First Observation of Bias Oscillations in GaN Gunn Diodes on GaN Substrate

In this paper, we report on the bias oscillation of GaN-based Gunn diodes realized on a n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> -GaN substrate. Different contact materials, ambient gases, and pulsewidths were used and compared with reg... View More
