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

这一综合性教育和研究项目旨在开发扫描隧道显微镜(STM)仪器，该仪器将通过测量隧道电子的非弹性散射来提供化学特异性，隧道电子经历特定表面化学键合安排的能量损失特征。我们的目标是开发一种包括超晶格能量分析器的新型衬底结构，该分析器与半导体材料的STM尖端的开发将使检测非弹性散射载流子和抑制电子的大背景成为可能，当电子通过特定的表面吸附分子结构时不会散射。该教育项目侧重于推进STM仪器开发所需的学生研究和设计。为学生的研究、课程开发和推广提供建议和指导，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，是整个综合研究和教育计划的中心活动。这个完美整合的研究和教育项目将在原子和分子水平表征和操纵的一个重要领域为纳米科学和纳米技术的学生提供培训。这些领域与应用科学和工程高度相关，对提升美国在现代高科技世界的地位至关重要。在这些领域接受培训的学生将在争夺高性能工业工作的整体竞争中获得显著优势。*

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.***
