Overview

OVERVIEW

Research Group: Condensed Matter and Materials Physics

Research Interests

As a member of the Condensed Matter Physics Group, my main research interests lie in magnetic thin films and multilayers, spintronics, and nanoscale thermal transport. At the heart of spintronics is the electron - the ultimate nanomagnet. Consequently, an electron travelling through a magnetic material or in a magnetic field notices the magnetism and is affected by it. Working on the nanoscale it is possible to manipulate the electron with magnets and nanoscale magnetic materials and thereby design new functional magnetic materials with practical uses and to explore the underpinning physics. In contrast to our advanced understanding of electronic transport, understanding of nanoscale thermal transport is in its infancy, limiting our ability to manage heat flow on the nanoscale. There are fundamental challenges in understanding the role of quantum size effects, interfacial resistances and the interplay of phonon and electronic thermal transport. Coupled with these theoretical challenges, there are few methods of experimentally measuring thermal properties with spatial resolution. We have helped to develop thermally sensitive atomic force microscopy (SThM) at York capable of measuring temperature with nanoscale resolution. SThM is a branch of the more mature technique of Atomic Force Microscopy (AFM), which has been used to resolve molecular structure at sub-nanometer scale using an atomically sharp tip. In SThM, the conventional AFM tip is replaced with a thermal probe that is similar to a conventional AFM probe but with a thermally-resistive thermometer thin film deposited at the end of the tip. Hitherto this technique has been qualitative and it is our goal to extract quantitative information to advance the understanding of nanoscale thermal transport.
