The proposed work is a collaborative effort between Towson University and the industrial partner Triton Services Inc. towards developing uncooled microbolometer arrays based on thin films of hole-doped rare earth perovskite manganite materials. Epitaxial manganite thin films will be developed on Silicon, employing lattice engineering schemes, and the properties of these films will be optimized for bolometer operation at or close to room temperature. Single test bolometers and microbolometer arrays will be fabricated and device performance will be evaluated. Intellectual merit: Manganite materials hold potential for superior performance in terms of sensitivity, stability and robustness compared to other bolometer materials currently employed for uncooled IR imaging. Successful demonstration and evaluation of manganite microbolometer arrays will lead to the assimilation of this technology by the IR imaging industry. The proposed effort will generate a knowledge base related to materials manipulation, silicon-integration and device fabrication, which will be useful for other technological applications of the manganites. The materials physics involved in the hetero-epitaxial lattice engineering will contribute to the understanding of oxide hetero-structures and interfaces.Broader Impacts: the proposed effort will enhance the educational experience of the students at Towson University through the industry-university interaction. Graduate students of the recently started professional science masters program will be involved in the proposed work. The industry-university collaboration and student involvement in applied research will serve as a model for other professional science masters programs. Content related to the proposed project will also be incorporated in K-12 STEM outreach activities at Towson University.

拟议的工作是陶森大学与工业合作伙伴Triton Services Inc.之间的合作努力，以基于基于孔掺杂的稀有稀土钙钛矿锰矿材料的薄膜开发未冷却的微量仪阵列。外延锰矿薄膜将在硅上开发，采用晶格工程方案，这些膜的性能将在室温下或接近室温下进行优化，以实现重量计操作。将制造单个测试验证仪和微量线计阵列，并评估设备性能。智力优点：与目前用于未冷却的IR成像的其他钢计材料相比，锰矿材料在敏感性，稳定性和鲁棒性方面具有出色的性能。成功的演示和评估锰矿微光仪阵列将导致IR成像行业对这项技术的同化。拟议的工作将产生与材料操纵，硅整合和设备制造有关的知识基础，这将对锰矿的其他技术应用有用。杂型晶格工程中涉及的材料物理学将有助于理解氧化物异源结构和接口。Broader的影响：拟议的努力将通过行业 - 大学的互动来增强陶森大学学生的教育经验。 最近开始的专业科学硕士课程的研究生将参与拟议的工作。工业大学的合作和学生参与应用研究，将成为其他专业科学硕士计划的典范。与拟议项目有关的内容也将纳入陶森大学的K-12 STEM外展活动。
