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 ...

Investigation of Different Si(111) Surface Preparation Methods for the Heteroepitaxy of GaN by Plasma-Assisted MBE
Androulidaki, M.; Georgakilas, A.; Peiro, F.; Amimer, K.; Zervos, Matthew; Tsagaraki, K.; Dimakis, M.; Cornet, A. (2001)The in-situ low temperature preparation of hydrogen passivated Si(111) surfaces has been investigated for GaN growth by rf-plasma source molecular beam epitaxy. The GaN/Si heterostructures were analyzed by transmission ...
