9308476 Pejcinovic The proposed research will concentrate on investigating noise in photodetectors: its sources, magnitude, and effect on performance. The research tool for this study is the Monte Carlo method tailored for the simulation of realistic devices. This has the advantage that new device designs do not have to be manufactured before their performance can be examined; instead, their characteristics are simulated on a computer. The Monte Carlo method is a statistical method used to solve the Boltzmann transport equation and noise is directly calculated from the fluctuations of the underlying physical quantities: velocity and number of electrons or holes. The method will first be calibrated on some simple devices and then applied to progressively more difficult and complex cases, including p-i-n photodiodes, avalanche photodiodes, and quantum well infrared photodetectors. The advantages and disadvantages of each design will be examined and possible ways of improving the performance investigated. Since noise can be very sensitive to the details of the physical models used in simulation, this study can also be used to learn more about properties of materials used for photodetectors. ***

9308476 Pejcinovic拟议的研究将集中在调查噪声在光电探测器：它的来源，幅度和性能的影响。 本研究的研究工具是为模拟真实设备而量身定制的Monte Carlo方法。 这样做的好处是，新的器件设计在性能测试之前不必制造，而是在计算机上模拟它们的特性。蒙特卡罗方法是一种用于求解玻尔兹曼输运方程的统计方法，噪声直接从底层物理量的波动计算：电子或空穴的速度和数量。 该方法将首先在一些简单的设备上进行校准，然后逐步应用于更困难和复杂的情况，包括p-i-n光电二极管，雪崩光电二极管和量子阱红外光电探测器。 每种设计的优点和缺点将被检查和可能的方式来提高性能的调查。 由于噪声对模拟中使用的物理模型的细节非常敏感，因此这项研究也可以用于了解更多关于光电探测器材料的特性。 ***
