Recent Research projects

My research centres upon:

  • Nanowires and Nanotubes: Electronic Devices and Applications :

    Nanowires and nanotubes show pronounced quantum effects in the limit of small diameters, which in the example of carbon nanotubes leads to exceptionally high current density capability along with quantum dot like behaviour. However, to economically use these outstanding properties in large manufacturing volume semiconductor devices, advances are required to reliably and economically control the position, orientation and structure of the nanowires or nanotubes, in a manner that integrates with existing semiconductor devices. Some of my current work involves looking at this through, amongst other methods, surface bound guided growth where nanowires and nanotubes can be guided by predetermined surface topology, for example, on silicon on insulator substrates as used in CMOS devices.

  • Devices and Techniques to Advance Electron Microscopy Instrumentation :

    • Electron Optical Micro-Elements

      Micro- and Nano-fabrication can be used to form electron optical elements such as lenses, that offer particularly small aberration coefficients. These small coefficients coupled with the high sustainable field strengths in micron scale elements, makes electron optical micro-lens particularly suited for low energy electron microscopy (LEEM). Schemes are being investigated to utilize such lenses. Also nanofabrication enables the production of novel vacuum nano-electronic devices, incorporating high brightness electron sources.

    • Design Optimization with Advanced Computational Methods

      Within my work I have developed software and methods to combine current state of art software for electron optics, three-dimensional parametric mechanical computer aided design and electronic device physics simulation, through making use of parallel computation methods.

    • Detectors

      Detectors play an important and high value role in electron microscopy, and many possibilities exist for improving sample-scattered electron collection efficiency along with energy and spatial distribution analysis capability. Some of my work approaches materials accessible within the HCL from the perspective of being a detector.
