Career: Computation as a Means of Understanding the Operation of the Devices of the Future

对速度、性能和成本效益的需求继续将半导体器件推向小型化的极限。在这些未来的超小型器件中，掺杂原子的数量和位置的随机微观波动会导致大量应该相同的器件之间的电位和场模式不均匀，从而导致它们的阈值电压和漏电流特性的内在变化。势能涨落导致电子进一步限制在量子点中，自然将人们从超小型器件的问题带入理解单个和耦合量子点结构中的输运的问题。伴随着这些相当激动人心的技术趋势，与制造未来超小型设备相关的困难正在对计算电子领域提出新的要求。在研究方面，将开发各种工具，包括基于3D蒙特卡罗粒子的模拟器、3D薛定谔-泊松解算器和基于非平衡的2D量子输运模拟器。格林的函数形式主义。将与国家实验室(NASA艾姆斯研究中心)建立联系，使我们能够将开发的工具转移到多处理器环境中。通过与工业合作伙伴(英特尔、摩托罗拉)的联系，开发的工具将根据其现有的实验数据进行校准。在教育方面，将在课程中引入一门专注于半导体器件数值建模的本科生课程。将对现有研究生水平的计算电子学课程进行修订。将寻求一种独特的方式，通过高级设计和荣誉论文项目将本科生纳入研究。作为亚利桑那州立大学WISE项目的总体努力的一部分，将创建一个电气工程实验室，将工程学科介绍给初中和高中的女学生。为了使现有的模拟工具可供亚利桑那州立大学的实验小组使用，甚至进一步，将建立一个可通过网络访问的计算中心。为了提高亚利桑那州立大学在基于网络的课程和研究活动方面的知名度，将为亚利桑那州立大学的设备建模小组开发一个公共网站。*

9875051VasileskaThe demand for speed, performance and cost effectiveness continues to push the semiconductor devices towards the limits of miniaturization. In these ultra-small devices of the future, random microscopic fluctuations in the number and location of the dopant atoms induce inhomogeneities in the potential and the field pattern among a large number of what should be identical devices, thus causing intrinsic variation in their threshold voltage and drain current characteristics. The potential fluctuations, which lead to further electron confinement into quantum dots, naturally bring one from the problem of ultra-small devices to the problem of understanding transport in single and coupled quantum dot structures. Along with these rather exciting technological trends, the difficulties associated with the fabrication of the ultra-small devices of the future are putting new demands on the area of computational electronics. .On the research side, a variety of tools will be developed, including 3D Monte Carlo particle-based simulators, 3D Schrodinger-Poisson solvers and a 2D quantum-transport simulator based on non-equilibrium. Green's functions formalism. Links will be established with National Laboratories (NASA Ames Research Center) to enable us to transfer the developed tools to a multi-processor environment. Through links with the Industrial partners (Intel, Motorola), the developed tools will be calibrated on their available experimental data.On the educational side, an undergraduate course that will focus on numerical modeling of semiconductor devices will be introduced into the curriculum. Revisions will be made on the existing graduate level computational electronics class. A unique way of including undergraduate students in the research through senior design and honors thesis projects will be pursued. An Electrical Engineering Lab will be created as part of the general efforts within the ASU's WISE program to introduce the engineering discipline to middle school and high school female students. To make the existing simulation tools available for ASU's experimental groups and even further, a computational hub accessible through the Web will be established. For the purpose of increasing ASU's visibility in terms of web-based classes and research activities, a common Web site for the ASU'S device modeling groups will be developed.***
