The single - atom transistor is made by carving a slot in a hydrogen - coated silicon wafer with a tunneling electron microscope and depositing a single phosphorus atom in the hole. (discovermagazine.com)
«Our decade - long research program had already established the most long - lived quantum bit in the solid state, by encoding quantum information in the spin of a single phosphorus atom inside a silicon chip, placed in a static magnetic field.» (thescienceexplorer.com)
Like many spintronics researchers, University of Sydney physicist Dane McCamey and his colleagues targeted electrons of phosphorus atoms trapped in silicon. (scientificamerican.com)
