Halide perovskites, mechanosynthesis and solid-state NMR
Discovery of new functional materials is one of the key challenges of materials chemistry today. Halide perovskites have recently been discovered as a new class of material for solar cells and light emission. For example, the efficiency of perovskite-based photovoltaics increased from 4% to over 25% in just a decade, and they are now making their way onto the market. Much of this improvement has been thanks to the development of new materials through compositional engineering.
The Kubicki Group (https://kubickilab.wordpress.com/) at the University of Birmingham is pioneering atomic-level structure studies of these new hybrid materials.
Your project will explore a largely uncharted territory in materials research. You will combine mechanosynthesis to discover new materials with high efficiency and throughput (no time-consuming purification involved!). You will then study their atomic-level structure using solid-state NMR and other complementary techniques (X-ray diffraction, optical spectroscopies) to understand how the practically useful properties of the material are related to its underlying structure.
You will use state-of-the-art mechanochemistry and solid-state NMR equipment. Mechanochemistry is exciting because it is by far the most sustainable way of making materials – it has 100% atom efficiency, does not require solvents (no waste!) and many believe it is the future of chemical manufacturing. Solid-state NMR is unique because it allows you to study the atomic-level structure of materials in ways that no other experimental technique can access.
You will also do experiments in a number of large-scale UK research facilities, such as Diamond and the UK High-Field Solid-State NMR Facility – this will be a great opportunity for you to see how such large facilities operate. The experience gained in our group will be useful to you on many levels: you will learn how to do academic research, work with leading experts in materials chemistry, learn how to deliver impactful talks, write academic papers. It will be an opportunity for you to interact with our interdisciplinary network of collaborators worldwide, and become a leader yourself.
If you are passionate about materials chemistry and especially if you consider an academic career in the future, this may be the right opportunity for you.
