Doping Induced Strongly COrrelated Metal Organic Frameworks

强相关材料是物理学中许多最大的未解谜题的来源，并可能通过强大的量子计算、自旋电子学或超导性，彻底改变信息技术。然而，这些材料处于局域和非局域之间的边界，因此电荷、成分和弱相互作用的微小变化可以使材料在不同状态之间切换：无论是金属、绝缘体还是超导体。因此，实现目标特性需要仔细控制它们的化学计量和相互作用。磁性和电子导电金属有机框架（MECMOFs）的模块化和定向键允许设计传统无机或有机材料中不可能的相互作用和结构。具有高导电性和磁有序温度的MECMOFs的第一个例子刚刚被制作出来，但作为一类新材料，我们的MECMOFs方法工具箱在非化学计量材料的合成和量子性质的测量方面都落后于传统强相关材料。在这个项目中，我们将使用掺杂电荷载流子和配体来将这些强相关MECMOFs转变为一类新的量子材料。强相关材料具有复杂的秩序，结构轨道和自旋，因此我将利用我在衍射和光谱技术方面的专业知识来揭示这些材料中隐藏的秩序。我们还将开发方法来测量掺杂诱导强相关MOFs （DISCO MOFs）的量子特性，使用（in）弹性中子散射的功率和先进的物理特性测量，在现场和压力下。DISCO MOFs将允许我们在MECMOFs中设计奇异的强相关态，如非常规超导体、重费米子态和量子自旋液体，能够解决基本问题并产生转型技术。

Strongly correlated materials are the source of many of the biggest unsolved puzzles in physics and could potentially revolutioniseinformation technology, through robust quantum computation, spintronics or superconductivity. However, these materials lie on theborder between localisation and delocalisation and so small changes in charge, composition and weak interactions can switch amaterial between states: whether metal, insulator or superconductor. Realising target properties therefore requires careful controlover their stoichiometry and interactions. The modularity and directional bonds in magnetic and electronically conducting metalorganic frameworks (MECMOFs) permits design over the interactions and structures impossible in conventional inorganic or organicmaterials. The first examples of MECMOFs with high conductivity and magnetic ordering temperatures have just now been made, butas a new class of materials, our toolbox of methods for MECMOFs lags behind that of conventional strongly correlated materials, inboth synthesis of non-stoichiometric materials and measurement of their quantum properties. In this project, we will use doping withcharge carriers and ligands to transform these first examples of strongly correlated MECMOFs into a new class of quantum materials.Strongly correlated materials have complex orderings, structural orbital and spin, so I will use my expertise in diffraction andspectroscopy techniques to uncover the hidden orders within these materials. We will also develop methods to measure thequantum properties of Doping Induced Strongly COrrelated MOFs (DISCO MOFs), using the power of (in)elastic neutron scatteringand advanced physical property measurements, in field and under pressure. DISCO MOFs will allow us to design in MECMOFs exoticstrongly correlated states, such as unconventional superconductors, heavy fermion states, and quantum spin liquids, able to resolvefundamental problems and produce transformational technologies.
