This proposal was submitted in response to the solicitation "Nanoscale Science and Engineering" (NSF 00-119). The goals of the project are the fabrication, study of physical properties, theory and applications of nanoscale metallic photonic crystals (NMPC). These are structures in which metals are periodically embedded into dielectrics with nanometer size periods. NMPC may carry substantial electrical current but at the same time have transmission bands in the visible/infrared ranges. Some NMPC are also magnetic with important collective spin properties, while others may be superconductors at low temperature with non-linear transport properties. It is planned to fabricate two- and three-dimensional (2D and 3D) NMPC structures, and study their linear and nonlinear optical properties, as well as their transport properties. The surface of low-defect molecular single crystals from the acenes family (such as anthracene, pentacene, etc.) will be patterned into 2D structures, where carrier injection from evaporated metal electrodes will control the resulting device conductivity, metal-insulator transition, plasma frequency and superconductivity properties at low temperature. Theoretical work will guide the experimental research studies. The project is an interdisciplinary collaborative effort among researchers in Physics, Electrical Engineering and Materials Science with collaborators from Honeywell Inc.%%% The project addresses basic research issues in a topical area of materials science, physics, and electrical engineering with high technological relevance. An important feature of the program is the integration of research and education through the training of students in a fundamentally and technologically significant area. The wide range of fabrication, experimental and theoretical physics methods and applications employed throughout the project will enhance the educational opportunities for graduate and undergraduate students. ***

该提案是响应“纳米尺度科学与工程”（NSF 00-119）的征求而提交的。该项目的目标是纳米级金属光子晶体（NMPC）的制备、物理性质、理论和应用研究。在这些结构中，金属以纳米级的周期周期性地嵌入到电介质中。NMPC可以携带大量电流，但同时在可见光/红外范围内具有透射带。一些NMPC还具有磁性，具有重要的集体自旋性质，而其他NMPC可能是低温超导体，具有非线性输运性质。计划制备二维和三维（2D和3D） NMPC结构，并研究其线性和非线性光学性质以及输运性质。低缺陷分子单晶（如蒽、并五苯等）的表面将被图案化成二维结构，其中蒸发金属电极的载流子注入将控制所得到的器件电导率、金属-绝缘体转变、等离子体频率和低温超导性能。理论工作将指导实验研究。该项目是物理学、电气工程和材料科学领域的研究人员与霍尼韦尔公司（Honeywell Inc.）的合作伙伴之间的跨学科合作项目。该项目涉及材料科学、物理和电气工程领域的基础研究问题，具有很高的技术相关性。该计划的一个重要特点是通过培养学生在一个基础和技术上重要的领域的研究和教育的整合。广泛的制造、实验和理论物理方法和应用在整个项目中使用，将增加研究生和本科生的教育机会。＊＊＊
