Broad compositional tunability of indium tin oxide nanowires grown by the vapor-liquid-solid mechanism
Zervos, Matthew; Mihailescu, C. N.; Giapintzakis, Ioannis; Luculescu, C. R.; Florini, N.; Komninou, Ph; Kioseoglou, J.; Othonos, Andreas S. (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 ...

Electrical, structural, and optical properties of sulfurized Sn-doped In2O3 nanowires
Zervos, Matthew; Mihailescu, C. N.; Giapintzakis, Ioannis; Othonos, Andreas S.; Travlos, A.; Luculescu, C. R. (2015)Sn-doped In2O3 nanowires have been grown on Si via the vapor-liquid-solid mechanism at 800 °C and then exposed to H2S between 300 to 600 °C. We observe the existence of cubic bixbyite In2O3 and hexagonal SnS2 after processing ...

Low Temperature Synthesis as a Route for Highly Thermoelectric Efficient Na-Doped PbTe
Papageorgiou, Chryssi; Delimitis, Andreas; Symeou, Elli; Giapintzakis, Ioannis; Kyratsi, Theodora (2018)In this work, Na-doped PbTe is synthesized through a low temperature synthesis technique. This method provides highly efficient p-type PbTe using a synthesis temperature much lower than the PbTe melting point and as low ...

Matrix assisted pulsed laser evaporation of Mn 12(Propionate) thin films
Pervolaraki, Maria; Sima, Felix N.; Socol, G.; Teodorescu, C. M.; Gheorghe, N. G.; Socol, M.; Mihailescu, Ion N.; Moushi, Eleni E.; Tasiopoulos, Anastasios J.; Athanasopoulos, Georgios I.; Viskadourakis, Zacharias A.; Giapintzakis, Ioannis (2012)Single molecule magnets are of great interest due to a multitude of potential applications for some of which thin films are required. Traditional physical vapor deposition techniques are not suitable for the deposition of ...

Sulfur doping of M/In2O3 (M=Al,W) nanowires with room temperature near infra red emission
Zervos, Matthew; Mihailescu, C.; Giapintzakis, Ioannis; Othonos, Andreas S.; Travlos, A. (2015)We have investigated the growth of Al doped In2O3 nanowires via the vapor-liquid-solid mechanism at 800°C using Au as a catalyst. We find that the Al is not incorporated into the cubic bixbyite crystal structure of In2O3 ...
