| | The present paper is about the thin film SnO_2 which is manufuctured by evaporation method. The thickness of the sample is 5000(?), the carrier concentration measured by Hall effect is 4.99×10~(20) cm~(-3), the Hall mobility is 4.26 cm~2 V~(-1)S~(-1), the conductivety is 340.6 Ω~(-1)cm~(-1), the conductivity pattern is of n-type and the light transmissivity T (λ=0.589μm) is 85%. The carrier concentration is determined as the main factor for controlling conductivety properties. This film can be used as the t... | | 本文对用气态蒸发法制备的S_nO_2薄膜进行了基本物理特性的研究。试样薄膜的厚度为5000,利用霍耳效应测定其载流子浓度为4.99×10~(20)cm~(-3),霍耳迁移率为4.26cm~2V~(-1)S~(-1),导电类型为n型,用二探针法测定其电阻率为2.9×10~(-3)Ω·cm.光学测定其透过率T(λ=0.589μm)可达85%以上。由基本特性判定出支配S_nO_2薄膜电导特性的主要因素是载流子浓度,同时说明它可以用作电视技术中的透明电极材料,也可与其它半导体材料形成异质结制作太阳能电池。 | | 文摘来源 | | The conditions of generated polyaniline film on platinum,glass car-bon and epitaxial silicon electrodes by using electrochemical polymericmethod and the relationship between electroactive and electrochromaticproperties for this film are discussed.Aniline film adherence at n~+/p-Siphotoanodes with Pt spettering layer is better than that at bare n~+/p-Si.It enhances the stability of photoanodes. | | 讨论了用电化学聚合法在铂、玻碳以及在p 型和n 型外延硅电极上生成聚苯胺膜的条件、膜的电活性与其变色性之间的关系。在有铂溅射薄层的n~+/p—Si光阳极上、膜的附着性较牢固、它使光阳极的稳定性得到改进。 | | 文摘来源 | | This paper studies the properties of the mechanical deformation of N-type and P-type monocrystal silicon under external load. Moiré interferometry and speckle method are used to measure the deformation, and the results show that deformation decreases with the increase of load. This implies that there are lowenergy vacant layers in monocrystal silicon. The density of the silicon can be increased by compacting the vacant layers under external load. | | 本文的目的在于研究n型和p型硅单晶材料在外荷载作用下的变形性质。将云纹干涉和散斑干涉技术用于硅单晶材料变形性质的测定。试验结果表明,当载荷值小时,其变形量增大,而当载荷增加时,其变形增长量减小,这一现象证实了在硅晶体中存在着弱结合空位层,在外载荷作用下,排出晶体中的空位,致使晶体增密,或者说提高了硅单晶的密度所致。 | | 文摘来源 | |   | | << 更多相关文摘 |
