Dr. Marc FeldmanECS 0609140This NIRT proposal focuses on nonlinear ballistic transport at room temperature. Ballistic transport is usually considered an aspect of the quantum physics regime, and has been studied intensively at cryogenic temperatures. Nevertheless certain ballistic deflection effects in mesostructures are quite robust at room temperature. An example is the "ballistic rectifier." The ballistic deflection nonlinearity can be used to construct other devices and circuitry operating at room temperature that are very different from conventional circuitry. In this research ballistic deflection devices and circuitry will be fabricated, tested, and analyzed. Simultaneously the physics of nonlinear room temperature ballistic transport will be investigated; and the architectural challenges presented by the unfamiliar requirements and opportunities of circuitry based upon mesoscopic ballistic transport will be explored. This project is ideal for a multidisciplinary approach, in that investigations at the physics, the device, the circuit, and the architectural level are joined to build a "ballistic electronics." Intellectual Merit: of the proposed research is that nonlinear ballistic transport at room temperature, including experimental devices such as the ballistic rectifier, remains poorly understood. Broader Impacts: of specific initiatives on education, on diversity, and on research dissemination, integrated into the research program. The technical focus of this proposal is a realistic area for future practical applications -- room temperature, sub-100 nm device geometry, moderate voltages inducing non-linear transport, and high frequencies. If the predictions of our preliminary model regarding these four issues are borne out, then room temperature BDT circuitry operating at a terahertz and beyond, with very low power requirement, will be suitable for a multitude of applications.

Marc Feldman 博士ECS 0609140此 NIRT 提案重点关注室温下的非线性弹道输运。 弹道输运通常被认为是量子物理体系的一个方面，并且已经在低温下进行了深入研究。 然而，细观结构中的某些弹道偏转效应在室温下相当强大。 一个例子是“弹道整流器”。 弹道偏转非线性可用于构造在室温下运行的与传统电路非常不同的其他设备和电路。 在这项研究中，将制造、测试和分析弹道偏转装置和电路。同时研究非线性室温弹道输运的物理现象；并将探讨基于介观弹道输运的电路的不熟悉的要求和机遇所带来的架构挑战。 该项目非常适合多学科方法，因为将物理、设备、电路和架构层面的研究结合起来构建“弹道电子学”。 智力优点：所提出的研究是，室温下的非线性弹道输运，包括弹道整流器等实验装置，仍然知之甚少。 更广泛的影响：将教育、多样性和研究传播方面的具体举措纳入研究计划。 该提案的技术重点是未来实际应用的现实领域——室温、亚 100 nm 器件几何结构、引起非线性传输的中等电压和高频。 如果我们关于这四个问题的初步模型的预测得到证实，那么在太赫兹及以上频率下运行的室温 BDT 电路，具有非常低的功率要求，将适用于多种应用。
