Carrier dynamics in Β-Ga2O3 nanowires
Othonos, A.; Zervos, Matthew; Christofides, C. (2010)Carrier dynamics have been investigated in Β-Ga2O 3 nanowires (NWs) grown by the vapor-liquid-solid mechanism, using ultrashort transient absorption spectroscopy in conjunction with time-correlating single photon counting ...

The performance of corroded lap splices in reinforced concrete beams
Pantazopoulou, Stavroula J.; Petrou, Michael F.; Spastri, V.; Archontas, N.; Christofides, C. (2017)This article presents the results of an extensive experimental program containing 22 beams with tension lap splices in the central region. The beams were preconditioned under simulated corrosion up to specific levels of ...
