Extreme Nanowires: Synthesis, Imaging and Physical Properties
’Extreme Nanowires’ formed by filling single walled carbon nanotubes can be constrained to as little as 3x3, 2x2 and even 1x1 atomic layers in cross section, spanning a single rocksalt unit cell down to an individual row of atoms. As such, these materials represent the smallest ordered size scale possible in terms of scalable nanomaterials fabrication. In some instances these low-dimensional crystal structures form entirely new crystalline forms and often present with profoundly modified physical properties, typically expanded band gap with more highly discretised densities of states and modified optical properties, measurable by Raman Spectroscopy (DOI: 10.1021/nn5023632). Very often, such crystals also undergo ’Phase Change (PC)’ behaviour, morphing from one crystalline form to another, often with a local change in resistivity or conductance with profound implications for memory storage devices (DOI: 10.1021/nl4010354.). Forming nanowires on such small physical scales presents unique and benchmarking challenges for high performance electron microscopy and spectroscopy as these must perform at the level of single atom sensitivity.
You will have an opportunity to contribute to a world-leading experimental project on synthesis and characterisation of Extreme Nanowires by state-of-the-art electron microscopy and other characterisation methodologies, i.e. XPS, solid state NMR and Raman spectroscopy. You will also interact with Warwick’s world class Theory Group (Dr. David Quigley), our Partner Theory Group in Cambridge Physics (Dr. Andrew J. Morris) and also the high performance Raman Spectroscopy group of Professor David Smith of Southampton Physics.
A full 3.5 year studentship for UK students (fees and maintenance) is available. Candidates should hold or expect to hold a 1st (or high 2.1) in Physics or related subject area.
Applications are accepted at any time, but it is likely that interviews will be from later January onwards.
The Physics department is proud to be an IOP Juno Champion and a winner of an Athena Swan Silver Award, reflecting our commitment to equal opportunity and to fostering an environment in which all can excel.
