XFEL I
- Wojciech Gawelda (Universidad Autónoma de Madrid)
X-ray spectroscopy and scattering allow a unique combination of electronic and structural information to be obtained from a variety of different types of samples in many different forms (solid, liquid, gas). The extension of these methods into the time domain has allowed measurement of dynamic processes, for example the tracking the photoinduced charge carriers in a functional material$^1,^2$...
Nonlinear X-ray wave mixing is a novel area of research that extend the field of nonlinear laser spectroscopy [1] into the short wavelengths regime. Transient grating, a four wave mixing technique, employs two crossed laser beams interacting at the sample to generate an interference pattern. This excitation grating induces dynamics in the sample that transiently changes the index of refraction...
The MID instrument, located in the beamline SASE2 of the European XFEL Facility, has been in operation since 2019. The focus of the MID instrument is ultrafast studies of materials using the High repetition rate and high spatial coherence of the European XFEL accelerator.
The instrument work in a large range of hard x-ray energy ranges from 5 keV to 24 keV. The beam size at the sample...
The interest in copper-indium-sulfide (CIS) quantum dots (QDs), as heavy metal-free nanomaterials, has increased significantly in the past few years. CIS quantum dots (QDs) have been studied for many applications like photodynamic therapy, solar cells, LEDs, and bioimaging [1]. They show exciting optoelectronic properties, such as broad photoluminescence (PL) with a large Stokes shift and long...
The advent of X-ray Free Electron Lasers (XFELs) introduced the possibility to study ultrafast phenomena in the X-ray range, with high temporal resolution and unprecedented peak brightness. This has led to the extension of many established methods into the time-domain as well as the development of new photon-hungry techniques XFELs. These advances have also made it possible to take full...
