Title: Scanning tunneling microscopy of the atomically smooth (001) surface of vanadium pentoxide V{sub 2}O{sub 5} crystals

Abstract

The (001) cleavage surface of vanadium pentoxide (V{sub 2}O{sub 5}) crystal has been studied by scanning tunneling spectroscopy (STM). It is shown that the surface is not reconstructed; the STM image allows geometric lattice parameters to be determined with high accuracy. The nanostructure formed on the (001) cleavage surface of crystal consists of atomically smooth steps with a height multiple of unit-cell parameter c = 4.37 Å. The V{sub 2}O{sub 5} crystal cleavages can be used as references in calibration of a scanning tunneling microscope under atmospheric conditions both along the (Ñ…, y) surface and normally to the sample surface (along the z axis). It is found that the terrace surface is not perfectly atomically smooth; its roughness is estimated to be ~0.5 Å. This circumstance may introduce an additional error into the microscope calibration along the z coordinate.

  • The topography of the (001) surface of a high T/sub c/ superconducting HoBa/sub 2/Cu/sub 3/O/sub 7-//sub x/ single crystal was investigated in air using scanning tunneling microscopy. We found large, flat terraces separated by growth steps. The heights of these steps correspond to multiples of the c-axis lattice constant of 11.7 A of the perovskite structure. These steps have been verified by atomic force microscopy. On a smaller scale the flat terraces showed some fine structure with a corrugation height of 4 to 5 A and a lateral extent of several nanometers. In addition, we succeeded in creating nanometer-sized structuresmore » by increasing the sample bias voltage and tunneling current.« less
  • Scanning tunneling microscopy is used to study the surface structural and electronic properties of cleaved single crystals of Bi/sub 2.15/Sr/sub 1.7/CaCu/sub 2/O/sub 8+/delta// Images with atomic resolution reveal atomic chains with sinusoidal modulations running along the perovskite cell axis with a periodicity of 9 to 10 unit cells. These atomic chains stack along the /bold b/ direction with a translational vector of one unit, resulting in an incommensurate periodicity of about 4.75 units along the /bold a/ direction. In contrast to other reports, no evidence of ''missing Bi-atom rows'' is found. Spectroscopic studies show zero density of states at themore » Fermi level, implying that the surface Bi-O layer is nonmetallic.« less
  • The (001) surface of a highly doped ({approximately} 10{sup 19} cm{sup {minus}3}) n-type TiO{sub 2} crystal, following polishing, wet etching, and cleaning, was imaged in air with a Pt-Ir tip with a scanning tunneling microscope (STM). Good images of the surface could be obtained with the sample held at negative voltage (positive tip bias), with the high-resolution image showing only Ti atoms. Tunneling spectroscopy, involving the recording of i-V curves and dynamic conductance (di/dV)-V curves with the tip held over a given spot on the TiO{sub 2} surface, was also carried out. The resulting curves show electron tunneling into themore » conduction band and from the valence band, as well as a prominent peak identified as a surface state about 0.3 eV below the conduction band edge.« less
  • The electrochemical potential of an electrode containing the bronze H/sub 2x/V/sub 2/O/sub 5/ at equilibrium state has been measured for 0 < x < 1.7 in order to characterize the intermediate phases. /sup 51/V NMR, /sup 1/H NMR, and EPR studies have shown that interaction between different cations (V/sup 5 +/, V/sup 4 +/, V/sup 3 +/) plays an important role in the stability of these phases. The V/sup 3 +/ ion seems to be stabilized in a 3d/sub 1/4s/sub 1/ electronic configuration. 9 references, 8 figures, 2 tables.
