Materials Research Science and Engineering Center: Oxide Thin Films, Probes and Surfaces

马里兰大学材料研究科学与工程中心(MRSEC)致力于解决与铁电动力学和表面纳米结构有关的基本问题，以及与高度自旋极化的磁性氧化物的性质有关的问题。MRSEC支持有效的大学前教育外展努力，其中包括为中学女生提供的暑期科学计划，以及实际操作的数学和理科学生计划。该中心为向大量工业和联邦实验室转移知识开展了密集的活动。MRSEC还通过种子资金支持有前途的新项目，并开发和维护共享的实验设施。拟建中心的研究分为三个跨学科研究小组(IRG)。IRG 1，铁电薄膜中的极化动力学，解决了允许控制和优化铁电薄膜随时间变化的行为的关键材料问题，以及目前限制其在计算机存储器、传感器和执行器中的应用的关键材料问题。IRG 2，表面纳米结构：从波动到驱动系统，建立在这组研究人员开发的强大的实验和理论工具的基础上，预测各种工艺条件下薄膜的表面结构演变，包括化学气相沉积生长和电迁移。IRG 3，具有高自旋极化的金属氧化物，专注于限制具有高自旋极化的金属氧化物的发展，这些金属氧化物可用于磁性设备，包括自旋电子学和磁性传感器。中心参与者包括23名高级研究员、8名博士后助理、20名研究生、10名本科生和2名支持人员。艾伦·D·威廉姆斯教授是MRSEC的负责人。

The Materials Research Science and Engineering Center (MRSEC) at the University of Maryland addresses fundamental problems connected with the dynamics of ferroelectrics and of surface nanostructures, and with the properties of highly spin polarized magnetic oxides. The MRSEC supports an effective pre-college education outreach effort that includes summer science programs for middle school girls and hands-on math and science student programs. The Center has intensive activities for knowledge transfer to a large number of industrial and federal laboratories. The MRSEC also supports promising new projects through seed funding, and develops and maintains shared experimental facilities. Research in the proposed Center is organized into three Interdisciplinary research Groups (IRG). IRG 1, Polarization Dynamics in Ferroelectric Thin Films, addresses key materials issues that will allow to control and optimize the time-dependent behavior of thin film ferroelectrics, and that currently limit their applicability to computer memories, sensors and actuators. IRG 2, Surface Nanostructures: From Fluctuations to Driven Systems, builds upon powerful experimental and theoretical tools developed by this group of investigators to predict the surface structural evolution of films under various processing conditions, including chemical vapor deposition growth and electromigration. IRG 3, Metal Oxides with High Spin Polarization, focuses on issues limiting development of metallic oxides with high spin polarization that can be utilized in magnetic devices, including 'spintronics' and magnetic sensors. Center participants include 23 senior investigators, 8 post-doctoral associates, 20 graduate students, 10 undergraduates and 2 support personnel. Professor Ellen D. Williams directs the MRSEC.
