Graphene as Positronium aka Flann O'Brien's Omnium

the positron becomes trapped in an image potential well at the surface before annihilation.
We report a detailed line shape analysis of the positron induced C KVV Auger line shape from highly oriented pyrolytic graphite (HOPG) and a single layer of graphene grown on polycrystalline Cu.

 ALPHA stored atoms of antihydrogen, consisting of a single negatively charged antiproton orbited by a single positively charged anti-electron (positron). While the number of trapped anti-atoms is far too small to fuel the Starship Enterprise’s matter-antimatter reactor, this advance brings closer the day when scientists will be able to make precision tests of the fundamental symmetries of nature. Measurements of anti-atoms may reveal how the physics of antimatter differs from that of the ordinary matter that dominates the world we know today.
O.K. so I guess you need anti-protons along with anti-electrons for positronium ... but positrons are a good first start.

each firing results in the production of quadrillions of positrons—a density level comparable to those produced at CERN. The researchers suggest their device could be used to mimic the from and/or pulsars, hopefully offering some answers to questions such as,
fired a at a sample of inert . Doing so caused the creation of a stream of electrons moving at very high speed. Those electrons were directed at a very thin sheet of metal foil which caused them to smash into individual .
Yeah it seems Graphene is a much better was of producing positrons.

Hybrid boron nitride-graphene nanostructures could enable fuel cell cars

 positron energy?

pillars in boron nitride graphene make space for hydrogen atoms

 proton energy....
