New method for control of Schottky-barrier height

Abstract
Ultrathin reactive Al interlayers at ultrahigh vacuum‐cleaved Au‐CdS, CdSe single‐crystal interfaces have been used to continuously tune the effective Schottky‐barrier height over the full range reported for metals on these prototypical II‐VI semiconductors, i.e., 0–0.8 eV. Measured electrical transport properties are correlated with observed features of atomic interdiffusion chemistry and valence electronic structure.
