I am curious: how would one typically inject charge into diamond?
Could you just deposit a metal electrode on it and have it work

Which reminds me....

"Physicists from the Autonomous University of Madrid and the Madrid
Institute of Advanced Studies in Nano­science have created the
smoothest surface ever made, called a "quantum stabilized atom
mirror," according to the September edition of the research journal
Advanced Materials.
A design for the world's first atomic microscope is in hand, they say.
The mirror resembles a curved wafer. It is made up of a thin
silicon crystal with a thickness of fifty microns, and covered with
a layer of lead a nanometer or two thick. They used A helium atom beam.
without a coating, silicon surfaces have reflected one percent
of helium atoms, but by adding the layer of lead a reflection of up to
67 per­cent was achieved.
The lead is deposited on the silicon at a temperature between
-173º and -133º C . Then, in an 'astonishing and spontaneous' way,
bumps on the surface even out and a super-flat layer emerges."
