Images have been computed of closed-shell clusters of 55, 147 or 309 atoms in regular icosahedral and cuboctahedral (f.c.c.) packing for an electron microscope operating at 100 keV, with Cs = 0·7 mm and resolutions of 0·3 and 0·2 nm. The object is to test t...

As you probably know, electrons are the minute charged particles that occupy the outer regions of atoms. (They're also the particles that carry electricity around circuits.) In an electron microscope, a stream of electrons takes the place of a beam of light. An electron has an equivalent ...
the new microscope can identify atoms in its path by a process called electron energy-loss spectrometry. Atoms in the path of the beam absorb energy from some of its electrons to kick their own electrons into higher orbits. The
Single atoms or ions on surfaces affect processes from nucleation1 to electrochemical reactions2 and heterogeneous catalysis3. Transmission electron microscopy is a leading approach for visualizing single atoms on a variety of substrates4,5. It conventionally requires high vacuum conditions, but has been...
450 nm of a-Si was evaporated and QSR-5 was applied for deposition. Lithography was conducted using a scanning electron microscope with a field emission gun at 20 keV and an exposure dose of 5630 µC/cm2. After developing with methyl ethyl ketone, two dry etching mixtures listed in...
After the SRO converged in the sample, a 16 nm initial crack was created in the sample before loading by removing two layers of atoms. During the deformation step, only the z direction is periodic and the other two directions are set at a fixed size. The bottom and top two layers of...
IR transmission spectra were obtained using an infrared Fourier-transform (FT-IR) spectrometer, Optics IFS-125HR, with a Hyperion 2000 microscope (Bruker, Billerica, MA, USA). The photoluminescent (PL) analysis and visualization of the irradiated area were supported by 3D-scanning confocal Raman/...
