebAbstract. Advanced beyond-silicon electronic technology requires both channel materials and also ultralow-resistance contacts to be discovered 1,2. Atomically thin two-dimensional semiconductors have great potential for realizing high-performance electronic devices 1,3. However, owing to metal-induced gap states (MIGS) 4-7, energy barriers at ... rank-biased overlap

Web4 okt. 2001 · The sharp increase at the interface corresponds to the metal-induced gap states. Our nanotube transistors can be classified as enhancement-mode p -type FETs ( 21 ), because a strong modulation of the current through the nanotube FET is possible when a small negative gate voltage is applied. Web21 sep. 2007 · Barrier heights of real Schottky contacts explained by metal-induced gap states and lateral inhomogeneities W. Mönch Physics 1999 Most metal–semiconductor contacts are rectifying. For moderately doped semiconductors, the current transport across such Schottky contacts occurs by thermionic emission over the Schottky barrier. The… 402 Web7 mrt. 2024 · We present evidence that metal-induced gap states (MIGS) are the origin for the large FLP similar to conventional semiconductors. A variety of TMDCs (MoSe 2, WSe 2, WS 2, and MoTe 2) were investigated using high-spatial-resolution surface characterization techniques, permitting us to distinguish between defected and pristine regions. owl 3 manual
