STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Over the last 20 years, the proliferation of research utilizing scanning electron microscopy (SEM) has driven the performance of systems towards higher resolution at lower voltages. This enthusiasm is ...

The high sensitivity of the reflection electron microscopy (REM) technique to small changes in the crystal structure and composition of the top surface layers of various crystalline materials makes it ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

Working on the nanoscale for manufacturing poses some unique challenges. While many macroscale manufacturing methods such as lithography and additive manufacturing have been successfully translated ...

In the world of nanotechnology, where structures are measured in billionths of a meter, precise imaging and measurement techniques are essential. Critical Dimension Scanning Electron Microscopy ...

The scanning-electron microscope was used to examine the cortical surface of 123 species of lichens in 12 genera of the lichen family Parmeliaceae. Two general types of cortex were found, one ...
