Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy
The control of optically driven high-frequency strain waves in nanostructured systems is an essential ingredient for the further development of nanophononics. However, broadly applicable experimental means to quantitatively map such structural distortion on their intrinsic ultrafast time and nanometer length scales are still lacking. Here, we introduce ultrafast convergent beam electron diffrac...
متن کاملScanning ultrafast electron microscopy.
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode. Here, we report the development of scanning ultrafast electron microscopy using a f...
متن کاملFour-dimensional ultrafast electron microscopy.
Electron microscopy is arguably the most powerful tool for spatial imaging of structures. As such, 2D and 3D microscopies provide static structures with subnanometer and increasingly with angstrom-scale spatial resolution. Here we report the development of 4D ultrafast electron microscopy, whose capability imparts another dimension to imaging in general and to dynamics in particular. We demonst...
متن کاملPractical Considerations for Ultrashort Electron Pulse Characterization in Ultrafast Transmission Electron Microscopy
In ultrafast transmission electron microscopy (UTEM), extension of the static analytical capabilities of transmission electron microscopy (TEM) to the ultrafast temporal domain relevant for many atomicscale processes allows for direct visualization of non-equilibrium structural phenomena [1]. Analogous to pump-probe spectroscopic techniques, atomic-scale spatiotemporal resolution is accomplishe...
متن کاملDiagnostic Transmission Electron Microscopy
The high resolution and sensitivity of electron microscopy is still a valuable tool, and for some diseases it is the gold standard in pathological diagnosis. Today the sample turnaround time for processing in the lab can be significantly reduced from days to hours by the microwave technology. In urgent clinical cases, microwaveassisted tissue processing, in combination with digital image acquis...
