Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

One of the great dream experiments in Science is to directly observe atomic motions as they
occur. Femtosecond electron diffraction provided the first'light'of sufficient intensity to …

Molecular Beam Epitaxy describes a technique in wide-spread use for the production of high-
quality semiconductor devices. It discusses the most important aspects of the MBE …

Complex systems in condensed phases involve a multidimensional energy landscape, and
knowledge of transitional structures and separation of time scales for atomic movements is …

▪ Abstract In this review, we highlight the progress made in the development of 4D ultrafast
electron diffraction (UED), crystallography (UEC), and microscopy (UEM) with a focus on …

With properly timed sequences of ultrafast electron pulses, it is now possible to image
complex molecular structures in the four dimensions of space and time with resolutions of …

Imaging changes in molecular geometries on their natural femtosecond timescale with sub-
Angström spatial precision is one of the critical challenges in the chemical sciences, as the …

Reflection high-energy electron diffraction (RHEED) is widely used to characterize the
surface structure of single crystals. Moreover, RHEED has become a standard tool to …

The electron pulse broadening and energy spread, caused by space charge effects, in a
photoelectron gun are studied analytically using a fluid model. The model is applicable in …
