Application of single crystalline tungsten for fabrication of high resolution STM probes with controlled structure
SHVETS, IGOR; LUBBEN, OLAF; CHAIKA, ALEXANDER (2011)The possibility to fabricate scanning tunneling microscopy (STM) probes with controlled electronic structure using single crystalline tungsten tips is discussed. High resolution power of oriented single crystalline probes ... -
Fe Nanoclusters on the Ge(001) Surface Studied by Scanning Tunnelling Microscopy, Density Functional Theory Calculations and X-Ray Magnetic Circular Dichroism
SHVETS, IGOR; LUBBEN, OLAF; KRASNIKOV, SERGEY; MURPHY, BARRY (2011)The growth of Fe nanoclusters on the Ge(001) surface has been studied using low-temperature scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. STM results indicate that Fe nucleates on ... -
Finite element method simulations of heat flow in fixed bed solar water splitting redox reactors
SHVETS, IGOR; LUBBEN, OLAF; KRASNIKOV, SERGEY; MURPHY, BARRY; BULFIN, BRENDAN (2012)An improved design for radiation absorption and heat flow into materials with low thermal conductivity is demonstrated. The design was developed for application in fixed bed two step solar water splitting redox reactors. ... -
Growth and ordering of Ni(II) diphenylporphyrin monolayers on Ag(111) and Ag/Si(111) studied by STM and LEED
SHVETS, IGOR; MURPHY, BARRY; SENGE, MATHIAS; SERGEEVA, NATALIA; LUBBEN, OLAF; KRASNIKOV, SERGEY (2012)The room temperature self-assembly and ordering of (5,15-diphenylporphyrinato)nickel(II) (NiDPP) on the Ag(111) and Ag/Si(111)-(?3 ? ?3)R30? surfaces have been investigated using scanning tunnelling microscopy and low-energy ... -
Rotational transitions in a C60 monolayer on the WO2/W(110) surface
SHVETS, IGOR; KRASNIKOV, SERGEY; LUBBEN, OLAF; MURPHY, BARRY; WU, HAN-CHUN; BULFIN, BRENDAN (2011)Variable-temperature scanning tunneling microscopy (STM) is shown to be an effective technique to study two-dimensional phase transitions. Observations show that a monolayer of C60 deposited on an ultrathin WO2 layer grown ... -
Selecting the tip electron orbital for scanning tunneling microscopy imaging with sub-?ngstrom lateral resolution
SHVETS, IGOR; BOZHKO, SERGEY; KRASNIKOV, SERGEY; LUBBEN, OLAF (Institute of Physics, 2010)We report on scanning tunneling microscopy (STM) studies performed with single crystalline W[001] tips on a graphite(0001) surface. Results of distance-dependent STM experiments with sub-?ngstrom lateral resolution and ...
