- W2065644057 abstract "We have investigated the unoccupied electronic states of the Si-terminated (0001) surface of hexagonal 6H-SiC. The main problem with these surfaces is the reliable preparation of well defined surface reconstructions. We give reproducible methods to prepare the $(1ifmmodetimeselsetexttimesfi{}1),$ $(sqrt{3}ifmmodetimeselsetexttimesfi{}sqrt{3})R30ifmmode^circelsetextdegreefi{},$ $(3ifmmodetimeselsetexttimesfi{}3),$ and the $(6sqrt{3}ifmmodetimeselsetexttimesfi{}6sqrt{3})R30ifmmode^circelsetextdegreefi{}$ surface by controlled heating of the SiC sample in a Si flux. These surface reconstructions show a characteristic LEED pattern and a characteristic Si/C peak ratio in Auger electron spectroscopy. We present k-resolved inverse photoemission spectra for the $(1ifmmodetimeselsetexttimesfi{}1),$ $(sqrt{3}ifmmodetimeselsetexttimesfi{}sqrt{3})R30ifmmode^circelsetextdegreefi{},$ and $(3ifmmodetimeselsetexttimesfi{}3)$ surface. We compare the measured dispersion relations with ab initio local density approximation surface band structure calculations of the $(1ifmmodetimeselsetexttimesfi{}1)$- and the $(sqrt{3}ifmmodetimeselsetexttimesfi{}sqrt{3})R30ifmmode^circelsetextdegreefi{}$-reconstructed 6H-SiC(0001) surface and with a Mott-Hubbard model of the electronic ground state of the $(sqrt{3}ifmmodetimeselsetexttimesfi{}sqrt{3})R30ifmmode^circelsetextdegreefi{}$ and $(3ifmmodetimeselsetexttimesfi{}3)$ reconstruction. The comparison between experiment and theory supports the Hubbard model: The experiment determines a value of $U=2.0mathrm{eV}$ for the Mott-Hubbard Coulomb interaction parameter for the $(sqrt{3}ifmmodetimeselsetexttimesfi{}sqrt{3})R30ifmmode^circelsetextdegreefi{}$ reconstruction and $U=1.25mathrm{eV}$ for the $(3ifmmodetimeselsetexttimesfi{}3)$-reconstructed surface, respectively." @default.
