在真空状态下,在两个石英坩埚分别装入纯In,In、Sn(Wt=10%)合金,并按所沉积膜的种类(In2O3或ITO)将某一石英坩埚装入加热器,当真空度达到要求后,通入氧气并开启加热器,可在玻璃基板上制备In2O3或ITO薄膜。制备的ITO薄膜的方块电阻为10Ω/□,可见光平均透过率≥90%,制备的In2O3薄膜的方块电阻为35Ω/□,可见光平均透过率≥90%。是太阳能光伏产品及显示器件导电膜的理想选择。 相似文献

柔性衬底ITO薄膜的制备及其光电性能研究 总被引:5,自引:3,他引:2
在室温下,采用直流反应磁控溅射法,在聚酯薄膜(PEP)衬底上镀制了高性能的ITO薄膜。为了提高薄膜与基底的结合力,溅射前采用多弧离子源对PEP表面进行了等离子体清洗。研究了溅射工艺参数对ITO薄膜的光电性能和红外发射率的影响规律,探讨了ITO膜的透光和导电机理,并分析了方块电阻与红外发射率的相互关系。实验结果表明,通过等离子体清洗,ITO薄膜的结合力和光电性能都得到了改善。ITO薄膜的红外发射率和方块电阻受制备条件的影响规律具有相似之处,红外发射率随薄膜方块电阻的增大而呈增加的趋势。 相似文献

ITO用作铁电薄膜电极的研究 总被引:4,自引:0,他引:4
研究了sol-gel掺锡氧化铟(ITO溶胶在SiO2/Si衬底和光学玻璃衬底上的成膜及结晶性能,并与CVD法生长的ITO薄膜作了对比。结论是:sol-gelITO膜,虽然具有与CVD ITO膜相似的结晶性能和较高的导电性,但以sol-gel ITO膜作下电极,无法使PLT、PZT的sol-gel膜具有明显的结晶取向。因漏电太大,sol-gel ITO也无法作sol-gel铁电膜(如PLT,PZT)的上电极。但在CVD ITO膜上,sol-gel铁电膜能很好结晶,且Au/PLT/ITO电容,具有良好的电学性能。 相似文献

Multifunctional single crystalline tin-doped indium oxide (ITO) nanowires with tuned Sn doping levels are synthesized via a vapor transport method. The Sn concentration in the nanowires can reach 6.4 at.% at a synthesis temperature of 840?°C, significantly exceeding the Sn solubility in ITO bulks grown at comparable temperatures, which we attribute to the unique feature of the vapor-liquid-solid growth. As a promising transparent conducting oxide nanomaterial, layers of these ITO nanowires exhibit a sheet resistance as low as 6.4 Ω/[Symbol: see text] and measurements on individual nanowires give a resistivity of 2.4 × 10(-4) Ω cm with an electron density up to 2.6 × 10(20) cm(-3), while the optical transmittance in the visible regime can reach ~ 80%. Under the ultraviolet excitation the ITO nanowire samples emit blue light, which can be ascribed to transitions related to defect levels. Furthermore, a room temperature ultraviolet light emission is observed in these ITO nanowires for the first time, and the exciton-related radiative process is identified by using temperature-dependent photoluminescence measurements. 相似文献

This study has investigated the influence of the radio frequency (rf) power and working pressure on the properties of indium tin oxide (ITO) thin films, which were prepared by long-throw rf magnetron sputtering technique at room temperature. For 200 nm thick ITO films grown at room temperature in pure argon pressure of 0.27 Pa and sputtering power of 40 W, sheet resistance was 26.6 ?/sq. and transmittance was higher than 88% (at wavelength 500 nm).

在室温条件下通过直流磁控溅射法在普通玻璃基体上制备了光电性能优良的ITO薄膜。靶材为ITO陶瓷靶,其中In2O3与SnO2的质量比为9∶1。运用UV-2550紫外可见光光度计测量样品的透光率,采用SZT-2四探针测试仪测量样品表面的电阻率,用扫描电镜(SEM)对样品进行表征。研究了溅射压强、溅射功率等参数对薄膜光电性能的影响。研究表明,ITO薄膜的电阻率随着溅射功率的增大而减小,在溅射功率为110W时ITO薄膜的透光率有相对好的数值。溅射压强为1.0Pa时既能保持ITO薄膜低的电阻率又能保证高的透光率。 相似文献

Nanocrystalline ITO-Ag powders were prepared using a coprecipitation method. Surface modified silver nanoparticles were mixed with the indium tin hydroxide precursor before the sintering process. The ITO-Ag nanocomposite powder was formed into pellets by uniaxial pressing process. The effect of addition of silver to the electrical and structural properties of ITO powder compact was studied. The relative density of the metal filled composite ITO-Ag powder compact is higher than the pure ITO powder compact. The result may be attributed to the melted silver eventually fills the void space between agglomerate pores and hence enhances the interconnection between nanocrystalline ITO powders. The crystal phase and particle size of ITO powder and ITO-Ag powder were measured by powder X-ray diffraction and the surface morphology of powder compact was investigated using a scanning electron microscope. 相似文献

Tin-doped indium oxide (ITO) ceramic targets with three types of grain size (<10, 10–20 and >20 μm) were prepared by controlling sintering process. It is found that all targets show polycrystalline structure and a rapid heating and short holding time contributes to refining grain size. The ITO films were deposited using these ITO targets with three types of grain sizes under dc and rf mode. The effects of grain size on the structural, electrical and optical properties of the as-deposited films were systematically investigated. The results indicate that all ITO films are the (222) preferred orientation, and the surface grain morphologies are round (dc mode) and triangular (rf mode). The sheet resistance, transmittance and uniformity of the ITO films are significantly impacted by the grain size. The small grain size (<10 μm) contributes to improving the uniformity of electrical and optical properties. The optimal uniformity of sheet resistance under dc and rf mode is about 13 and 10 %, respectively. 相似文献

利用射频磁控溅射在玻璃衬底上制备了氧化铟锡(ITO)薄膜,分别采用两种方法对薄膜进行氮化处理,即:(1)利用氩气溅射在室温下制备薄膜,随后在氮气和氨气气氛下对薄膜进行热处理;(2)利用氩气/氮气共溅射成膜.利用X射线衍射、霍尔效应、UV-vis-NIR分光光度计等测试手段对薄膜样品进行表征,对比研究了两种氮化处理方法对ITO薄膜光电特性的影响.结果发现对于低温生长的薄膜,两种方法均能明显提高其在可见光区的透过率.氩气/氮气共溅射的方法会降低薄膜的结晶程度,降低载流子浓度,但使得其紫外/可见/近红外光谱发生明显红移;而热处理方法则能增加薄膜的结晶程度,提高其导电能力. 相似文献
