Abstract :
We propose InAlAs/InGaAs/InP high electron mobility transistors with an asymmetric chirped dual-grating-gate structure which greatly enhances plasmon instabilities. The fabricated device demonstrates an intense stimulated emission of terahertz monochromatic radiation at cryogenic temperatures for the first time.
