What nature of electron beam is used in TEM and SEAD; particle like or wave like?

06 June 2015 1 10K Report

Electron beam is used as particle like or wave like in TEM and SAED but which nature is used in which mode and why?

Many Thanks.

In transmission electron microscopy (TEM) electrons behave as a wave. Like all matter, electrons have both wave and particle properties and their wave-like properties mean that a beam of electrons can be made to behave like a beam of electromagnetic radiation. By using this concept in 1932, successful diffraction (bending of waves around the corners of an obstacle) and normal imaging of an aluminium sheet was achieved.

Could anyone tell me what is the range of submillimeter wave?

There is confusion regarding the submillimeter-wave range. Many papers specify its range from 300GHz but some also consider its range from 100GHz. If I design an antenna on 122ghz what would I...
