Burak Guzelturk

I develop cutting-edge experimental characterization capabilities using extremely bright synchrotron x-ray sources. My goal is to study coupling between lattice and electron dynamics in quantum, photonic and electronic materials. This requires the use of various time-resolved optical and structural techniques to measure dynamics across sub-nanosecond timescales. Our existing capabilities include:

Pump - probe X-ray diffraction (total scattering and WAXS)
Time-resolved X-ray nanodiffraction and microscopy
X-ray induced optical luminescence (time-resolved RL, light yield, spatial resolution)

Field/light-driven manipulation of ferroics
