Using scanning tunneling microscopy (STM), we demonstrate that oxidation on Pb films is greatly enhanced by atomic Cs catalysts. With only a minute concentration of isolated Cs substitutional atoms in the surface layer (0.004ML coverage), surface oxidation rates are greatly enhanced. First-principles density functional theory (DFT) calculations reveal that a substitutional Cs atom strongly increases...
Die Nano‐Spintronik verfolgt das Ziel, den Elektronenspin in Atomen oder Molekülen nutzbar zu machen, um Bauelemente der Informationstechnologie kleiner, schneller, energieeffizienter, und kompatibel mit nichtflüchtigen Speichern zu gestalten. Unserer Forschungsgruppe an der Universität Hamburg ist es gelungen, ein logisches Gatter zu bauen, das aus nur elf atomaren Spins besteht. Damit wurde ein...
