</span>For that matter Millikan was sensitive to single electrons with his oil-drop experiment – and the school I went to was enlightened enough to let me do this experiment myself at the age of sixteen or so. What is marvelous is that they can make it sound
as though detecting one electron something sexy! Robert Hadfield (in our group) is in the business of detecting single photons and John Weaver (in our group) has huge capability to look at individual electrons with some of his work as well. This stuff is widely
published!</span></div>

I designed a single electron electrometer sensitive at down to about a thousandth of the electron charge. If you look at my Google scholar
page you can find several papers related to this. The device could also be used as a single electron pump, to deliver a stream of electrons phase locked to the frequency of a varying gate potential.<span style=""> </span></span></div><div class="yiv6113172891MsoNormal" style="background:white;" id="yui_3_16_0_1_1429883314197_16594"><span lang="EN-US"><br></span></div><div class="yiv6113172891MsoNormal" style="background:white;" id="yui_3_16_0_1_1429883314197_16594"><span lang="EN-US" id="yui_3_16_0_1_1429883314197_16635">My paper (see attached), looking at the electron sub-structure delivered electrons one-at-a-time and probe the profile of the individual electron wave-function with a resolution of better than a tenth of its de Broglie wavelength.

did not stop when I left the field of course. </span></div><div class="yiv6113172891MsoNormal" style="background:white;" id="yui_3_16_0_1_1429883314197_16594"><span lang="EN-US"><br></span></div><div class="yiv6113172891MsoNormal" style="background:white;" id="yui_3_16_0_1_1429883314197_16594"><span lang="EN-US" id="yui_3_16_0_1_1429883314197_16665">Leo Kouwenhoven, in particular, spent many years investigating my single-electron electrometer device (and creating new ones) in the last quarter of a century. There is now a very great deal of experimental information
about the inner structure of matter, electrons (and photons) with which to work.

framework and secondly get the message out. </span></div>
