So let's move on to maybe X-rays and SEM, something like that.

Examples

  • Meanwhile, other SRRC scientists use SEMs not only for cotton research but for projects on rice, peanuts, and corn as well.

  • And then some of the parts that I've taken from the home built SEM are now in this sputtering chamber.

  • Let's take a look at an SEM or scanning electron microscope.

  • And we see all sorts of labels and arrows and SEM inserts.

  • The standard operation of an SEM usually involves incident electron energies of 25 keV.

Surface Forms

SEM singular
SEMs plural

Morphology

SEM = S + E + M

This sense is an acronym of the initial letters in 'scanning electron microscope', so the meaning cannot be inferred compositionally from the letters themselves.

Etymology

SEM is short for scanning electron microscope. Here scanning means 'moving a beam across a surface', electron is a tiny charged particle, and microscope is a tool for seeing very small things, so an SEM 'scans' a surface with electrons to show very fine detail.
