Question

in SEM back scattered electron are beam of electron that are reflected from the sample by ______ scattering​

Answer 1

Answer:

The signal from secondary electrons tends to be highly localized at the point of impact of the primary electron beam, making it possible to collect images of the sample surface with a resolution of below 1 nm. Back-scattered electrons (BSE) are beam electrons that are reflected from the sample by elastic scattering.
