This MWN (Materials World Network) project is a joint research and education activity between West Virginia University and Pontificia Universidad Catolica de Chile (PUC). The project addresses materials science issues involved in the combination of ferroelectric, magnetic and traditional semiconductor nanostructures with devices based on new or enhanced electronic properties achieved through heterostructures. Primary research issues being addressed are: epitaxial growth of high quality materials on semiconductors (or vice-versa), and control of the ferroelectric or magnetic/semiconductor interface. The approach utilizes MBE growth of ferroelectric, magnetic, or other multifunction layers on GaN without exposing surfaces to atmospheric contaminants. The growth apparatus will also be integrated with existing ultra-high vacuum scanning probe microscopy and x-ray photoelectron spectroscopy capabilities. This will permit investigation of initial layer nucleation on GaN and provide information to establish a fundamental understanding of the interface, demonstrate epitaxial growth of ferroelectric layers, and allow integration of magnetic multilayers into such hybrid systems. Other issues being addressed are the effects of molecular adsorption on ferroelectric/semiconductor multifunctional devices. Imaging Raman spectroscopy with sub-micrometer spatial resolution, ellipsometry, x-ray photoemission, spectroscopy, and electric force microsopy, available at the Pontificia Universidad Catolica de Chile (PUC) Physics Department, will be used to probe materials properties on a microscopic level. %%% The project addresses fundamental research issues associated with electronic and photonic materials having technological relevance. An important feature of the project is the strong emphasis on education, stressing integration of research and education, and an international collaboration providing both scientific and educational benefits. The project will establish a strong collaboration with PUC scientists that will include exchange of undergraduate and graduate students between West Virginia University (WVU) and Pontificia Universidad Catolica de Chile (PUC). Undergraduate students will not only actively participate in the research program during the academic year, but will also have the opportunity to spend a significant portion of the summers at PUC, providing them with cultural immersion combined with a serious scientific experience. Graduate students will also participate in the research and will be able to visit PUC to coordinate our laboratory efforts. In the long term, this program will aid WVU in attracting qualified students, and in particular, will reinforce WVU's underrepresented minority outreach efforts, especially those directed toward Latino students. In addition, it will also result in new knowledge that could someday be used to fabricate more efficient electronic sensors and data storage devices.

该MWN（材料世界网络）项目是西弗吉尼亚大学和庞蒂亚大学Catolica de Chile（PUC）之间的共同研究和教育活动。该项目解决了基于通过异质结构实现的新的或增强的电子特性的设备与设备相结合的材料科学问题。要解决的主要研究问题是：高质量材料在半导体（或反之亦然）上的外延生长，以及对铁电或磁/半导体界面的控制。该方法利用了gan上铁，磁或其他多功能层的MBE生长，而无需将表面暴露于大气污染物中。生长设备还将与现有的超高真空扫描探针显微镜和X射线光电光谱能力集成。这将允许研究GAN上的初始层成核并提供信息以建立对界面的基本理解，证明铁电层的外延生长，并允许将磁性多层整合到此类混合系统中。解决的其他问题是分子吸附对铁电/半导体多功能设备的影响。带有亚微米表空间分辨率的拉曼光谱，椭圆法，X射线光发射，光谱和电力微量复制，可在Pontificia Catolica de Chile（PUC）物理学上使用，可用于微观级别的探测材料。 %%％该项目解决了与具有技术相关性的电子和光子材料相关的基本研究问题。该项目的一个重要特征是强调教育，强调研究与教育的整合以及提供科学和教育益处的国际合作。该项目将与PUC科学家建立强有力的合作，其中包括西弗吉尼亚大学（WVU）和Pontificia Universidad Catolica de Chile（PUC）之间的本科生和研究生的交流。本科生不仅将在学年中积极参加研究计划，而且还将有机会在PUC度过很大一部分夏天，从而为他们提供文化沉浸式，并具有认真的科学经验。研究生还将参与研究，并能够访问PUC来协调我们的实验室工作。从长远来看，该计划将帮助WVU吸引合格的学生，尤其是将加强WVU代表性不足的少数派外展工作，尤其是针对拉丁裔学生的少数派外展工作。此外，这还将导致有一天可以用来制造更有效的电子传感器和数据存储设备的新知识。
