      Carrier relaxation dynamics in SnxNy nanowires grown by chemical vapor deposition 

      Othonos, Andreas S.; Zervos, Matthew (2009)
      Carrier relaxation dynamics in tin nitride (SnxNy) nanowires have been investigated using femtosecond transient absorption spectroscopy. The nanowires were grown directly on quartz using chemical vapor deposition and had ...

      Femtosecond carrier dynamics in In 2O 3 nanocrystals 

      Othonos, Andreas S.; Zervos, Matthew; Tsokkou, Demetra (2009)
      We have studied carrier dynamics in In 2O 3 nanocrystals grown on a quartz substrate using chemical vapor deposition. Transient differential absorption measurements have been employed to investigate the relaxation dynamics ...

      Sn doped β-Ga2O3 and β-Ga2S3 nanowires with red emission for solar energy spectral shifting 

      Zervos, Matthew; Othonos, Andreas S.; Gianneta, V.; Travlos, A.; Nassiopoulou, Androula Galiouna (2015)
      Sn doped β-Ga2O3 nanowires have been grown on Si(001) via the vapor-liquid-solid mechanism at 800 °C over a broad range of compositions. These have a monoclinic β-Ga2O3 crystal structure and minimum resistances for 1-2 at. ...

      Surface passivation and conversion of SnO2 to SnS2 nanowires 

      Zervos, Matthew; Mihailescu, C. N.; Giapintzakis, Ioannis; Othonos, Andreas S.; Luculescu, C. R. (2015)
      SnO2 nanowires have been grown on Si(0 0 1) via the vapour-liquid-solid mechanism at 800 °C and then exposed to H2S between 300 and 600 °C. The SnS2/SnO2 nanowires obtained at 300 °C consist of tetragonal rutile SnO2 and ...

      A systematic study of the nitridation of SnO 2 nanowires grown by the vapor liquid solid mechanism 

      Zervos, Matthew; Othonos, Andreas S. (2012)
      SnO 2 nanowires (NWs) with diameters of 50 nm and lengths ≥10 μm have been grown at 800 °C on 1.0 nm Au/Si(001) via the vapor liquid solid mechanism and the low pressure chemical vapor deposition. These exhibited clear ...
