PhD position in Nanostructured X-ray detectors


Project Description

This project will use nanofabrication methods to create novel high-resolution X-ray detectors with many orders of magnitude smaller pixel size than existing detectors. Detectors convert high-energy X-ray photons into an electrical signal, and are critical in X-ray systems for clinical and industrial applications. Established bulk detectors have relatively large pixels, which limits the resolution in for instance X-ray microscopy. The project aims at reducing the pixel size of X-ray detectors from the current micrometer size to tens of nanometers.

The student will study the interaction of X-rays with nanostructures, with the aim of developing future high-resolution detectors. In particular, nanowires and other nanostructures will be investigated as X-ray detectors. To this end, the project will create devices in the Lund Nano Lab (http://www.nano.lu.se/facilities/lund-nano-lab-(lnl)/about-lnl), which has world class facilities for nanodevice fabrication. Detectors will be made using electron beam lithography, metal evaporation and other nanofabrication tools. The devices will initially be characterized and optimized using electrical and optical methods. Subsequently, the devices will be tested using nanofocused X-ray beams at the Nanomax beamline at the new MAX IV synchrotron, as well as at PETRA-III in Germany, ESRF in France and possibly other international synchrotron facilities.
