Site-selective substitutional doping with atomic precision on stepped Al (111) surface by single-atom manipulation

In fabrication of nano- and quantum devices, it is sometimes critical to position individual dopants at certain sites precisely to obtain the specific or enhanced functionalities. With first-principles simulations, we propose a method for substitutional doping of individual atom at a certain position on a stepped metal surface by single-atom manipulation. A selected atom at the step of Al (111)...

Toward Understanding Automotive Exhaust Conversion Catalysis at the Atomic Level

This review focuses on the reactions and catalysts used for control of emissions of exhaust gases for gasoline-fueled automobiles with emphasis on fundamental understanding of the surface processes. Attention is paid to three-way catalysts, which simultaneously enhance the conversion of CO, hydrocarbons, and nitrogen oxides. The mechanisms of the CO oxidation and nitrogen oxide reactions, the s...

Coherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of Λ-Type Three-level Atomic Ensembles

In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel Λ-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achieva...
