This Nanoscale Exploratory Research (NER) proposal was submitted in response to the solicitation "Nanoscale Science and Engineering" (NSF 01-157). The goal of the project is to form superlattice nanostructures using electrochemical atomic layer epitaxy (EC-ALE). EC-ALE is based on surface limited electrochemical reactions, and is complementary to traditional techniques such as MBE and VPE, with the possibility of deposition on odd-shaped surfaces such as tubes, and strongly reduced diffusion, since the process takes place at room temperature. Specific research objectives are: 1. Growth of compound semiconductor superlattices. 2. Electrodeposition of compounds on nano array electrodes. 3. Growth of superlattice nanocrystals. 4. Studies of delta doping. The impact and significance of this project may be summarized as follows. There is a strong demand for increased package density of electronic structures, combined with a trend to electrochemical processes for production in the chip industry. The search for improved optoelectronic materials, like photovoltaic cells and infrared detectors is actively pursued in both the private and government sector. On the scientific front, the interest in nanostructured materials continues to rise, based on the large parameter-space available to engineer novel materials. EC-ALE offers unique approaches to the deposition of nanoscale structures, and access to materials that cannot readily be produced by MBE or VPE. The proposed project relies on both the deposition and characterization of nanostructured semiconductors. A cross-disciplinary approach is taken, combining aspects of Chemistry and Physics. %%% The project addresses basic exploratory research issues in a topical area of materials science 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 project is co-supported by the MPS/DMR and MPS/CHE Divisions.***

该纳米级探索性研究(NER)计划是应“纳米级科学与工程”(NSF 01-157)的征集而提交的。该项目的目标是利用电化学原子层外延(EC-ALE)形成超晶格纳米结构。EC-ALE基于表面有限的电化学反应，是对MBE和VPE等传统技术的补充，可以沉积在管子等奇怪形状的表面上，并且由于该过程在室温下进行，因此大大减少了扩散。具体研究目标为：1.化合物半导体超晶格的生长。2.在纳米阵列电极上电沉积化合物。3.超晶格纳米晶的生长。4.增量掺杂的研究。该项目的影响和意义可以概括如下。在芯片工业中，存在对增加电子结构的封装密度的强烈需求，以及用于生产的电化学工艺的趋势。私营部门和政府部门都在积极寻求改进的光电材料，如光伏电池和红外探测器。在科学方面，基于可用于设计新材料的大参数空间，对纳米结构材料的兴趣继续上升。EC-ALE提供了沉积纳米级结构的独特方法，并提供了使用MBE或VPE无法轻易生产的材料的途径。拟议的项目依赖于纳米结构半导体的沉积和表征。采取了跨学科的方法，将化学和物理的各个方面结合起来。该项目解决了材料科学中具有高度技术相关性的主题领域中的基本探索性研究问题。该计划的一个重要特点是通过在一个具有根本意义和技术意义的领域对学生进行培训，将研究和教育结合起来。该项目由MPS/DMR和MPS/CHE两个司共同支持。*
