Biography

Dr Ming Li obtained his Ph.D. in 2008 from the Department of Materials Science and Engineering at the University of Sheffield under the supervision of Professor Derek C. Sinclair. Upon completing his Ph.D., he remained in Sheffield working as a Postdoctoral Research Associate (PDRA) with Professor Sinclair until 2013. He then joined the group of Professor Matthew J. Rosseinsky FRS as a PDRA at the Department of Chemistry, University of Liverpool. In 2014 he was awarded a Nottingham Research Fellowship and started his independent academic career at the University of Nottingham.

Dr Ming Li is part of the Advanced Materials Research Group.

Current Research

Our research focuses on understanding electrical conduction mechanisms and defect chemistry in functional materials (mainly metal oxides) to design and manufacture new materials for energy and electronic applications.

Our particular expertise and the core theme underlying our research is probing the 'electrical microstructure' and defect chemistry of materials using various electrical characterisation techniques, particularly Impedance Spectroscopy. Metal oxides often exhibit low levels of nonstoichiometry (typically <1 at%) that is associated with impurities in raw materials, deliberate chemical doping or 'accidental' element loss/gain during sample processing. Such small compositional variations, although difficult to detect accurately by common chemical techniques, can induce significant changes in electrical conduction mechanism and conductivity as well as complex electrical inhomogeneity in a sample. We specialise in separating contributions to conductivity and permittivity from different regions (grains, grain cores, gran shells, grain boundaries, sample-electrode non-ohmic interfaces, surface layers, etc.) and identifying the nature of charge carriers (electrons, holes, ions, etc.) using Impedance Spectroscopy.

This approach and expertise allow for deep understanding of composition-structure-property relationships in metal oxides, which is crucial to design new materials as well as improve the performance of current materials.
