Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image i… WebTEM specimens were made by standard electro-polishing using a Struers Tenupol-5 applying a 1:2 nitric acid:methanol mixture (T). Electron backscatter diffraction was conducted in a …

WebThis thesis provides the first atomic length-scale observation of the structural transformation (referred to as lattice reconstruction) that occurs in moiré superlattices of twisted bilayer transition metal dichalcogenides (TMDs) at low (θ 2 ̊) twist angles. Such information is essential for the Web15 Jan 2024 · First, the TEM column needs to be maintained at a high vacuum, at least 10 −5 Pa, to minimize undesired electron beam scattering and sample contamination. Secondly, specimens need to be thin enough for electrons to penetrate through, usually of the order of hundreds of nanometres for nanoscale imaging.
