Transmission electron microscopy (TEM) is a type of electron microscopy that uses a beam of electrons to image the internal structure of a sample with very high resolution. TEM is a powerful tool for studying the microstructure and composition of materials, and it is widely used in materials science, nanotechnology, biology, and many other fields.
TEM works by passing a beam of electrons through a very thin sample, which interacts with the electrons in the beam to produce an image. The electrons that pass through the sample are then focused onto a fluorescent screen or detector, creating an image that reveals the internal structure and composition of the sample at the nanometer scale.
TEM can be used to study a wide range of samples, including materials such as metals, ceramics, semiconductors, and polymers, as well as biological samples such as cells, viruses, and macromolecules. However, in order to be studied with TEM, the sample must be thin enough to allow electrons to pass through it, typically less than 100 nanometers in thickness.
