Scanning electron and transmission electron microscope
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Expert
The SEM or scanning electron microscope has become more admired than the TEM or transmission electron microscope as it can generate images of high resolution, better clarity and three dimensional qualities and needs less sample preparation.
Spin-orbit effect: The effect that causes atomic energy levels to be split since electrons contain intrinsic angular momentum (that is spin) in summation to their extrinsic orbital angular momentum.
Pauli Exclusion Principle (W. Pauli; 1925): No two similar fermions in a system, like electrons in an atom, can contain an identical set of the quantum numbers.
