The principal investigator proposes to solve an issue that arises from a critical need in the success of the next-generation hard drive. The issue involves a technique for measuring temperature at nano-scales on the hard drive, where failure occurs, that has so far not been done. The research partnership involves researchers from industry (Seagate Corporation), University of California - Berkeley's Mechanical Engineering Department and Lawrence Berkeley National Laboratory. Engagement with the Students for Environmental Energy Development (SEED) group at UC-Berkeley and local high schools will be conducted using the existing program. This GOALI project proposes to use photoluminescence nanoparticles to measure temperature at around 10 nm spatial resolutions. Such a high spatial resolution is inspired by the industry's (Seagate) need in a new generation hard drive technology called HAMR (heat-assisted magnetic recording) where the device failure has to do with temperature at nanoscale regions. Preliminary results have demonstrated the potential of the photoluminescence technique for temperature measurement. The spectral shape and lifetime of photoluminescence emission will be correlated as a function of local temperature. Experiments along with modeling will be used to understand HAMR being developed by Seagate, the industrial partner. Although targeting Seagate's HAMR application, these capabilities would be broadly applicable to all sorts of thermal measurement challenges at the nanoscale, including thermal characterization inside a single cell, and of other commercial nanoscale devices such as transistors, memory, or optoelectronics.

首席调查员建议解决下一代硬盘成功的批判性需求引起的问题。 该问题涉及一种用于测量硬盘驱动器上纳米尺度温度的技术，到目前为止，发生故障的情况尚未完成。 研究合作伙伴关系涉及工业研究人员（Seagate Corporation），加利福尼亚大学 - 伯克利大学机械工程系和劳伦斯·伯克利国家实验室。 将使用现有计划与学生与加州大学伯克利和当地高中的环境能源开发（种子）小组的互动。该目标项目建议使用光致发光纳米颗粒在10 nm空间分辨率左右测量温度。 如此高的空间分辨率受到新一代硬盘技术（Hamr（热辅助磁记录）的新一代硬盘技术的需求的启发，该设备与纳米级区域的温度无关。 初步结果证明了光致发光技术对温度测量的潜力。 光致发光发射的光谱形状和寿命将与局部温度相关。 实验和建模将用于了解工业合作伙伴Seagate开发的Hamr。 尽管针对Seagate的HAMR应用，但这些功能将广泛适用于纳米级的各种热测量挑战，包括单个单元内的热表征以及其他商业纳米级设备，例如晶体管，内存或Optoelectronics。
