      Femtosecond carrier dynamics of Inx Ga1-x N thin films grown on GaN (0001): Effect of carrier-defect scattering 

      Lioudakis, Emmanouil E.; Othonos, Andreas S.; Iliopoulos, Eleftherios; Tsagaraki, K.; Georgakilas, A. (2007)
      Ultrafast carrier dynamics in ultrathin Inx Ga1-x N ternary alloys were investigated in detail, using femtosecond transient differential optical absorption measurements. Measurements were performed with probing wavelengths ...

      Magnetic properties of Fe/AlO x/GaAs(001) structures 

      Vaz, C. A. F.; Ionescu, A.; Trypiniotis, Theodossis; Bland, J. A. C.; Dalgliesh, R. M.; Langridge, S. (2005)
      We report results on the effect of the Al Ox barrier layer on the magnetic moment of Fe using polarized neutron reflection. The sample has nominal composition 25 nm Au5 nm Fe1.3 nm Al Ox GaAs (001). The metal deposition ...
