A non-destructive form of spectroscopy that analyses solid surface layers chemically by bombarding with electrons and measuring the energy levels of ejected electrons.

plural of scanning transmission electron microscope

A form of transmission electron microscopy in which the sample is held at a very low temperature.

(physics) An electron microscope that transmits a very narrow beam of electrons through a sample; it can detect individual large or heavy atoms.

A micrograph designed to illustrate a sample viewed through a transmission electron microscope.

A microscope designed to contain a sample held at a very low temperature for transmission electron microscopy.

plural of monochromated scanning transmission electron microscope

(electronics) a flat panel display technology that uses surface conduction electron emitters to provide electrons for every pixel. The electrons strike coloured phosphors to produce a colour image. In a general sense, an SED consists of a matrix of cathode ray tubes, each tube producing a single pixel.

(chemistry) Any of several forms of extended covalent bond, deficient in one electron, joining three atoms.

(physics) A scanning transmission electron microscope that is able to focus electrons to a probe of about 0.14 nm and thus distinguish individual atoms.
