1Fano resonance boosted cascaded optical field enhancement in a plasmonic nanoparticle-in-cavity nanoantenna array and its SERS application显示文摘Cascaded optical field enhancement(CFE)can be realized in some specially designed multiscale plasmonic nanostructures,in which the generation of extremely strong fields at nanoscale volume is crucial for many applications,for example,surface-enhanced Raman spectroscopy(SERS).In this paper,we propose a strategy for realizing a high-quality plasmonic nanoparticle-in-cavity(PIC)nanoantenna array,in which strong coupling between a nanoparticle(NP)dark mode with a high-order nanocavity bright mode can produce strong Fano resonance at the target wavelength.The Fano resonance can effectively boost the CFE in a PIC.A cost-effective and reliable nanofabrication method is developed using room temperature nanoimprinting lithography to manufacture high-quality PIC arrays.This technique guarantees the generation of only one gold NP at the bottom of each nanocavity,which is crucial for the generation of the expected CFE.To demonstrate the performance and application of the PIC array,the PIC array is employed as an active SERS substrate for detecting 4-aminothiophenol molecules.An experimental SERS enhancement factor of 2×10^(7) is obtained,which verifies the field enhancement and the potential of this device.Zhendong Zhu Benfeng Bai Oubo You Qunqing Li Shoushan Fan 2015Light(Science & Applications)2015,4,1:5
2A process study of electron beam nano-lithography and deep etching with an ICP system显示文摘A systemic process study on an electron beam nanolithography system operating at 100kV was pre-sent.The exposure conditions were optimized for resist ZEP520A.Grating structures with line/space of 50nm/50nm were obtained in a reasonably thick resist which is beneficial to the subsequent pattern transfer technique.The ICP etching process conditions was optimized.The role of etching parameters such as source power,gas pressure,and gas flow rate on the etching result was also discussed.A grating structure with line widths as small as 100nm,duty cycles of 0.5,depth of 900nm,and the side-wall scalloping as small as 5nm on a silicon substrate was obtained.The silicon deep etching technique for structure sizes smaller than 100nm is very important for the fabrication of nano-optical devices working in the visible regime.LI QunQing ZHANG LiHui CHEN Mo FAN ShouShan 2009Science China(Technological Sciences)2009,52,6:2
3High temperature performance of coaxial h-BN/CNT wires above 1,000 ℃:Thermionic electron emission and thermally activated conductivity显示文摘The development of wires and cables that can tolerate extremely high temperatures will be very important for probing extreme environments, such as in solar exploration, fire disasters, high-temperature materials processing, aeronautics and astronautics. In this paper, a lightweight high-temperature coaxial h-boron nitride (BN)/carbon nanotube (CNT) wire is synthesized by the chemical vapor deposition (CVD) epitaxial growth of h-BN on CNT yarn. The epitaxially grown h-BN acts as both an insulating material and a jacket that protects against oxidation. It has been shown that the thermionic electron emission (1,200 K) and thermally activated conductivity (1,000 K) are two principal mechanisms for insulation failure of h-BN at high temperatures. The thermionic emission of h-BN can provide the work function of h-BN, which ranges from 4.22 to 4.61 eV in the temperature range of 1,306-1,787 K. The change in the resistivity of h-BN with temperature follows the ohmic conduction model of an insulator, and it can provide the “electron activation energy”(the energy from the Fermi level to the conduction band of h-BN), which ranges from 2.79 to 3.08 eV, corresponding to a band gap for h-BN ranging from 5.6 to 6.2 eV. However, since the leakage current is very small, both phenomena have no obvious influence on the signal transmission at the working temperature. This lightweight coaxial h-BN/CNT wire can tolerate 1,200 ℃ in air and can transmit electrical signals as normal. It is hoped that this lightweight high-temperature wire will open up new possibilities for a wide range of applications in extreme high-temperature conditions.Xinhe Yang Peng Liu Duanliang Zhou Feng Gao Xinhe Wang Shiwei Lv Zi Yuan Xiang Jin Wei Zhao Haoming Wei Lina Zhang Jiandong Gao Qunqing Li Shoushan Fan Kaili Jiang 2019Nano Research2019,12,8:2

18Stressed carbon nanotube devices for high tunability,high quality factor, single mode GHz resonators显示文摘The emerging applications of nanoelectromechanical systems (NEMS) inground-state cooling, quantum manipulation, communication devices, etc., callfor a nanoresonator with high frequency, quality factor, and tunability, as wellas easy integration. Here we show that such a nanoresonator can be achievedby using a unique assembly technique that transfers the stressed inner shell ofcarbon nanotubes (CNTs) to a self-aligned device geometry. The as-fabricatednanoresonator shows excellent comprehensive performance, i.e., high frequency(2-3 GHz), high tunability (80-110 MHz/V), high quality factor (3×10^4), andsingle mode operation. The defect-free nature of the inner shell of the CNTgives rise to a high quality factor, and the preloaded tension improves theresonant frequency and tunability. This resonator with excellent performancealso enables the integration of homogeneous devices and will play a key role inthe emerging applications of NEMS.Xinhe Wang Dong Zhu Xinhe Yang Long Yuan Haiou Li Jiangtao Wang Mo Chen Guangwei Deng Wenjie Liang Qunqing Li Shoushan Fan Guoping Guo Kaili Jiang 2018Nano Research2018,11,11:1
