摘要

我们报告了金刚石 TeraFET 的 2DEG 沟道在漏极直流电流偏置时产生的亚太赫兹等离子波。我们的数值结果表明，p-金刚石能在室温下支持 300 GHz 的谐振振荡，从而使其发挥亚太赫兹发射器的功能。我们研究了不同沟道长度、栅极偏压、漂移速度和温度对基模振荡的影响。该模型包含了电子散射和电子流体粘度造成的衰减因素。

Current-Driven Terahertz Oscillations in Diamond TeraFET

We report on sub-terahertz plasmonic wave generation in the 2DEG channel of diamond TeraFET when biased by a DC current at the drain. Our numerical results demonstrated that p-diamond can support resonant oscillation of 300 GHz at room temperature, allowing it to function as a sub-THz emitter. We investigated the impact of different channel lengths, gate biases, drift velocities, and temperatures on the fundamental mode oscillation. The model incorporated the decay factors owing to electron scattering and electron fluid viscosity.

期刊介绍： Launched in 1990, the International Journal of High Speed Electronics and Systems (IJHSES) has served graduate students and those in R&D, managerial and marketing positions by giving state-of-the-art data, and the latest research trends. Its main charter is to promote engineering education by advancing interdisciplinary science between electronics and systems and to explore high speed technology in photonics and electronics. IJHSES, a quarterly journal, continues to feature a broad coverage of topics relating to high speed or high performance devices, circuits and systems.
