The technology that serves complex modern societies depends to an increasing degree on the discovery and or creation of new materials. The interesting properties of these new materials often depend on the presence of defects and disorder. In particular, we will focus for the next few years on the dilute magnetic semiconductor Ge_(1-x)Mn_x which recent research suggests is ferromagnetic at room temperature and may be integrated with conventional silicon-based electronics. We will also begin studies of ceramic dielectric oxides that may find use as microwave resonators for wireless communications. An important result of the proposed research program will be the training of students to prepare potentially useful ceramics and thin films, to characterize them very well them using widely used and important probes such as x-ray diffraction, energy dispersive x-ray spectroscopy, magnetometry, electrical transport and infrared spectroscopy. With such experience, students will be well-placed to contribute to advanced materials industries. Collaborations have been established with the Tandetron Accelerator Lab at the University of Western Ontario and with several groups at the Brockhouse Institute for Materials Research to supplement the in-house studies.

为复杂的现代社会服务的技术取决于发现和 /或创建新材料的程度。 这些新材料的有趣特性通常取决于缺陷和混乱的存在。 特别是，在接下来的几年中，我们将重点放在稀释的磁性半导体GE_（1-X）MN_X上，最近的研究表明，这在室温下是铁磁，并且可以与常规的基于硅的电子学集成。 我们还将开始研究陶瓷介电氧化物，这些氧化物可能会发现用作微波谐振器的无线通信。 拟议的研究计划的重要结果将是对学生进行培训，以准备潜在有用的陶瓷和薄膜，以通过广泛使用和重要的探针（例如X射线衍射，能量分散X射线光谱，磁力测定法）来很好地表征它们。 ，电运输和红外光谱。 有了这样的经验，学生将有良好的位置为高级材料行业做出贡献。 已经与西安大年份的Tandetron Accelerator实验室建立了合作，并与Brockhouse材料研究所的几个小组进行了合作，以补充内部研究。
