Secondary electron emission (SEE) is a phenomenon where electrons are emitted from a material's surface after it has been struck by incident particles, such as electrons or photons. This process ...

STEM operates by scanning a focused electron beam across the sample and detecting the electrons that are transmitted through it. This scanning process allows for the collection of various signals ...

You hit something with electrons and watch for secondary electron emissions. However, biologists more often use a TEM — a transmissive electron microscope — which passes electrons through a ...
