Critical field behavior and antiband instability under controlled surface electromigration on Si(111)
SHVETS, IGOR; USOV, VICTOR; O'COILEAIN, CORMAC (2011)In this study we investigate step bunching and antiband surface instabilities on Si(111). We experimentally study the effects of a controlled electromigration field on the onset of antibands. We analyze the initial stage ... -
Developments in surface magneto-optical Kerr effect setup for ultrahigh vacuum analysis of magnetic ultrathin films
SHVETS, IGOR; USOV, VICTOR; MURPHY, SHANE (2005)We describe a surface magneto-optical Kerr effect (SMOKE) setup designed to study the magnetic properties of ultrathin films in ultrahigh vacuum (UHV). As in earlier systems, a crossed-poles electromagnet is used, which ... -
Epitaxial growth and magnetic properties of Fe nanowedge islands on Mo(110)
SHVETS, IGOR; MURPHY, SHANE; USOV, VICTOR (2005)Fe films with a nominal thickness greater than or equal to 2 Angstrom grown on Mo(1 10) at 500 less than or equal to Tless than or equal to 750 K self-assemble into nanowedge islands supported on a pseudomorphic Fe wetting ... -
Equilibrium faceting formation in vicinal Al2O3 (0001) surface caused by annealing
FOX, DANIEL; SHVETS, IGOR; FLEISCHER, KARSTEN; ZHANG, HONGZHOU; USOV, VICTOR; VERRE, RUGGERO; SOFIN, SUMESH; BEHAN, G. (Elsevier B.V., 2012-07)We report on a heat-induced transformation of the surface of ?-alumina (0001) crystals which have an off-cut in the [1-210] direction. Annealing the crystal causes the surface to transform into a regular array of (0001) ... -
Manipulating and probing the growth of plasmonic nanoparticle arrays using light
BULFIN, BRENDAN; FLEISCHER, KARSTEN; USOV, VICTOR; MCGILP, JOHN; SHVETS, IGOR (2013)Highly ordered self-assembled silver nanoparticle (NP) arrays have been produced by glancing angle deposition on faceted c-plane Al2O3 templates. The NP shape can be tuned by changing the substrate temperature during ... -
Planar nanowire arrays formed by atomic-terrace low-angle shadowing
SHVETS, IGOR; USOV, VICTOR; MURPHY, SHANE; O COILEAIN, CORMAC LUKE (2008)A relatively simple method for preparation of planar nanowire arrays on vicinal substrates by molecular beam epitaxy is presented. The atomic step-and-terrace morphology of vicinal substrates is used to produce a shadowing ... -
Study of ferromagnetic-paramagnetic phase transition in two-dimensional Fe/Mo(110) epitaxial films
SHVETS, IGOR; USOV, VICTOR; MURPHY, SHANE (2005)Epitaxial Fe films were grown on a Mo(1 1 0) single crystal surface at different temperatures. The relationship between magnetism and film morphology was studied in situ using scanning tunneling microscopy and Kerr ... -
Study of in-plane magnetic anisotropy of ultrathin epitaxial Fe films grown on vicinal Mo(110) surface
SHVETS, IGOR; MURPHY, SHANE; USOV, VICTOR (2004)In situ surface magneto-optical Kerr effect was used in conjunction with scanning tunneling microscopy and low-energy electron diffraction to study the in-plane magnetic anisotropy of ultrathin Fe films on a vicinal Mo(110) ...
