      Carrier dynamics in InS nanowires grown via chemical vapor deposition 

      Othonos, Andreas S.; Zervos, Matthew (2010)
      Transient femtosecond absorption spectroscopy and timecorrelating single photon counting (TCSPC) photoluminescence (PL) were employed to study InS nanowires (NWs) grown by chemical vapor deposition (CVD) and determine the ...

      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 ...

      Linear dynamic polarizability and the absorption spectrum of an exciton in a quantum ring in a magnetic field 

      Ghazaryan, A. V.; Djotyan, Anahit P.; Moulopoulos, Konstantinos; Kirakosyan, Albert A. (2011)
      The problem of an electron-hole system interacting through a contact potential and moving in a one-dimensional quantum ring threaded by an Aharonov-Bohm flux is considered, with respect to the system's energetics as well ...

      Tin oxide nanowires: The influence of trap states on ultrafast carrier relaxation 

      Othonos, Andreas S.; Zervos, Matthew; Tsokkou, Demetra (2009)
      We have studied the optical properties and carrier dynamics in SnO 2 nanowires (NWs) with an average radius of 50 nm that were grown via the vapor-liquid solid method. Transient differential absorption measurements have ...

      Ultrafast carrier relaxation in inn nanowires grown by reactive vapor transport 

      Othonos, Andreas S.; Zervos, Matthew; Pervolaraki, Maria (2009)
      We have studied femtosecond carrier dynamics in InN nanowires grown by reactive vapor transport. Transient differential absorption measurements have been employed to investigate the relaxation dynamics of photogenerated ...

      Ultrafast time-resolved spectroscopy of In2 O3 nanowires 

      Tsokkou, Demetra; Othonos, Andreas S.; Zervos, Matthew (2009)
      Ultrafast carrier dynamics in In2 O3 nanowires with an average diameter of ≈100±20 nm grown by the vapor-liquid-solid method have been investigated in detail using differential absorption spectroscopy with femtosecond ...
