Webb13 jan. 2024 · The team discovered that the kinetic energy of the atom as it ploughs into the silicon crystal and dissipates its energy by friction can be exploited to make a tiny electronic ‘click’. Professor Jamieson said the team could “hear” the electronic click as each atom dropped into one of the 10,000 sites in the prototype device. Webb4 maj 2024 · People have made small heat engines before using a single atom, a single molecule and defects in diamond. A key difference about this device is that it shows quantumness in its action. "We want...
