Optical nanotechnology using electrons.
In 1924, Louis-Victor Pierre Raymond, pair of France and Duke of Broglie, astonished his contemporaries in proposing that electrons behave as waves, when moving along spatial dimensions of a few millionths of a milimeters. These distances, dubbed nanometers, remained technologically unaccessible until some decades ago. Roughly speaking, if the electrons appear as waves under these circumstances,
