Background. Thermoelectricity (TE) is a unique phenomena allowing to directly convert heat to electric power, and to cool the devices from microelectronic chips to portable fridges. The problem of current thermoelectrics is their low efficiency, although there are no physical limitations for them to reach top Carnot efficiency. At Lancaster, with our collaborators, we recently discovered a gigantic (order of magnitude) increase in thermoelectric (Seebeck) coefficient in one-atom-thick two-dimensional (2D) graphene nanostructures marking a new concept of geometrically defined thermoelectricity that uses geometrical patterning rather than a traditional junction of two materials to convert heat into electrical energy.
The project will use the Lancaster world-class methodology for studying nanoscale thermal and thermoelectric phenomena in the wide range of 2D materials such as graphene, indium selenide, molybdenum disulphide devices, to understand the fundamental science of heat transport and thermoelectricity in these structures. The applications will range from novel thermoelectric devices to heat dissipation in microelectronics that is key obstacle for increase of processors clock speed, delaying Moore’s law by a decade. The work will be performed in close collaboration with leading National Graphene Institute, EU collaborators in 1B€ Graphene Flagship project, and University of Oxford, using the state-of-the-art facilities and interacting with the experimental and theoretical scientists in the field.
The applicant is expected to be a highly motivated PhD candidate to work on this experimental project to work in close collaboration with post-doctoral associate and academics from leading research institutions. The applicant will use unique state-of-the-art advanced scanning probe microscopy and 2D materials processing methodology to characterise novel devices and structures, will work with theorists to build a new understanding of the new phenomena, as well as to explore potential application of new discoveries to key nanotechnology problems. The project will benefit from the full access to the excellent low-temperature measurement and nanofabrication facilities of Lancaster University Physics Department, National Graphene Institute and the state-of-the-art Lancaster IsoLab https://www.lancaster.ac.uk/physics/isolab/
