Nope, RF electrons don't actually flow. They essentially vibrate in
place. "For a copper wire of radius 1 mm carrying a steady current of
10 amps, the DC drift velocity is only about 0.24 nanometer per
microsecond." At 10 MHz, the electrons would vibrate back and forth at
about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01
nanometer really is so for all practical purposes, electrons don't
flow at all at HF frequencies. Electrons at HF are just a bucket
brigade for the photons that deliver the RF energy to the diode
detector. Unless a circuit is at DC steady-state, photons are
involved, i.e. RF involves photons which constitute the RF fields and
RF waves.
