Scanning Tunneling Spectroscopy of Ni/W(110): bcc and fcc properties in the second atomic layer
arXiv:1303.1357 · doi:10.1007/s00339-012-7523-0
Abstract
Nickel islands are grown on W(110) at elevated temperatures. Islands with a thickness of two layers are investigated with scanning tunneling microscopy. Spectroscopic measurements reveal that nanometer sized areas of the islands exhibit distinctly different apparent heights and dI/dV spectra. Spin polarized and paramagnetic band structure calculations indicate that the spectral features are due to fcc(111) and bcc(110) orientations of the Ni film, respectively.
