Materials Research Laboratory

哈佛大学材料研究实验室(MRL)在三个主要推动领域支持交互式和跨学科的材料研究。相变和失效机制：金属、陶瓷和超导体代表着核心材料科学在相变和超导方面的努力与正在进行的微观力学合作的综合。推力中的活动跨越了一系列材料的尺度，从原子到颗粒，再到多晶体，再到复合材料；这项研究解决了宏观特性和微观结构特征之间的关系。薄膜、界面和表面的重点主要集中在化学和物理之间的联系，并涉及广泛的薄膜材料和结构的基本性质。其中包括液晶膜、聚合膜、自组装单分子膜、液氦膜和液态金属表面形态、表面重建以及约瑟夫森结的二维阵列。一项关于微电子材料的新组织工作涉及具有梯度组成的化合物半导体异质结构的电子性质；外延半导体和液态金属介导的晶体生长的合成和表征的新方法；以及原子传输半导体材料。哈佛大学MRL还支持主要中央研究设施的开发、运营和维护，包括与麻省理工学院MRL合作运营的地面设施。MRL为新教师和与其整体计划相关的材料研究高风险项目提供种子资金。MRL项目目前涉及24名教职员工、8名博士后助理研究员、18名研究生、8名通过本科生研究经验项目的本科生以及7名其他科学和技术专业人员。哈佛大学的MRL是由Henry Ehrenreich教授指导的。//

The Materials Research Laboratory (MRL) at Harvard University supports interactive and interdisciplinary materials research in three primary thrust areas. Phase Transitions and Failure Mechanisms: Metals, Ceramics and Superconductors represents a synthesis of core materials science efforts in phase transitions and superconductivity with ongoing collaborative work in micromechanics. Activities in the thrust span a range of materials scales from atoms to grains to polycrystals to composites; the research addresses the relationships between macroscopic properties and microstructural features. The thrust on Thin Films, Interfaces, and Surfaces focuses primarily on the links between chemistry and physics, and deals with the fundamental properties of a wide range of thin-film materials and structures. These include liquid-crystal films, polymerized membranes, self-assembled monolayers, liquid helium films and liquid metal surface morphologies, surface reconstructions, and two-dimensional arrays of Josephson junctions. A newly organized effort on Microelectronic Materials addresses the electronic properties of compound semiconductor heterostructures with graded composition; novel approaches to synthesis and characterization of epitaxial semiconductors and liquid metal mediated crystal growth; and atomic transport semiconductor materials. The Harvard MRL also supports the development, operation and maintenance of major central research facilities including a surface facility operated in collaboration with the MIT MRL. The MRL provides seed funding for new faculty and for high-risk projects in materials research that are related to its overall program. The MRL program currently involves 24 faculty members, 8 postdoctoral research associates, 18 graduate students, 8 undergraduates through the Research Experiences for Undergraduates program, and 7 other scientific and technical professionals. The Harvard MRL is directed by Professor Henry Ehrenreich. //
