E ectively atomically at GaAs=AlAs interfaces over a macroscopic area ("super-at interfaces") have been realized in GaAs=AlAs and GaAs=(GaAs)2 (AlAs)2 quantum wells (QWs) grown on (4 1 1)A GaAs substrates by molecular beam epitaxy (MBE). A single and very sharp photoluminescence (PL) peak was observ
