AbstractECCS-0746757Ian Appelbaum, University of DelawareThe objective of this research is to experimentally understand the necessary device physics concepts required for development of Silicon-based spintronics. This is motivated by the need to demonstrate a scheme for electronic logic processing alternative to the presently-used charge-based physical paradigm now reaching its scaling limits. The approach is to use spin-polarized hot-electron techniques for spin detection in an ultra-high-vacuum wafer-bonded Silicon device structure.Intellectual Merit of the proposed activity flows from the use of hot-electron techniques to circumvent prohibitive limitations for spintronics devices made from Silicon. This allows experimental exploration of the fundamental spin transport and materials parameters to enable Si spintronics.Broader Impacts of the research component are derived from leveraging the existing technological and economic infrastructure of Si-based electronics to extend performance trends of our present technology with Si spintronics. The advantages afforded by spintronics devices enabling lower-power, instant-on electronics will allow increased device portability and are especially important in light of today?s increasing energy costs and its environmental impact. The Broader Impacts of the integrated educational and outreach component are achieved through training graduate students (including those underrepresented in engineering) in diverse aspects of science and engineering including semiconductor device design, processing, measurement, and spintronics ? all these are essential for an increasingly technology-based economy.

ian Appelbaum，特拉华大学，本研究的目的是通过实验了解硅基自旋电子学发展所需的必要器件物理概念。这是由于需要展示一种电子逻辑处理方案，以替代目前使用的基于电荷的物理范式，现在已经达到其缩放极限。该方法是利用自旋极化热电子技术在超高真空晶圆键合硅器件结构中进行自旋检测。所提出的活动的智力价值来自使用热电子技术来规避由硅制成的自旋电子学器件的限制性限制。这允许对基本自旋输运和材料参数进行实验探索，以实现硅自旋电子学。研究组件的更广泛影响来自于利用现有的硅基电子技术和经济基础设施，以扩展我们现有的硅自旋电子学技术的性能趋势。自旋电子学器件提供的低功耗、瞬时电子器件的优势将增加器件的可移植性，这在当今尤为重要。美国不断增加的能源成本及其对环境的影响。通过在科学和工程的各个方面（包括半导体器件设计、加工、测量和自旋电子学）培训研究生（包括那些在工程领域代表性不足的研究生），实现综合教育和推广部分的更广泛影响。所有这些对于日益以技术为基础的经济都是必不可少的。
