We investigate the possibility of using the n⁺nn⁺ diodes to produce Gunn oscillations. According to our results, we suggest our device as a possible unipolar device for heterodyne detection or emission, since it may act as a detector for terahertz radiation as well as high-frequency local oscillator. For this purpose, we present an investigation of InGaAs n⁺nn⁺ vertical diodes about the presence of high-frequency self-oscillations as well as the effect of mixing induced either by an optical beating or by an electrical excitation in the presence, in both cases, of a dc bias.

自本振等离子体二极管中的外差混合

我们研究了使用 n ⁺ nn ⁺二极管产生 Gunn 振荡的可能性。根据我们的结果，我们建议我们的器件作为外差检测或发射的可能单极器件，因为它可以作为太赫兹辐射的检测器以及高频本地振荡器。为此，我们对 InGaAs n ⁺ nn ⁺垂直二极管进行了研究，研究了高频自振荡的存在以及由光学拍频或电激发引起的混合效应，在这两种情况下情况下，直流偏置。
