Two-dimensional ordered growth of InAs nanowires assisted by randomly deposited silver nanoparticles on a topographically modified surface by a focused ion beam

Autor: Mauricio P. Pires, R. Ribeiro-Andrade, Thiago L. Vasconcelos, Wagner N. Rodrigues, R. M. S. Kawabata, Patricia L. Souza

Publikováno v: Applied Surface Science. 493:271-278

Self-organized nanowires were formed on topographically and orderly modified surfaces by a focused ion beam. Silver catalyst nanoparticles were deposited on the regular shallow hole arrangements on the InP (001), which were prepared with three differ

High-quality CuInSe2 (CISe) nanowires have been prepared by a one-step evaporation process. The presented growth process results in a composite material consisting of CISe NWs on top of a polycrystalline CISe base layer. The nanowires were extensivel

Influence of surface preparation method on retained austenite quantification

Autor: L.A. Pinto, J.R.G. Carneiro, Natalia Isabel de Azevedo Lopes, D. Pérez Escobar, O.S.H. Santos, R. Ribeiro-Andrade

Publikováno v: Materials Today Communications. 24:101226

Phase identification and quantification in multiphase steels has been a major challenge due to the preparation effects and the specificities of the analysis technique. This work aimed to identify and quantify the retained austenite fraction in 15XX c

Thin film solar cells based on Cu(In,Ga)Se2 (CIGS), where just the buffer layer is changed, were fabricated and studied. The effects of two different buffer layers, CdS and ZnxSn1−xOy (ZnSnO), are compared using several characterization techniques.

Publikováno v: 2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC).

We report the growth of CuInSe 2 nanowires (NWs) using an evaporation process. The NWs grow on top of an underlying CuInSe 2 polycrystalline layer that initially forms on Si(100) substrates with native SiO 2 . Reference samples grown after removal of
