Synthesis and Characterization of Atomically Flat Methyl-Terminated Ge(111) Surfaces.
Atomically flat, terraced H-Ge(111) was prepared by annealing in H2(g) at 850 °C. The formation of monohydride Ge-H bonds oriented normal to the surface was indicated by angle-dependent Fourier-transform infrared (FTIR) spectroscopy. Subsequent reaction in CCl3Br(l) formed Br-terminated Ge(111), as shown by the disappearance of the Ge-H absorption in the FTIR spectra concomitant with the appear...
متن کاملBuckling and band gap of the Ge(111)2×1 surface studied by low-temperature scanning tunneling microscopy
Low-temperature scanning tunneling microscopy is used to study the 2×1 reconstruction of cleaved Ge(111) surfaces. Buckling of the surface atoms is investigated by observations of the corrugation shift between filled and empty states. In the direction, the shift in corrugation maxima from filled to empty states is found to be negative, consistent with expectations for the “negatively buckled" m...
متن کاملFormation of linearly linked Fe clusters on Si(111)-7 × 7-C2H5OH surface
UNLABELLED The Fe atoms were deposited on the Si(111)-7 × 7 surface, which has been saturated with the C2H5OH molecules. Then, the Fe clusters were formed on Si(111)-7 × 7-C2H5OH surface and in situ observed by the scanning tunneling microscopy (STM). The STM images showed that with the increase of Fe clusters, the size of clusters was about 5 nm and they self-assembled in straightly linked cha...
متن کاملReconstructions of the InP„111...A surface
Indium phosphide was deposited on InP(111)A substrates by metalorganic vapor-phase epitaxy. Then, the surface was characterized by scanning tunneling microscopy, low-energy electron diffraction, and x-ray photoelectron spectroscopy. Two reconstructions were observed: the (232) and the ()3))R30° with phosphorus coverages of 0.25 and 1.0060.05 ML ~monolayers!, respectively. The (232) was found to...
متن کاملScanning tunneling microscopy and spectroscopy of wet-chemically prepared chlorinated Si111 surfaces.
Chlorine-terminated Si(111) surfaces prepared through the wet-chemical treatment of H-terminated Si(111) surfaces with PCl5 (in chlorobenzene) were investigated using ultrahigh vacuum scanning tunneling microscopy (UHV cryo-STM) and tunneling spectroscopy. STM images, collected at 77 K, revealed an unreconstructed 1 x 1 structure for the chlorination layer, consistent with what has been observe...
