报告介绍 Abstract: 　　The spin Hall eect, i.e., the generation of a transverse spin current from a charge current and viceversa, has attracted much attention in the past decade: it has now become one of the standard tools for the generation and detection of spin currents in magneto-electronic devices. In this talk I address the ques- tion of how the eect manifests itself in the dynamics of collective states...

报告介绍 Abstract: 　　Interfaces between ferromagnetic materials and organic semiconductors ? also known as spinterfaces - constitute an incredibly rich playground in the field of spintronics. For example, spinterfaces have the potential to be implemented as tunable spin filters [1,2], which will pave the way to a whole new class of advanced, i.e., actively controlled spintronics devices. The progress in th...

报告介绍 报告摘要： 　　Thin film semiconductor gas sensors typically operate at temperatures above 400°C, but lower temperature operation is highly desirable, especially for remote area field sensing as this reduces significantly power consumption. We have investigated a range of sensor materials based on both pure and doped tungsten oxide (mainly focussing on Fe‐doping), deposited using both thermal ev...

报告介绍 报告摘要：　　Quantum transport is at the heart of nanoscience and marries a fundamental law of nature, quantum mechanics, with applied electrical engineering and emerging materials technologies. Ultimately, nanoscale electronic devices will contain networks of wires whose cross sections will be so small as to represent quasi one-dimensional conductors with novel transport properties. Among the many...

报告介绍 报告摘要：　　Precision measurements can be performed on hydrogen molecules. Lasers and precision frequency metrology methods can be used to determine the level structure of the smallest neutral molecule to high accuracy. Comparison with the best ab initio calculations, which nowadays cover relativistic effects and quantum electrodynamical effects then provide a test of QED in a system with a molecu...

报告介绍 Abstract：　　FePt and Co/CoO nanoparticles (NPs) were synthesized and assembled on graphene (G) by a solution-phase self-assembly method. The G-NP catalysts showed much enhanced catalytic activity and durability for oxygen reduction reaction (ORR). The G-FePt NPs were more active than the carbon supported FePt (C-FePt) NPs and the commercial C-Pt NPs for ORR in 0.1 M HClO4. The G-Co/CoO showed CoO ...

报告介绍 Abstract: 　　In this talk I will describe results of Hall effect measurements on several systems exhibiting magnetically driven percolative phase transitions. The talk will focus primarily on the semimetallic ferromagnet EuB6, in which we observed a distinctive switch in the Hall resistivity slope in the paramagnetic state. The switching fields in a broad temperature range were found to correspond ...

报告介绍 报告摘要： Graphene-based materials are promising because of their electronic and thermal transport, mechanical properties, high specific surface area, that they can act as an atom thick layer, barrier, or membrane, among other reasons. (Our micromechanical exfoliation approaches conceived of in 1998 yielded multilayer graphene and one paper described in detail how monolayer graphene could be o...

报告介绍 Abstract: Modern biological physics has been significantly advanced recently with rapid developments of various physical techniques and molecular biology methods. Complex biological machinery can be investigated at the most fundamental level and thus molecular mechanisms are elucidated. Here, we present our recent studies of several important biological systems by integrating femtosecond spectroscop...

报告介绍 Abstract:Controlling the shape of colloidal nanocrystals may initially seem like a scientific curiosity, but its implication goes far beyond aesthetic appeal. For nanocrystals made of noble metals, shape not only determines their chemical, plasmonic, and catalytic properties but also their relevance for electronic and photonic applications. Although the first synthesis of colloidal nanocrystals can ...
