Reliable (reported energy within 300 eV of a reference energy)
Comment:
n-type, Te-doped with a carrier density of 1.5E17 cm-3 GaSb(100)-(1x3) samples. Au foil in electrical contact with the sample was used for calibration. The samples were aligned by Laue diffraction to within 0.5 degree. width is 0.26 eV.
