About the Project
Terahertz (10^12 Hz, THz) pulsed imaging is a new technique with high spatial resolution (about 20 μm) and has only emerged recently as a potential imaging tool. It is a totally non-destructive and non-ionising imaging modality. Potential applications range from materials characterisation, to security and medical diagnosis, but the analysis and instrumentation needs to be tailored for each application investigated.
In the first stage of this project, the student will develop methods and devices to speed up terahertz data acquisition. Analysis techniques and algorithms will be established for improved sample characterisation and image contrast. This will be relevant to many applications of terahertz technology and will be of interest to our industrial partners and material science collaborators. The enhanced capabilities will then be used by the student in new spectroscopy and imaging applications. For example, the group has recently developed a graphene-based modulator of terahertz radiation (see Figure and Ref. [1]). This offers exciting new prospects for THz modulation and the non-invasive characterization of 2D materials that exhibit exotic electronic properties.
Prof. MacPherson has recently joined Warwick University and received a Wolfson Merit award to support her research in the UK https://www2.warwick.ac.uk/giving/health/cancer/. For more background information regarding Prof. MacPherson’s research interests, please see her Hong Kong Group web page http://bme.ee.cuhk.edu.hk/thzgroup/. For further information do not hesitate to contact Prof. MacPherson directly on [Email Address Removed].
The student will be enrolled on the Materials Physics Doctorate scheme, giving access to a tailored research degree to help you exploit our own outstanding materials growth, fabrication, characterisation and computational capabilities, and those at central facilities. See http://go.warwick.ac.uk/MPDOC for more details.
