Scanning transmission low-energy electron microscopy
We discuss an extension to the transmission mode of the cathode-lens-equipped scanning electron microscope, enabling operation down to the lowest energies of electrons. Penetration of electrons through free-standing ultrathin films is examined along the full energy scale, and the contribution of the secondary electrons (SEs), released near the bottom surface of the sample, is shown, enhancing t...
متن کاملForeword to the special issue low-voltage electron microscopy.
Today, low voltage electron microscopy is a topic of high relevance all over the world; in Japan [1], America [2], and Germany [3] particular research projects are even dedicated to unravel the atomic and electronic structure of radiation sensitive matter with 60 kV electrons and below. It seems that research comes back to its voltage-routes of the early days of electron microscopy, when in 193...
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...
متن کاملConventional transmission electron microscopy
Researchers have used transmission electron microscopy (TEM) to make contributions to cell biology for well over 50 years, and TEM continues to be an important technology in our field. We briefly present for the neophyte the components of a TEM-based study, beginning with sample preparation through imaging of the samples. We point out the limitations of TEM and issues to be considered during ex...
متن کاملTransmission electron microscopy of nanomaterials
Transmission electron microscope (TEM) has emerged as a very powerful tool for probing the structure of metals and alloys because of its capability to provide morphological information, crystallographic details, and chemical composition of phases distributed on a very fine scale in a given microstructure. Convergent beam electron diffraction, nano or micro beam diffraction and selected area dif...
