Equivalent Circuit Model of Triple-Barrier Resonant Tunneling Diodes Monolithically Integrated with Bow-Tie Antennas and Analysis of Rectification Properties towards Ultra Wideband Terahertz Detections

Abstract

Towards an application for terahertz detector, a monolithic integrated device structure of a triple-barrier resonant tunneling diodes (TBRTDs) with a bow-tie antenna is proposed and its terahertz rectification properties are investigated on the basis of a physics-based equivalent circuit model. A possibility of zero-bias detection is examined owing to nonlinear asymmetric current–voltage characteristics. A possibility of broadband zero-bias detection in terahertz range is suggested for a tentatively designed device structure. A method to analyze rectified signal is established taking the self-bias effect into account.

“…However, in this paper, we analyze the antenna properties by using electromagnetic simulation instead of equivalent circuit analysis towards an accurate investigation of the zero bias detection efficiency and so on. This is the other point which is different from our previous report [6].…”

“…It should also be noted that further consideration for modeling of the TBRTD is nessesarry. For example, the cut off frequency of the TBRTD with quantum capacitance, quantum inductance, other parasitics and the self-bias effect, should be discussed by considering the previouly reported nonlinear model [6,14]. It is useful for detailed analysis of ultimate characteristics and summarizing the rectennna design policy.…”

“…Since the TBRTDs can be designed having asymmetric quantum wells, current flows mainly in forward bias direction, in contrast to DBRTDs. We have started to suggest a analytical method to study terahertz zero bias detection and mixing properties on the basis of an equivalent circuit model, nonlinear I-V characteristics and the consideration of self-bias effects [6]. However, in this paper, we analyze the antenna properties by using electromagnetic simulation instead of equivalent circuit analysis towards an accurate investigation of the zero bias detection efficiency and so on.…”

THz Measurements, Antennas, and Simulations: From the Past to the Future

“…4, modeling the interplay of the antenna with both, sub-THz sources or receivers in the frontend, and the channel describing the environment surrounding the antenna, benefits from both, a simple and insightful antenna representation. On one hand, examples for device-antenna modeling to understand both the THz-generation, as well as desirable operation points, can be found in [60], [61], [62], [63]. Essential system parameters such as, e.g., the equivalent isotropic radiated power (EIRP), can on the other hand be used for channel modeling and system performance evaluation.…”

“…Следует учитывать, что в совокупности ЭП создают электроэнергетическую сеть и обладают емкостью по отношению к заземленной поверхности и относительно друг друга. Поэтому мгновенное значение тока неодинаково вдоль межсоединений (проводники с помощью которых осуществляется запитка ЭП), так как его часть ответвляется в окружающую среду в виде тока смещения [9]. Сами же межсоединения в свою очередь обладают емкостными свойствами и служат направляющими ЭМ-поля.…”
