报告介绍 Electrical energy storage holds the key to wider adoption of renewable energy. Electrical double layer capacitors (or supercapacitors) and Li-ion batteries are two complementary technologies for storing electricity, both involving a working solid/electrolyte interface. Despite their commercialization, some fundamental questions remain unanswered. Supercapacitors store energy as the charge on the sur...

报告介绍 This talk presents the combination of “bottom-up” layer-by-layer (LbL) nano self-assembly and “top-down” micromanufacturing techniques to fabricate MEMS and flexible electronics for biomedical applications. With nano self-assembly and surface micromachining, highly flexible nanoparticle-based cantilever platform for micro sensing and actuation was investigated successfully. W...

报告介绍 Optical antennas or plasmonic antennas are nanoscale metallic structures which act as effective receivers, transmitters and receivers of visible light. Different canonical nanostructures such as metallic nanorings [1], nanorods [2], nanowires [3], dimers [4] or nanoshells [5] are commonly used as optical nanoantennas. These nanoatennas show the ability to focus electromagnetic radiation into tiny sp...

报告介绍 We report the first observation of polarization- and detection angle- dependent spontaneous emission in artificial atoms-semiconductor quantum dots. Using angle resolved white-light transmission spectroscopy we identified local in- and out-of-disc-plane surface plasmon (SP) resonances in the gold array. After depositing CdSe/ZnS (core/shell) nanocrystals on the array, we measured photoluminescence (...

报告介绍 Publishing research in well known scientific journals is one way that researchers build reputation in their community and allow the wide dissemination of their work. This presentation will go through the structure of the article, introduce best practice tips and hints when writing a paper, highlight the editorial process, and detail the main ethical issues that face authors, reviewers, editors and p...

报告介绍 Abstract: In my talk I overview experimental and theoretical investigations of photogalvanic effects induced in graphene and carbon nanotubes. The following items are to be discussed. (i) Photon drag effect induced in single-layer graphene under oblique incidence of the laser light, in the terahertz and infrared frequency regions [1,2]. For the terahertz radiation the photon drag effect can be consi...

报告介绍 报告摘要：Optical microscopy is an essential tool in biological research. However, the spatial resolution of optical microscopy, classically limited by diffraction to several hundred nanometers, is substantially larger than typical molecular length scales in cells, leaving many biological structures unresolvable. We recently developed a new form of super-resolution light microscopy, stochastic optic...

报告介绍 报告摘要：Graphene, the mother of all other graphitic carbons, has demonstrated exceptional physical properties such as high charge carrier mobility, room-temperature quantum Hall effect, good optical transparency and high mechanical and thermal stability, which lead to many prominent electronic applications. Yet, the future research of graphene calls for the efficient chemical synthesis of graphene...

报告介绍 报告摘要：Lithium-ion batteries (LIBs) power millions of laptop computers and other portable electronics. Despite great commercial success, the performance of LIBs based on current electrode materials is approaching its limit. High-energy density and high-power LIBs with greater safety are also vitally important for widespread use of electric cars, which have regained interest recently in view of fa...

报告介绍 Abstract: This talk will be divided into two parts. In the first part, I will show the effect of topological defects on the transport properties of a narrow graphene ribbon. The results show that the conductance vanishes at several discrete Fermi energies where the system develops loop orbital electric currents with certain chirality. The chirality depends on the direction of the applied bias voltag...

报告介绍 Abstract: Three-dimensional topological insulators (TIs) are characterized by their nontrivial surface states in which electrons have their spin locked at a right angle to their momentum under the protection of time reversal symmetry. Topologically ordered phase in TIs does not break any symmetry. The interplay between topological order and symmetry breaking such as superconductivity can lead to new...

报告介绍 Optical forces are generally thought to be too weak for practical use. This picture changes when applied to lightweight nanoscale devices. In this talk, we demonstrate that significant optical force can be produced by a single pass of light in a silicon photonic circuit. This optical force, originated from lateral photon confinement rather than from momentum transfer, is applied in a planar geometry...
