报告介绍 Abstract:In this talk, I will show that by controlling the distribution and type of defect on these hexagonal sp2-hybridized carbon sheets, one can modify their chemical, magnetic, electronic and mechanical properties that could lead to materials with novel applications. A classification of the various types of defects in graphene-like nanostructures is proposed and their properties will be presente...

报告介绍 We consider optically injected charge and spin currents in semiconductor quantum wells. The injection can be done by quantum optics techniques with the interference of the one- and two-photon transition processes, by intersubband light absorption, and by a stimulated Raman process. The final state with the injected currents strongly depends on the injection process, producing the system very strongl...

报告介绍 Biomimetic systems offer great potential as alternatives to their natural counterparts in a broad range of application areas, e.g. diagnostics/biosensors, catalysis, biomaterials and in separation technologies. Research involving two strategies shall be presented, the first based upon molecular imprinting strategies, and the second nanostructured materials.Despite the phenomenal growth of the field ...

报告介绍 In order to realize the full potential of graphene - an atomic layer of carbon atoms arranged in a hexagonal lattice - the pristine graphene sheet must be modfied so as to display a band gap, at least in certain regions in space. This can be achieved, e.g., by a selective adsorption of adatoms, by cutting the graphene sheet into a nanoribbon, or by applying a transverse electric field to a bilayer g...

报告介绍 Femtosecond (fs) broadband vibrational sum-frequency generation SFG) spectroscopy, where infrared (IR) and visible pulses are combined at an interface, has emerged as a powerful method to probe interfacial molecular dynamics. With fs pulses, a range of vibrational transitions can be probed simultaneously and high time resolution can be achieved. We present examples of energy transfer at surfaces stu...

报告介绍 In this talk I will introduce recent progresses in studying physics of spin-orbit coupling in degenerate atomic gases. Realization of spin-orbit coupled quantum gases opens a new avenue in cold atom physics, and also brings out a lot of new physical problems. In particular, the interplay between spin-orbit coupling and inter-atomic interaction leads to many intriguing phenomena. For instance, in a b...
