MRI/Engineering Equipment Proposal: Acquisition of a Multi-user Imaging Ellipsometer

摘要建议编号 CTS-0318241主要研究者： K.斯特贝，约翰霍普金斯大学这笔赠款是用于购买成像椭圆偏振仪。 通过将偏振光照射在表面上并测量反射光束的偏振变化，椭偏仪以埃级分辨率确定固体表面上的膜厚度。成像椭圆偏振法通过将光束聚焦到高分辨率CCD相机上来执行这些测量，以在400 x 500微米的区域上提供1微米的空间分辨率，这种表面拓扑结构的测量在从金膜的溅射波纹到所用聚合物表面上吸附蛋白质膜的演变的学科中是有用的。控制药物释放。因此，这种仪器将推动JHU几个研究小组的研究和教育工作。 来自化学生物分子工程系的本科生和研究生将在纳米技术，表面科学和生物工程的一般领域由co-PI管理的项目中使用成像椭圆偏振仪和材料科学工程。共同首席执行官有有效合作的记录。 三个合作PI已经为化学生物分子工程和材料科学工程部门之间的本科生浓度创建了新的课程。 所有的合作PI都做出了协调一致的努力，以增加妇女和代表性不足的少数民族学生在他们的研究计划的数量。 在本科阶段，学生通过研究项目获得学分，并通过我们的MRSEC和化学生物分子工程部门管理的REU计划进行研究。 通过这些渠道，共同研究所共指导了60名大学生进行研究项目，其中31人是女性，4人来自其他代表性不足的群体。 在博士和研究生一级，妇女和少数民族也被积极录用。 在这些方案中接受培训的妇女和代表性不足群体成员的人数明显体现了这一重点;在30名博士和博士后研究人员中，一半是妇女，两名来自代表性不足的其他群体。购置这些设备将支持共同主持人的研究和外联工作。由主要研究仪器（MRI）计划和界面，运输和热力学计划联合支持

ABSTRACTProposal No. CTS-0318241Principal Investigator: K. Stebe, Johns Hopkins UniversityThis grant is for the acquisition of an Imaging Ellipsometer. By impinging polarized light on a surface and measuring the change in polarization of the reflected beam, ellipsometers determine film thicknesses on solid surfaces with angstrom level resolution. Imaging ellipsometry performs these measurements by focusing the beam onto a high resolution CCD camera to provide spatial resolution of 1micron over areas as large as 400 x 500 microns, allowing for the construction of surface topological maps at that resolution.The measurement of such surface topologies is useful in disciplines ranging from sputter rippling of gold films to the evolution of adsorbed protein films on polymeric surfaces used for controlled drug release. Therefore, this instrumentation will advance research and educational efforts in several research groups at JHU. Undergraduate and graduate students from the departments of Chemical & Biomolecular Engineering will use the imaging ellipsometer and Materials Science & Engineering in projects administered by the co-PIs in the general areas of nanotechnology, surface science and bioengineering. The co-PIs have a record of effective collaboration. Three of the co-PIs have created new courses for an undergraduate concentration between the departments of Chemical & Biomolecular Engineering and Materials Science & Engineering. All of the co-PIs have made a concerted effort at increasing the numbers of women and underrepresented minorities students in their research programs. At the undergraduate level, students are drawn into research via research projects for credit, and via REU programs administered through our MRSEC and in the department of Chemical & Biomolecular Engineering. Through these channels, the co-PIs together have directed 60 undergraduates in research projects, of whom 31 were female and 4 were drawn from other under-represented groups. At the Ph.D and post-graduate levels, women and minorities are also actively recruited. This focus is apparent in the numbers of women and members of under-represented groups being trained in these programs; of the 30 Ph.Ds and postdoctoral researchers, half have been women, and two were drawn from other under-represented groups. The acquisition of this equipment will support the co-PIs efforts in their research and outreach efforts.* Jointly supported by the Major Research Instrumentation (MRI) program and the Interfacial, Transport and Thermodynamics Program
