摘要
The surface core level shifts of (2 x 4), c(4 x 4), and (4 x 6) reconstructured GaAs(001) surfaces, which were prepared in optimized molecular beam epitaxy growth conditions, have been investigated by in situ synchrotron radiation high-resolution photoemission. The numbers of chemically inequivalent Ga and As surface sites were determined from the curve-fitting results of the high-resolution core level photoemission spectra.
