招CSC(2022)凝聚态物理博士-巴黎六大
|
|
如题，本项目导师是索邦大学的，合作导师是巴黎萨克雷大学的（也就是我导师），两所学校是法国排名前二的公立大学。 导师: vita ilakovac：vita.ilakovac-casses@sorbonne-universite.fr 合作导师: pascale foury-leylekian：pascale.foury@universite-paris-saclay.fr 六大的老师我不太清楚，但是我导师人很好，实验室实力雄厚，只接收csc的学生。 以下是研究基本信息 title of the research project: structure and elemental excitations in multiferoïc organic and metal-organic frameworks thesis supervisor: vita ilakovac, laboratoire de chimie physique - matière et rayonnement, sorbonne university, paris, france co-director pascale foury-leylekian, laboratoire de physique des solides, université parissaclay, orsay, france abstract even if the ferroelectricity and the magnetic order usually appear separately, there are rare compounds, known as multiferroïcs, where the spin and the charge ordering coexist, and sometimes induce each other. the mechanism of their coexistence is one of major questions in today’s materials science. in the case of large magnetoelectric coupling, important applications of these materials can be found in data storage domain, as they offer the possibility to control ferroelectric properties by magnetic fields and magnetism by electric fields. moreover, they are important for the development of sustainable energy sources, like solar cells, as they offer the possibility of efficient ferroelectric polarization-driven carrier separation. the object of the proposed work is to reach a better understanding of the conditions which are necessary to obtain a simultaneous appearance of the magnetic and the charge ordering. the systems we will be interested in are the organic charge-transfer salts, kappa-(bedt-ttf)2x, and metal-organic perovskite-like framework [(ch)3nh2]fe(hcoo)3. we will study their detailed structure and the elemental excitations, like dd-, charge transfer, or collective magnetic and phonon excitations. two experimental techniques will mainly be used: diffraction (x-ray or neutron) and resonant inelastic x-ray scattering (rixs). the interpretation of the experimental data will be supported by ab-initio state-of-the-art electronic structure calculations and simulations of the experimental spectra. 有完整版的pdf，有兴趣的同学可以看看。 链接: https://pan.baidu.com/s/1i81qlqkef8oeqi-sd44w6a 提取码: y45i 复制这段内容后打开百度网盘手机app，操作更方便哦 化学，材料，物理系都可以申请。主要工作为样品合成，结构分析，磁性电性测量。 |
