Charlesworth, J.P.A., Godby, R.W. and Needs, R.J. (1993) First-principles calculations of many-body band-gap narrowing at an Al/GaAs(110) interface. Physical Review Letters, 70 (11). pp. 1685-1688. ISSN 0031-9007Full text not available from this repository.
We calculate the quasiparticle electronic structure of a Al/GaAs(110) Schottky barrier as a function of distance from the interface, using the GW self-energy operator. The GaAs band gap is significantly narrowed near the metal, although the classical picture of image-potential narrowing is subject to large quantum corrections. The nature of these corrections is explored further using model calculations.
