effective surface passivation of crystalline silicon by rf sputtered Aluminum Oxide
Physica Status Solidi-rapid Research Letters, 2009Co-Authors: Tsutsung Li, Andres CuevasAbstract:In recent years, excellent surface passivation has been achieved on both p-type and n-type surfaces of silicon wafers and solar cells using Aluminum Oxide deposited by plasma-assisted atomic layer deposition. However, alternative deposition methods may offer practical advantages for large-scale manufacturing of solar cells. In this letter we show that radio-frequency magnetron sputtering is capable of depositing negatively-charged Aluminum Oxide and achieving good surface passivation both on p-type and n-type silicon wafers. We thus establish that sputtered Aluminum Oxide is a very promising method for the surface passivation of high efficiency solar cells. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Ultrafine Aluminum Oxide production by detonation
Explosion and Shock Waves, 2005Co-Authors: Xie Xing-huaAbstract:The experimental study of ultrafine Aluminum Oxide formed by the mixture detonation of Aluminum nitrate and PETN used to maintain steady detonation is presented. The detonation product without any disposal is analysed by TEM、XRD、DTA/TGA and BET. The results show that the detonation product is ultrafine and globose Aluminum Oxide, the range of granularity is from 10~50 nm, the average size is 25 nm. The Aluminum Oxide is γ Aluminum Oxide. Based on the experimental results, we concluded that the ultrafine Aluminum Oxide directly agglomerated each other with the ion or molecule formed in the reaction area of detonation. Because the process of agglomeration and growth completed in the microsecond range, the grains did not grow towards the favored direction and took spherial form.

Homogeneous deposition of nickel in pores of the ordered thin Aluminum Oxide
Russian Microelectronics, 2013Co-Authors: A. I. Vorob’eva, E. A. Utkina, O. M. KomarAbstract:Fabrication of a matrix of ordered vertically oriented nickel nanocolumns with the use of a porous Aluminum Oxide template is considered. The effect of thinning of a barrier layer at the bottom of the Aluminum Oxide pores on the nucleation and growth of ordered metal nanocolumns is discussed. Morphological parameters of Ni nanocolumns fabricated in different regimes are studied by atomic force microscopy. Kinetic regulations and conditions of the electrochemical deposition of nickel into a porous Aluminum Oxide template are investigated.

Aligned carbon tubes synthesized using porous Aluminum Oxide
Russian Microelectronics, 2012Co-Authors: A. I. Vorob’eva, B. G. ShulitskiiAbstract:The fabrication of a matrix of highly ordered vertically aligned carbon tubes synthesized using a porous anodic Aluminum Oxide template is considered. The effect of synthesis regimes on the order and topological characteristics of carbon tubes is investigated. The effect of structural and morphological changes in the porous Aluminum Oxide which take place during the high-temperature synthesis of carbon tubes on the origin and growth of the latter is discussed.

Nanocomposite carbon material with ordered structure synthesized using porous Aluminum Oxide
Nanotechnologies in Russia, 2011Co-Authors: A. S. Basaev, B. G. Shulitskii, E. L. Prudnikova, A. M. Mozalev, Yu. P. Shaman, Vladimir Labunov, A. I. Vorob’eva, V. N. KukinAbstract:The synthesis of nanocomposite carbon material with an ordered structure in a porous anodic Aluminum Oxide template is considered. A template with a highly ordered structure provides the formation of an array of aligned carbon tubes with high aspect ratios (higher than 1000) in polycrystalline anodic Aluminum Oxide. The obtained material is studied using scanning and transmission electron microscopy, Raman scattering spectroscopy, Auger electron spectroscopy, and infrared and X-ray photoelectron spectroscopy.
