Direct evidence for the instability and deactivation of mixed-oxide systems: influence of surface segregation and subsurface diffusion

Emmez, E.; Vovk, E. I.; Bukhtiyarov V. I.; Ozensoy, E. (2011)

In the current contribution, we provide a direct demonstration of the thermally induced surface structural transformations of an alkaline-earth oxide/transition metal oxide interface that is detrimental to the essential ...
Variable temperature-scanning Hall probe microscopy with GaN/AlGaN two-dimensional electron gas (2DEG) micro Hall sensors in 4.2-425 K range using novel quartz tuning fork AFM feedback

Akram, Rizwan; Dede, Münir; Oral, Ahmet (IEEE, 2008)

In this paper, we present the fabrication and variable temperature (VT) operation of Hall sensors, based on GaN/AlGaN heterostructure with a two-dimensional electron gas (2DEG) as an active layer, integrated with quartz ...
