CL study of blue and UV emissions in ß-Ga_2O_3 nanowires grown by thermal evaporation of GaN [PDF]
, 2011 We report a cathodoluminescence (CL) study of ß-Ga_2O_3 nanowires grown by thermal evaporation of GaN on Si(100) and Au/Si(00) substrates. Condensation and subsequent oxidation of metallic Ga is suggested as the growth mechanism of ß-Ga_2O_3 nanowires ...

Tuning Fano-type resonances in coupled quantum point contacts by applying asymmetric voltages
, 2011 We study the ballistic magnetotransport in a double quantum point contact (QPC) device consisting of a quasi-one-dimensional quantum wire with an embedded island-like impurity - etched nano-hole as in a recently published experiment [J. C. Chen, Y.
