Early life and education

Oliver studied engineering and materials science at the University of Oxford and completed an industrial placement in metallurgy.[1] Her final year masters project was in optoelectronic materials.[1] She completed her Doctor of Philosophy degree at the University of Oxford in 2003,[3] where she began to work with gallium nitride under the supervision of Andrew Briggs.[1] She used metalorganic vapour-phase epitaxy to grow quantum dots.[1] She spent several months working in an industrial lab in America.[6]

Research and career

She joined the University of Cambridge in 2003 as a Royal Commission for the Exhibition of 1851 postdoctoral research fellow.[1] In 2006 Oliver was awarded a Royal Society University Research Fellowship (URF) at the University of Cambridge.[7] She studied the morphology of gallium nitride light-emitting diodes (LEDs), identifying what factors controlled their efficiency and the impact of defects.[7] She was awarded an Engineering and Physical Sciences Research Council (EPSRC) grant to study semi-polar nitride based structures.[8]

She was appointed a lecturer at the University of Cambridge in 2011.[9] Oliver studies gallium nitride materials for LEDs and laser diodes.[2][4][10] Her research considers ways to engineer the nanostructure of light emitting diodes and how this impacts macroscopic device performance.[10] She has developed atom-probe tomography and scanning capacitance microscopy to study nitride devices.[10]

Oliver is also working on single-photon indium gallium nitride quantum dots for quantum crystallography.[10][11] She has looked at the impact of threading dislocations on the quality factor of InGaN cavities. Her group developed the first blue-emitting single-photon source.[12][13][14] She was the first to note rabi oscillations of GaN quantum dots.[15][16] She designed a quasi-two-temperature growth method to pattern GaN quantum dots, which improved their emission by a factor of ten.[12][17]

Awards and honours

Oliver was elected a Fellow of the Institute of Materials, Minerals and Mining (FIMMM) in 2019.
