CAREER: Sub-Angstrom Amplitude Atomic Force Microscopy: From Dissipation Imaging to Atomic Manipulation

普通原子力显微镜（AFM）技术在量化纳米级相互作用方面存在一些基本的困难。韦恩州立大学的CAREER项目的目标是应用一种基于光纤干涉测量和非共振、超小振幅操作的新型AFM技术来研究表面上单个原子和分子的纳米力学的重要问题。这包括单个原子和分子的操作，原子尺度的能量耗散，原子键作为控制尖端和表面化学的函数，原子弛豫，以及AFM和扫描隧道显微镜（STM）成像之间的关系。这些问题虽然是根本性的，但对于未来原子/分子尺度纳米系统的合理发展至关重要。与本研究相结合的是一项针对学龄儿童家长的综合外展计划，该计划通过一系列讲座和演示，旨在说明科学研究的兴奋性，并提高他们的孩子对科学职业作为充实职业选择的认识。这项外展计划将与当地学校和两个当地科学博物馆合作进行。纳米技术的未来在于对单个原子和分子的控制。这一崇高的目标只有在我们获得对单个原子和分子力学的扎实知识的情况下才能实现。韦恩州立大学的CAREER项目旨在使用一种新型仪器“亚埃振幅原子力显微镜”来测量操纵单个原子和分子时的力，并对单个原子的“纳米力学”进行补充和重要的实验。这些研究将为未来纳米级器件的设计提供必要的关键知识。研究将涉及韦恩州立大学的研究生和本科生。此外，该项目还包括一个重要的外展组成部分，使当地学生的家长能够深入了解令人兴奋的科学研究，大学研究人员的刺激生活，以及物理学和纳米技术的最新发现。该项目由当地学校和两家科学博物馆提供，旨在提高人们对科学职业的认识，使他们认识到基础科学和应用科学在我们社会中的重要性。

Common Atomic Force Microscopy (AFM) Techniques suffer from a number of fundamental difficulties limiting their usefulness in quantifying nanoscale interactions. The goal of this CAREER project at Wayne State University is to apply a novel AFM technique based on fiber interferometry and off-resonance, ultra-small amplitude operation to study important questions of the nanomechanics of individual atoms and molecules on surfaces. This includes the manipulation of single atoms and molecules, atomic scale energy dissipation, atomic bonding as a function of controlled tip and surface chemistry, atomic relaxation, and the relationship between AFM and Scanning Tunneling Microscopy (STM) imaging. These questions, while of a fundamental nature, are crucial for the rational development of future atomic/molecular scale nanosystems. Combined with this study is an integrated outreach program targeting parents of school age children with a series of lectures and demonstrations designed to illustrate the excitement of scientific research and raise awareness of scientific careers as fulfilling career choices for their children. This outreach program will be conducted in collaboration with local schools and two local science museums. The future of Nanotechnology lies in the controlled manipulation of single atoms and molecules. This lofty goal can only be achieved if we gain solid knowledge of the mechanics of single atoms and molecules. This CAREER project at Wayne State University is designed to use a novel instrument, a "Sub-Angstrom Amplitude Atomic Force Microscope", to measure forces while manipulating single atoms and molecules, and to conduct complementary and important experiments on the 'nanomechanics' of single atoms. These studies will provide crucial knowledge necessary for the design of future nanometer scale devices. Research will involve graduate and undergraduate students at Wayne State University. In addition, the project includes a significant outreach component whereby parents of local school students are provided with an insight into the excitement of scientific research, the stimulating life of a university researcher, and the latest findings in Physics and Nanotechnology. This program, provided through local schools and two local science museums, is designed to raise awareness of scientific careers as fulfilling career choices, and to enlighten the participants about the importance of fundamental and applied science in our society.
