The effect of deposition power on the electrical properties of Al-doped zinc oxide thin films
(2010)
We investigated the effect on the electronic properties of aluminum (Al)-zinc oxide (ZnO) films by modulating the radio frequency sputtering power. Our experimental results show that increasing the sputtering power increases ...
Ferrimagnetism of the magnetoelectric compound Cu2OSeO3 probed by Se-77 NMR
(2010)
We present a thorough 77Se NMR study of a single crystal of the magnetoelectric compound Cu2OSeO3.
The temperature dependence of the local electronic moments extracted from the NMR data is fully consistent
with a magnetic ...
Strain relaxation in Fe3O4/MgAl2O4 heterostructures: Mechanism for formation of antiphase boundaries in an epitaxial system with identical symmetries of film and substrate
(2009)
Strain relaxation studies in epitaxial magnetite, Fe3O4, thin films grown on MgAl2O4 100 substrates are
reported. The study shows that the films were relaxed in line with the theoretical model prediction with a
critical ...
Application of single crystalline tungsten for fabrication of high resolution STM probes with controlled structure
(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 ...
Effect of Catalyst Diameter on Vapour-Liquid-Solid Growth of GaAs Nanowires
(2014)
GaAs nanowires were grown on (111)B GaAs substrates using the vapour-liquid-solid mechanism. The Au/Pt nanodots used to catalyse wire growth were defined lithographically and had varying diameter and separation. An in-depth ...
Self-Assembly and Ordering of C-60 on the WO2/W(110) Surface
(2011)
The growth and ordering of C60 molecules on the WO2/W(110) surface have been
studied by low-temperature scanning tunnelling microscopy and spectroscopy (STM and
STS), low-energy electron diffraction (LEED) and density ...
Reflectance anisotropy spectroscopy of magnetite (110) surfaces
(2014)
Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and
thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, ...
