Princeton physicists have directed the flow of electrons at will using a scanning tunneling spectromicroscope with a rotatable magnetic field. [See image]. “The spectromicroscope has a resolution less than half the size of an atom, allowing it to scan individual atoms and detect details of their electrons while measuring the electrons’ energy and spin distribution.” This capability resulted in the discovery of the tunable electron flow direction. “This level of manipulability opens enormous possibilities for next-generation nanotechnologies and quantum computing.” This report is found here at ScienceDaily…
