Plasmonic gratings for enhanced near infrared sensitivity of Silicon based Schottky photodetectors

Polat, Kazım Gürkan; Aygun, Levent Erdal; Okyay, Ali Kemal (IEEE, 2011)

Schottky photodetectors have been intensively investigated due to their high speeds, low device capacitances, and sensitivity in telecommunication standard bands, in the 0.8μm to 1.5μm wavelength range. Due to extreme cost ...
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 ...
