Castell, Martin - University of Oxford - Department of Materials

个人简介

I am a Professor of Materials in the Department of Materials and a Fellow of Linacre College at the University of Oxford. I run a research group investigating the atomic scale structure and properties of surfaces and nanostructures. Our main instruments are two ultra high vacuum scanning tunnelling microscopes that can image surfaces at atomic resolution. By characterising and processing surfaces on the nanoscale we aim to create new materials for applications in catalysis, gas sensing, microelectronics, and diverse areas of nanotechnology. Some of our recent work is described on the Group Website. I am a Member of the Institute of Physics (IoP) and hold Chartered Physicist (CPhys.) status. I serve on the Institute of Materials, Minerals & Mining (IoM3) Nanomaterials and Nanotechnology Committee. I lecture the Materials Science undergraduate courses Defects in Crystals (1st year), Surfaces and Interfaces (2nd year), and help to run the Characterisation Module (3rd year). I also give a postgraduate course Microscopy and Analysis of Surfaces. I mainly tutor for St. Edmund Hall.

研究领域

I am interested in the atomic structure of the surfaces of materials, in particular the surfaces of oxide crystals, atomically thin films of oxides on metal substrates, and the networks that form when molecules self-assemble on surfaces. This research is directed at solving problems relevant to catalytic processes and nanotechnology. I am also involved in the development of a sensor for the detection of low concentrations of gas-phase analytes.
