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

9875051 Vasileska对速度、性能和成本效益的需求不断推动半导体器件走向小型化的极限。在这些未来的超小型器件中，掺杂剂原子的数量和位置的随机微观波动会在大量应该相同的器件中引起电势和场图案的不均匀性，从而导致其阈值电压和漏极电流特性的固有变化。电势波动导致电子进一步被限制到量子点中，自然地将人们从超小型器件的问题带到理解单个和耦合量子点结构中的输运问题。 沿着这些相当令人兴奋的技术趋势，与未来超小型器件的制造相关的困难对计算电子学领域提出了新的要求。在研究方面，将开发各种工具，包括三维蒙特卡罗粒子模拟器、三维薛定谔-泊松解算器和基于非平衡态的二维量子输运模拟器。 绿色函数形式主义。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，将根据其现有的实验数据对开发的工具进行校准。在教育方面，将在课程中引入一门侧重于半导体器件数值建模的本科课程。修订将在现有的研究生水平计算电子类。将通过高级设计和荣誉论文项目的研究包括本科生的独特方式将被追求。一个电气工程实验室将被创建为亚利桑那州立大学的智慧计划内的一般努力的一部分，介绍工程学科的初中和高中女生。为了使现有的模拟工具可用于ASU的实验组，甚至更进一步，将建立一个可通过Web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通用网站。*

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.***
