Viewing an active electronic circuit with a scanning electron microscope
Why people recommend it
Ben Krasnow uses a scanning electron microscope to make voltages on a live chip's surface visible, linked when people ask whether electric fields can be seen.
Watch for: Electron beam exposure damages CMOS over time
In their words
You can't see individual electrons actually moving, but you can see the voltages on the surfaces of the circuit!
