A goal in the characterization of supported metal catalysts is to achieve particle-by-particle
analysis of the charge state strongly correlated with the catalytic activity. Here, we …

We report on the development of an ultrafast Transmission Electron Microscope based on a
cold field emission source which can operate in either DC or ultrafast mode. Electron …

Transmission electron microscopy (TEM) offers unprecedent atomic resolution imaging and
diverse characterizations capabilities, which has been proved to be effective in correlating …

Holography relies on the interference between a known reference and a signal of interest to
reconstruct both the amplitude and the phase of that signal. With electrons, the extension of …

Improving our experimental and theoretical knowledge of electric potentials at liquid-solid
boundaries is essential to achieve a deeper understanding of the driving forces behind …

A newly developed carbon cone nanotip (CCnT) has been used as field emission cathode
both in low voltage SEM (30 kV) electron source and high voltage TEM (200 kV) electron …

With the invention of the aberration corrector in electron optics, the spatial resolution in
electron microscopy has progressively improved and has now reached the sub-50-pm …

Reversible ferroelectric domain (FD) manipulation with a high spatial resolution is critical for
memory storage devices based on thin film ferroelectric materials. FD can be manipulated …

The metal-oxide-semiconductor (MOS) capacitor is one of the fundamental electrical
components used in integrated circuits. While much effort is currently being made to …

In this paper, we present the theoretical background to electron scattering in an atomic
potential and the differences between low-and high-energy electrons interacting with matter …
