Gas Sensing with AlGaN/GaN 2DEG Channels [PDF]
Procedia Engineering, 2011 AbstractAlGaN/GaN shows great promise as a generic platform for (bio-)chemical sensing because of its robustness and intrinsic sensitivity to surface charge or dipoles. Here, we employ the two-dimensional electron gas (2DEG) formed at the interface of AlGaN/GaN layers grown on Si substrates for the ultra-sensitive detection of NOx.

Instability of 2DEG interacting with drifting 3DEG [PDF]
Semiconductor physics, quantum electronics and optoelectronics, 2008 Dispersion law is studied for high-frequency longitudinal plasma waves in 2DEG (the plane z = 0), separated by thin dielectric layer from half-limited 3DEG. It is shown that drift of 3DEG provokes for special conditions instability of considered plasma waves.
