Abstract: Nanostructureforests have special features such as tip functions, super-hydrophobicity/hydrophilicity,large superficial areas and enhanced electromagnetic filed, thus they havepotential applications in fields including optoelectronic devices, microfluidicdevices and novel power devices. This talk presents different approaches forfabricating diversiform nanostructure forests, e.g. Oxygen-plasma-stripping-of-photoresist (OPSOP) technique and Gap-induced-uneven-etching (GIUE) technique for nanopillar forests, and a repolymerization-based technique for nanowire/nanofiberforests. Further more, applications of these nanostructure forests inmicrofluidic SERS sensors, MEMS humidity sensors as well as MEMS IR sensors aredemonstrated.

Abstract: Phasechange materials based on Germanium, Antimony and Tellurium (GST) are thought to be the most promising candidates applied in the nextgeneration random-access memory. They have the merits of high physical contrast, fast transfer speed andreliable stability while changing between the memory states. It isbelieved for decades that the memory state is in either amorphous orcrystalline atomic structure. Recently, a new kind of phase change material based on chalcogenide superlattices (CSL)is proposed.In this case, the phase transition is between two crystalline structures,rather than between amorphous and crystalline phases. This would give rise to a newpotential for making an extremely low-power and high-speed memory device.During the presentation, I will introduce the calculation method anddemonstrate how it can be used in the study of phase change materials briefly.

Biography: Xiaoming Yu received his bachelor degree in both Physics and Economicsin Peking University in 2012. He is currently third year PhD student inCambridge University, UK. His research interests involve phase changematerials, memory device and computational physics. He has published two papersand made an oral presentation on MRS spring meeting this year on the phasechange mechanism of Ge2Sb2Te5. Besides theresearch, he is the vice general secretary of Peking University AlumniAssociation in UK and the president of Cambridge University Invelopers Society.He is also dedicated to promote the application of new sensors in the dailylife.

Abstract: ResonatingMEMS are an emerging class of integratable, highly miniaturized,batch manufacturable timing devices that can rival the electrical performanceof well-established quartz-based oscillators. With High quality factor Q, MEMS resonator-based oscillators andfilters entered the sensing and communications arena. Byusing the game-changing MEMS resonating technology, the novel RF MEMS devicescontinue to revolutionize the timing and sensing industry. This talk will introducethe basics of the resonating MEMS devices and some recent advances in high Q, high frequency vibrating MEMS devices as well as its application in future electronicsystems.
