Education and early life

Flavell was born in Bilston to Maurice and June Flavell. [1] She was educated at Wolverhampton Girls' High School [1] and studied physics (Bachelor of Arts) at the University of Oxford [1] followed by a Doctor of Philosophy degree in 1986. [3] Her doctoral research investigated electron spectroscopy of metal oxides and supervised by P.A. Cox. [3]

Career and research

Flavell joined Imperial College London as a Royal Society University Research Fellow.[ when? ] [6] [7] In 1990 Flavell joined the University of Manchester Institute of Science and Technology (UMIST) in the Department of Chemistry. [6] In 1998 Flavell became the sixth woman in the United Kingdom to be appointed Professor of Physics. [6] She launched a scheme to promote women in science. [8] She was part of the strategy group that designed the 4GLS at Daresbury Laboratory in 2004. [9] [10] She is a member of the University of Manchester Living Lab. [11]

Flavell is interested in using nanoparticles and Quantum dots for efficient fuel cells and new materials for photovoltaics. [12] She works on scanning tunnelling microscopy (STM), X-ray absorption near edge structure (NEXAFS) and extended X-ray absorption fine structure. She has studied titanium dioxide and Tin(IV) Oxide. [13] She is interested in the surface reactivity of nanocrystals and dynamics of charge carriers in solar cells. [14] [15] She attempts to understand how solar cells age at the surface, in efforts to design passivation strategies. [16] Flavell demonstrated that cadmium telluride quantum dots can have near unity quantum yields. [17] In 2014 she served as deputy chair of the physics panel of the Research Excellence Framework (REF). [6] She served on the Council of the Institute of Physics in 2017 [8] and on the Newton International Fellowship committee for the Royal Society. [18] Her research has been funded by the Engineering and Physical Sciences Research Council (EPSRC) and Science and Technology Facilities Council (STFC). [19]

Public engagement

In 2011 Flavell's research group demonstrated their work on quantum dots at the Royal Society Summer Exhibition. [20] [21] [22] She has delivered a Pint of Science talk [23] and discussed the photon on In Our Time in 2015. [24]

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The effect has found use in electronic devices specialized for light detection and precisely timed electron emission.

<span class="mw-page-title-main">Quantum dot</span> Zero-dimensional, nano-scale semiconductor particles with novel optical and electronic properties

Quantum dots (QDs) – also called semiconductor nanocrystals, are semiconductor particles a few nanometres in size, having optical and electronic properties that differ from those of larger particles as a result of quantum mechanics. They are a central topic in nanotechnology and materials science. When the quantum dots are illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy. In the case of a semiconducting quantum dot, this process corresponds to the transition of an electron from the valence band to the conductance band. The excited electron can drop back into the valence band releasing its energy as light. This light emission (photoluminescence) is illustrated in the figure on the right. The color of that light depends on the energy difference between the conductance band and the valence band, or the transition between discrete energy states when the band structure is no longer well-defined in QDs.

<span class="mw-page-title-main">Photoemission spectroscopy</span> Examining a substance by measuring electrons emitted in the photoelectric effect

Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, refers to energy measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies of electrons in the substance. The term refers to various techniques, depending on whether the ionization energy is provided by X-ray, XUV or UV photons. Regardless of the incident photon beam, however, all photoelectron spectroscopy revolves around the general theme of surface analysis by measuring the ejected electrons.

Poly(3,4-ethylenedioxythiophene)-tetramethacrylate or PEDOT-TMA is a p-type conducting polymer based on 3,4-ethylenedioxylthiophene or the EDOT monomer. It is a modification of the PEDOT structure. Advantages of this polymer relative to PEDOT are that it is dispersible in organic solvents, and it is non-corrosive. PEDOT-TMA was developed under a contract with the National Science Foundation, and it was first announced publicly on April 12, 2004. The trade name for PEDOT-TMA is Oligotron. PEDOT-TMA was featured in an article entitled "Next Stretch for Plastic Electronics" that appeared in Scientific American in 2004. The U.S. Patent office issued a patent protecting PEDOT-TMA on April 22, 2008.
