  We report Raman scattering and field emission properties of rutile RuO2 nanorods obtained by metalorganic chemical vapor deposition. The RuO2 nanorods have lengths up to several micrometers and diameters in the range of 10–50 nm. The nanosize dependencies of the peak shift and the broadening of the three first-order Raman modes agree well with those calculated on the basis of the phonon confinement

  我们报告了通过金属有机化学气相沉积获得的金红石 RuO2 纳米棒的拉曼散射和场发射特性。RuO2 纳米棒的长度可达几微米，直径范围为 10-50 nm。三个一阶拉曼模式的峰位移和展宽的纳米尺寸依赖性与基于声子限制模型计算的那些非常吻合。RuO2纳米棒独特的几何特征对场增强（β~1153）有很强的影响，这导致在发射开始时定义的低阈值场（Eth~4.9V∕μm）。驱动10μA∕cm2电流的低导通场约为10.3V∕μm，与非晶碳膜相当。我们的结果表明，RuO2 纳米棒由于几个优点为场发射器提供了极好的替代品，

  metalorganic chemical vapor deposition. The geometry of these nanorods resembles an obelisk with an off-center tip. The aspect ratios of nanorod tips are between 0.55 and 0.73. The field emission properties of the RuO2 nanorods are studied and the stability of its emission current is assessed. The field emission results demonstrate that RuO2 nanorods material is an emitter of potential.

  Raman scattering (RS) and field emission scanning electron microscopy (FESEM) have been used to extract microstructural information of RuO2 nanorods (NRs) and a two-phase system comprising NRs embedded in polycrystalline matrix deposited on different substrates by the metal-organic chemical vapor deposition method. The red shifts and asymmetric broadening of the Raman line shape for the NRs are analyzed by the spatial correlation model. The deduced spatial correlation length 1 is found to be much smaller than that of the average size L-0 estimated from the FESEM images. The Raman features for the two-phase system can be resolved into two parts: a Lorentzian line shape feature corresponding to the polycrystallite at higher frequency side and an asymmetrically broadened NRs' signature located at lower frequency end. The volume fraction of NRs in the two-phase system can be determined from the analysis. These results demonstrate the significance of RS as a structural characterization method when used in conjunction with FESEM. (C) 2004 Elsevier Ltd. All rights reserved.
