With the current technology, can an electron be separated separately? Control it in a small area, or move in the direction we set?

At a very high temperature, the gaseous substance expands to a certain limit when heated, and the electrons break away from the atoms, which become a charged plasma. At this time, the electrons are released and exist independently. So can such electrons be separated one by one? Has anyone done this and how?

 

[Ssssssss]

That's pretty much what an electron gun does it just heats up a filament and strips its electrons with an electric field.

Control it in a small area...

Volume.

A professor dinged me once for saying "area" when I meant "volume". Science gotta be precise.

I might have gotten away with "region".

electrons can be emitted one by one.

Electrons or polarised particles ?

What is the difference ?

Yes. Electron guns have been around for decades.
