Abstract
The InAs(001) 2 x 4 and 4 x 2 surfaces have been investigated by angle -resolved photoemission. The X(3) and X(5) points were found to be loc ated 6.0 and 2.7 eV below the valence band maximum, respectively, and the dispersion of bulk bands along the Gamma-X direction in the bulk B rillouin zone were well described by a theoretical calculation. From a ngle-resolved valence band spectra measured along the high symmetry di rections [110] and [1(1) over bar0$], three surface induced stares wer e identified on both the InAs(001)4 x 2 and the InAs(001)2 x 4 surface .
