This proposal seeks funding to support Professor Nagarajan Valanoor to spend 3 months (October-December 2010) as a visiting researcher in Queen's University Belfast, and work in collaboration with Professor JM Gregg's nanoscale ferroelectrics activity.Prof Nagarajan is acknowledged internationally as an expert in nanoscale ferroelectrics, with particular expertise in thin film growth, nanoscale patterning and domain imaging using piezo-force microscopy (PFM). His knowledge, experience and interests are strongly aligned with those of the nanoscale ferroelectrics group in Queen's University Belfast (QUB), and his stay in QUB should be extremely useful both in terms of helping to accelerate progress in ongoing research, and in terms of performing preliminary work for potential future collaborative programmes. During his visit, we wish to pursue three themes of common interest:(i) PFM imaging of domain configurations in ferroelectric nanoshapes (contributing to a current EPSRC-funded programme: EP/F004869/1 Investigating the fabrication and dipole characteristics of complex ferroelectric nanoshapes );(ii) Modification of the PFM system at QUB to allow dynamical studies of switching in ferroelectric nanoshapes;(iii) Preliminary exploration of potential flexoelectric polarisation nanodevices.

本提案寻求资金支持Nagarajan Valanoor教授在贝尔法斯特女王大学担任访问研究员3个月（2010年10月至12月），并与JM Gregg教授的纳米级铁电活动合作。Nagarajan教授是国际公认的纳米级专家铁电体，在薄膜生长、纳米级图案化和使用压力显微镜 (PFM) 的域成像方面具有特殊的专业知识。他的知识、经验和兴趣与贝尔法斯特女王大学 (QUB) 纳米级铁电体小组的知识、经验和兴趣密切相关，他在 QUB 的停留对于帮助加速正在进行的研究的进展和执行方面都非常有用。未来潜在合作计划的初步工作。在他访问期间，我们希望探讨三个共同感兴趣的主题：(i) 铁电纳米形状中域配置的 PFM 成像（为当前 EPSRC 资助的项目做出贡献：EP/F004869/1 研究复杂铁电纳米形状的制造和偶极子特性);(ii) 修改 QUB 的 PFM 系统，以便对铁电纳米形状的切换进行动态研究；(iii) 潜在挠曲电极化的初步探索纳米器件。
