Research:Our research studies single nanostructure devices using coherent X-ray imaging and X-ray diffraction. In particular, we're developing techniques for investigations that combine hard X-ray imaging and X-ray diffraction with electrical measurements [3,5]. Hard X-rays can penetrate through thick samples, allowing measurements of devices in operando. The X-rays can both be used as a pump, to study for instance X-ray induced electrical conductance [5], or as a probe of the structure in nanodevices [3]. Nanowires have demonstrated much stronger response to hard X-rays than expected from bulk data [5]. We have shown that the shape of bent nanowires can be reconstructed in 3D with nanometre precision [2,3].The image below shows a 3D reconstruction of a nanowire changing shape under the influence of a strong electric field [3].  The experiments require intense nanofocused X-ray beams that are only available at synchrotrons such as Petra-III and ESRF, and now also at MAX IV. The image below shows a recent ptychographic reconstruction from the Nanomax beamline at the new MAX IV synchrotron, depicting a standing GaInP nanowire (courtesy Vilgaile Dagyte and Magnus Borgström).  We have simulated the heating from pulsed X-rays using the finite-element software Comsol [1]:  For an updated lists of publications, please see ResearcherID or Google Scholar.
