Ab-initio electronic structure calculations and properties of [SixSn1 − x]3N4 ternary nitrides
Pavloudis, T.; Zervos, Matthew; Komninou, P.; Kioseoglou, J. (2016)We carry out ab initio electronic structure calculations of (SixSn1 − x)3N4 using density functional theory with projector augmented-wave potentials under the generalized gradient approximation. We find that the energetically ...

Broad compositional tunability of indium tin oxide nanowires grown by the vapor-liquid-solid mechanism
Zervos, Matthew; Mihailescu, C. N.; Giapintzakis, John; Luculescu, C. R.; Florini, N.; Komninou, Ph; Kioseoglou, J.; Othonos, A. (2014)Indium tin oxide nanowires were grown by the reaction of In and Sn with O2 at800 °C via the vapor-liquid-solid mechanism on 1 nm Au/Si(001). We obtain Sn doped In2O3 nanowires having a cubic bixbyite crystal structure by ...

Si nanostructures grown by picosecond high repetition rate pulsed laser deposition
Pervolaraki, M.; Komninou, Ph; Kioseoglou, J.; Athanasopoulos, G. I.; Giapintzakis, John (2013)One-step growth of n-doped Si nanostructures by picosecond ultra fast pulsed laser deposition at 1064nm is reported for the first time. The structure and morphology of the Si nanostructures were characterized by X-ray ...

Structural properties of SnO2 nanowires and the effect of donor like defects on its charge distribution
Zervos, Matthew; Othonos, A.; Tsokkou, D.; Kioseoglou, J.; Pavlidou, E.; Komninou, P. (2013)Tin oxide (SnO2) nanowires (NWs) with diameters of 50 nm, lengths up to 100 μm and a tetragonal rutile crystal structure have been grown by low pressure reactive vapour transport on 1 nm Au/Si(001). The free carrier density ...

Thermal oxidation and facet-formation mechanisms of Si nanowires
Kioseoglou, J.; Komninou, P.; Zervos, Matthew (2014)Silicon nanowires were grown along the [111] direction on Si(001) by the vapor-liquid-solid mechanism using 1 nm Au as a catalyst. They were subsequently oxidized at 900 °C for 60 min, 120 min and 180 min, which lead to ...

Ultrafast pulsed laser deposition of carbon nanostructures: Structural and optical characterization
Pervolaraki, M.; Komninou, P.; Kioseoglou, J.; Othonos, A.; Giapintzakis, John (2013)Carbon nanostructured materials were obtained by high-repetition rate pulsed laser ablation of a graphite target using a train of 10-ps duration pulses at 1064 nm in different pressures of high-purity Ar gas. It is ...
