摘要: The Fermi-level movement in a Schottky barrier is investigated using bimetal thin-film structure. functional dependence of the height on inner metal thickness formulated terms effective screening length and interface trap states. This model used to describe experimental results Pt-Ti-GaAs Ti-Pt-GaAs diodes. It found that lengths for Pt Ti are 6.5 7.0 AA, respectively, significantly greater than ideal values theory N.F.
