CAREER: Energy-Filtered STM: A Novel Technique for Imaging and Spectroscopy of Single Molecules

这个综合教育和研究项目旨在开发扫描隧道显微镜（STM）仪器，通过测量隧道电子的非弹性散射来提供化学特异性，这些电子经历了特定表面化学键排列的能量损失特征。目标是开发一种新的衬底结构，包括一个超晶格能量分析仪，它与半导体材料的STM尖端的开发一起，将使检测非弹性散射载流子和抑制大量背景电子成为可能，这些电子在穿过特定表面吸附分子结构时不会散射。教育项目的重点是学生的研究和设计需要推进STM仪器的发展。建议和指导学生的研究，课程开发和推广，包括通过丹佛自然历史博物馆激发学生和家庭对科学的兴趣，是整体综合研究和教育计划的核心活动。这个研究和教育结合良好的项目将为学生提供原子和分子水平表征和操作的重要领域的培训，为纳米科学和纳米技术服务。这些领域与应用科学和工程高度相关，对提高美国在现代高科技世界中的地位至关重要。在这些领域受过训练的学生将在高强度工业工作的整体竞争中获得显著的优势

This integrated education and research project is aimed at developing scanning tunneling microscopy (STM) instrumentation that will provide chemical specificity by measuring inelastic scattering of tunneling electrons that undergo energy losses characteristic of specific surface chemical bonding arrangements. The goal is to develop a novel substrate structure comprising a superlattice energy analyzer which together with the development of STM tips from semiconductor materials will make possible the detection of inelastically scattered carriers and the suppression of a large background of electrons that do not scatter when they tunnel through specific surface adsorbate molecular structures. The education project focuses on student research and design needed to advance the STM instrumentation development. Advising and mentoring student research, course development and outreach that includes stimulating interest in science for both students and families through the Denver Museum of Natural History are the central activities in the overall integrated research and education plan.%%%This well integrated research and education project will provide student training in an important area of atomic and molecular level characterization and manipulation that serve for nanoscience and nanotechnology. These areas are highly relevant to applied science and engineering, and crucial to advancing the U.S. position in the modern high technology world. Students trained in these areas will gain significant advantages in the overall competition for high-powered industrial jobs.***
