Reliable (reported energy within 300 eV of a reference energy)
Comment:
1 ML K/Si(111)-(R3xR3)R30-B. The substrate was prepared by exposing the clean lightly-doped n-type surface (7x7) with a resistivity of 1 ohm cm to B10H14 and by annealing (T = 1173 K). The spectra were recorded at normal emission.
