Research Paper (postgraduate) from the year 2014 in the subject Physics - Optics, University of California, Berkeley, language: English, abstract: The transmission electron microscope is an indispensable tool in science, with applications across medicine, materials science, and geology, among others. However, it is limited in its ability to operate with Zernike phase contrast, a technology commonplace in light microscopy. Zernike phase contrast can be obtained, but only by using carbon-film phase plates or similar methods, all of which are short-lived. Electrons moving close to the speed of...
