论文摘要
我们展示了一种集合蒙特卡洛（EMC）建模方法，用于在中红外（MID-IR）和Terahertz（THZ）范围内的光伏量子级联检测器（QCD）的稳健和严格模拟。扩展了用于量子级联激光器（QCLS）的现有EMC仿真工具，以模拟在零偏置下热平衡处QCD中的光伏传输效应。在这里，我们介绍了THZ检测器设计的EMC研究的结果，检测波长为84 $μ$ m。仿真结果与实验数据表现出良好的一致性。对于10 K的温度，我们获得9.4 mA/w的峰值响应性。
We demonstrate an Ensemble Monte Carlo (EMC) modeling approach for robust and rigorous simulations of photovoltaic quantum cascade detectors (QCDs) in the mid-infrared (mid-IR) and terahertz (THz) range. The existing EMC simulation tool for quantum cascade lasers (QCLs) was extended to simulate the photovoltaic transport effects in QCDs at thermal equilibrium under zero bias. Here, we present the results of the EMC study of a THz detector design with a detection wavelength of 84 $μ$m. The simulation results show good agreement with experimental data. For a temperature of 10 K we obtain a peak responsivity of 9.4 mA/W.
