Phys. Rev. Lett. 93, 147402 (2004) [4 pages]Quantum Mechanical Single-Gold-Nanocluster Electroluminescent Light Source at Room TemperatureSee Also: Publisher's Note Received 5 May 2004; published 27 September 2004; publisher error corrected 4 October 2004 Electrically contacted gold-nanocluster arrays formed within electromigration-induced break junctions exhibit bright, field-dependent electroluminescence in the near infrared (650–800 nm). Intensity autocorrelation of spatially isolated individual nanocluster emission driven at high electrical frequency (fac=∼200 MHz) reveals antibunched electroluminescence at room temperature. These results demonstrate the single quantum nature of several-atom gold molecules and suggest their use as room-temperature electrically driven single-photon sources. © 2004 The American Physical Society URL:
