  • Synthesis of Tetrapodlike Zinc Oxide Nanostructures by Inductive Heating
    IEEE Electron Device Letters, 2009
    Co-Authors: Yongming Tang, Ke Qu, Xiaxi Yang, Peng Zhang, Baoing Wang
    Abstract:

    The Inductive Heating method is used to synthesize regular tetrapodlike zinc oxide nanostructures on a glass substrate. The morphology of tetrapodlike ZnO nanostructures is investigated by scanning electron microscopy. It is found that the tetrapodlike ZnO structure fabricated by Inductive Heating is smaller than that fabricated by PVD. Therefore, more emission sites can be generated with the tetrapodlike ZnO structures obtained by Inductive Heating. The field-emission characteristics of ZnO nanostructures are also measured in this letter. The measurement results show that the tetrapodlike ZnO nanostructures obtained by the Inductive Heating method have low turn-on electric field and high emission current. Its field-emission performance is better than that of the tetrapod ZnO emitters obtained by PVD due to its good morphology and adhesion on substrate. Because ZnO nanostructures can grow directly on a glass substrate with the Inductive Heating method, it is very useful for the application in the field-emission display panel.

  • Synthesis and field emission property of tetrapod-like zinc oxide nanostructures by Inductive Heating
    2009 IEEE International Vacuum Electronics Conference, 2009
    Co-Authors: Peng Zhang, Wei Lei, Xiaxi Yang
    Abstract:

    Inductive Heating method was used to synthesis regular tetrapod-like zinc oxide within 1 minute in the air. The synthesis of the nanostructure was interpreted by the Vapor-Solid (VS) growth mechanism. The nanostructure was verified to be pure ZnO nanostructure by X-ray diffraction (XRD) spectrum. Field emission measurement was applied to prove that it owns low turn-on field and large emission current. Tetrapod-like ZnO nanostructures synthesized in our method are technologically useful for vacuum electron devices because they could be synthesized sufficiently and rapidly in a room temperature.

  • Room temperature fast synthesis of zinc oxide nanowires by Inductive Heating
    Applied Physics Letters, 2007
    Co-Authors: Lei Luo, Brian D. Sosnowchik, Liwei Lin
    Abstract:

    ZnO nanowires have been rapidly synthesized using Inductive Heating in a room temperature environment. Nanowires with random and aligned orientations were grown on silicon and 4H-SiC (0001) substrates in less than 5min, respectively, using ZnO/graphite as the solid source powder. Scanning electron microscopy showed nanowire diameters of 20–120nm and lengths up to 5μm, and transmission electron microscopy verified the single-crystalline lattice of the nanowires. Electrical properties were studied by connecting a single ZnO nanowire in the field-effect transistor configuration. This demonstration further illustrates the feasibility of a simple and fast nanoscale synthesis using Inductive Heating for nanomaterial synthesis.ZnO nanowires have been rapidly synthesized using Inductive Heating in a room temperature environment.

  • Rapid synthesis of carbon nanotubes by bulk and localized Inductive Heating
    2007 IEEE 20th International Conference on Micro Electro Mechanical Systems (MEMS), 2007
    Co-Authors: Brian D. Sosnowchik, Liwei Lin
    Abstract:

    In this work, we report a rapid yet simple methodology for the synthesis of carbon nanotubes (CNTs) in a room temperature environment using an Inductive Heating system with either a) bulk synthesis on silicon chips, or b) local synthesis on suspended MEMS structures. This setup enables growth and integration of CNTs with MEMS structures in a matter of 1-2 minutes. For bulk synthesis, high growth rates of up to 200 mum/min were obtained, resulting in growth of vertically aligned CNTs with an average diameter of 6.8nm. Integration from bulk- grown CNTs on MEMS structures resulted in lower resistances from larger diameter CNTs. Localized synthesis and integration was also obtained on suspended copper microstructures, illustrating an ohmic CNT response with a resistance of 110 kOmega. The breadth of synthesis and integration capabilities enabled by Inductive Heating illustrates a new class of rapid synthesis for vapor-liquid-solid-grown nanostructures.

  • Rapid synthesis of carbon nanotubes via Inductive Heating
    Applied Physics Letters, 2006
    Co-Authors: Brian D. Sosnowchik, Liwei Lin
    Abstract:

    A rapid yet simple methodology to synthesize carbon nanotubes (CNTs) in a room temperature environment has been demonstrated using an Inductive Heating system. Substrates of either heavily doped silicon or nickel-coated, lightly doped silicon have been used to synthesize CNTs using Fe as the catalyst. Aligned carbon nanotubes with growth rates as high as 200μm∕min have been achieved in less than 1min. Transmission electron micrographs illustrated average diameters of 8 and 6.8nm for CNTs grown under average temperatures of 760 and 910°C, respectively. This system allows the synthesis of CNTs that is easy to set up, fast, clean, and inexpensive.

  • Rapid Silicon-to-Steel Bonding via Inductive Heating
    Microelectromechanical Systems, 2006
    Co-Authors: Brian D. Sosnowchik, Liwei Lin, Albert P. Pisano
    Abstract:

    In this work, we present a rapid, low temperature process for the bonding of silicon to steel through the use of Inductive Heating for MEMS sensor applications. The bonding process takes as short as three seconds with a maximum bonding temperature as low as 230°C at the steel surface. The bonding strength is strong, and causes minimal damage to steel. The process has also been shown to work using leaded and leadfree bonding solder with minimal surface preparation to the steel. Four characterization experiments – tensile and compressive 4-point bend, axial extension, and fatigue tests – have been performed to validate the bonding process and materials. As such, this work illustrates the promise of applying Inductive Heating for the rapid silicon bonding to steel components for MEMS sensing applications.Copyright © 2006 by ASME
