1Antenna-assisted picosecond control of nanoscale phase transition in vanadium dioxide显示文摘Nanoscale devices in which the interaction with light can be configured using external control signals hold great interest for next-generation optoelectronic circuits.Materials exhibiting a structural or electronic phase transition offer a large modulation contrast with multi-level optical switching and memory functionalities.In addition,plasmonic nanoantennas can provide an efficient enhancement mechanism for both the optically induced excitation and the readout of materials strategically positioned in their local environment.Here,we demonstrate picosecond all-optical switching of the local phase transition in plasmonic antenna-vanadium dioxide(VO_(2))hybrids,exploiting strong resonant field enhancement and selective optical pumping in plasmonic hotspots.Polarization-and wavelength-dependent pump–probe spectroscopy of multifrequency crossed antenna arrays shows that nanoscale optical switching in plasmonic hotspots does not affect neighboring antennas placed within 100 nm of the excited antennas.The antenna-assisted pumping mechanism is confirmed by numerical model calculations of the resonant,antenna-mediated local heating on a picosecond time scale.The hybrid,nanoscale excitation mechanism results in 20 times reduced switching energies and 5 times faster recovery times than a VO_(2) film without antennas,enabling fully reversible switching at over two million cycles per second and at local switching energies in the picojoule range.The hybrid solution of antennas and VO_(2) provides a conceptual framework to merge the field localization and phase-transition response,enabling precise,nanoscale optical memory functionalities.Otto L Muskens Luca Bergamini Yudong Wang Jeffrey M Gaskell Nerea Zabala CH de Groot David W Sheel Javier Aizpurua 2016Light(Science & Applications)2016,5,1:5

3蒙古南部新金斯特地区下泥盆统洛霍考夫阶察甘安布拉格组牙形刺的新记录(英文)显示文摘蒙古南部新金斯特地区萨克黑尔剖面察甘安布拉格组上部发现的牙形刺, 包括Caudicriodusneowos chmidtisp. nov., Caudicriodussp. A, Kimognathussp., “Ozarkodina”planilingua, Pandorinellinaoptima, Ozarkodinaexcavata, 清楚地表明察甘安布拉格组上部应当归到中洛霍考夫阶(泥盆系)而不是像以往那样归到中-上志留统。海相温洛克统和罗德洛统地层在蒙古南部是否存在还需要寻找证据。文章描写了一个新种Caudicriodusneowos chmidtisp. nov.和一个未定种Caudicriodussp. A。王成源 Karsten W EDDIGE Willi ZIEGLER Ch MINJIN 2005古生物学报2005,44,1:2
