Broadband terahertz radiation from a biased two-dimensional electron gas in an AlGaN/GaN heterostructure

The broadband terahertz emission from drifting two-dimensional electron gas (2DEG) in an Al-GaN/GaN heterostructure at 6 K is reported.The devices are designed as THz plasmon emitters according to the Smith-Purcell effect and the 'shallow water' plasma in

报道了在6K温度下，Al - GaN / GaN异质结构中漂移的二维电子气（2DEG）的宽带太赫兹发射。根据史密斯 - 珀塞尔效应以及其中的“浅水波”等离子体，这些器件被设计为太赫兹等离子体发射体。
