One of the most important steps towards future quantum photonics will be the versatile generation of single photons or entangled photon pairs on demand. The goal of the research project is the development of a single photon source based on electrically pumped single organic molecules. Electroluminescent molecules will be incorporated into thin organic films or organic nanocrystals. Nanocrystals of some 10 nm diameter will be generated via rapid sublimation or a dewetting technique. The most challenging issues will be the fabrication of electrodes with the capability to accurately control the charge injection and the reduction of the recombination volume. In an alternative approach, electroluminescence will be generated via a STM, either from thin molecular films or from molecules deposited on a surface. From a more fundamental point of view, new insight into one of the most pressing problems in organic electronics is expected: trapping of charge carriers by defects, especially at the organic-metal interface.
