Computational methods for quantifying surface structure and dynamics with Low-Energy Electron Microscopy

卡迪夫大学的低能电子显微镜-分子束外延系统是独一无二的，可以记录复杂外延过程中发生的关键过程，例如量子点和纳米线的形成。人们常说，一幅图像胜过千言万语，因此记录一部电影所能获得的数据量是前所未有的。半导体纳米结构的电子特性，如量子点和量子线，为当前广泛的技术挑战提供了解决方案，如光伏、光子学、通信等。自组装半导体量子点（QDs）由于其在量子信息技术和纳米光电子学中的潜在应用而受到全世界的关注。目标是通过在外延生长过程中控制单点、分子或纳米线的精确位置来创建先进的量子点结构。该博士生将致力于显微镜的操作和与之相关的数据分析。

The Low Energy Electron Microscope - Molecular Beam Epitaxy system in Cardiff University is unique, enabling the recording of movies of key processes occurring during complex epitaxy, for example quantum dot and nanowire formation. It is commonly said that an image is worth a thousand words, so the amount of data that can be obtained by recording a movie is unprecedented. The electronic properties of semiconductor nanostructures, such as quantum dots and quantum wires, provide solutions for current challenges in a wide range of technologies such as, photovoltaics, photonics, communications, etc. Self-assembled semiconductor quantum dots (QDs) are the subject of world-wide interest because of their potential use in quantum information technologies and nanoscale optoelectronics. The goal is to create advanced QD architectures by controlling the precise position of single dots, molecules or nanowires during epitaxial growth. The PhD student will be devoted to the operation of the microscope and data analysis associated to it.
