Maroon - Re: "How do you count electrons ???? "

One at a time !

Alpha scintillation counters and Solid State detectors - basically large silicon diodes - with very sensitive instrumentation is available.

Many other techniques are also available, even special test structures designed to measure collection using analog techniques integrated with the digtial storage devices.
