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 ...

Structural properties of SnO2 nanowires and the effect of donor like defects on its charge distribution
Zervos, Matthew; Othonos, Andreas S.; Tsokkou, Demetra; 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, Maria; Komninou, P.; Kioseoglou, J.; Othonos, Andreas S.; Giapintzakis, Ioannis (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 ...
