Metal induced gap states

Web9 dec. 2009 · Pinning can arise from either intrinsic (metal induced gap states, MIGs) or extrinsic (defects) mechanisms. Identifying the correct mechanism is not trivial, as both mechanisms follow similar chemical trends. However knowing the correct mechanism is important, as only extrinsic mechanisms can be corrected by varying processing conditions. http://large.stanford.edu/courses/2007/ap272/kimdh1/

WebThe atomic-site projected electronic density of states and the charge density, calculated as a function of the distance from the interface, show that the gap states induced into the semiconductor by the presence of Al are strongly localized in the interface region with a decay length λ~ 3.5 a.u. WebThese MIGS are characterized by a spatially growing measured gap in the local density of states (L-DOS) of the MoS2 within 2 nm of the metal-semiconductor interface. Their decay lengths extend from a minimum of ~0.55 nm near mid gap to as long as 2 nm near the band edges and are nearly identical for Au, Pd and graphite contacts, indicating that ...
