We present a reliable and cost effective 2-step metal-assisted-etching (MAE) texturing technique that forms random-micropores. The optical behavior of the random-micropores is systematically studied. We demonstrate that the random-micropore morphology is capable of suppressing front surface reflection more efficiently than not only the conventional acidic texturing but also the widely used random...
In this study, ZnO nanowires (NWs) were synthesized by hydrothermal growth process under the assistant of external electric field. Hydrothermal method is a low temperature and low-cost process for fabrication of single crystalline nanostructures. The ZnO film on Si substrate was deposited first by RF-sputter as a seed layer. Zn(NO3)·6H2O and (CH2)6N4 were then used as reactants in the hydrothermal...
SiGe nanostructures with different kinds of configurations have been successfully synthesized on glass substrate by chemical vapor deposition. The formation of different SiGe nanostructure can be easily tuned by controlling the growth conditions. The morphologies and compositions of the nanostructures were characterized by SEM and Raman spectroscopy. The present method provides an easy way for flexible...
In this work, the effect of substrate position on the formation of ZnO nanostructures synthesized by thermal evaporation of zinc oxide (ZnO) and carbon nanotubes (CNTs) on silicon substrate is investigated. The multi-wall CNT powder made by chemical vapor deposition was mixed with ZnO powder with a molar ratio of 1:1. The source material was put into the middle of chamber while Si substrates were...
