Synthesis and characterization of self-assembled, high aspect ratio nm-scale columnar silicon structures
(Institute of Electrical and Electronics Engineers Inc., 2013-06)
The aim of this work is to synthesize nm-scale columnar structures in Si principally for solar cell applications. These structures are also desirable as templates for heteroepitaxial growth of SixGe1-x. A nanostructured ...
Role of micro and nanostructures in enhancing near IR optical absorption in Silicon
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
Role of micro and nanostructures in enhancing IR transmission in Si wafers has been investigated. Based on feature dimensions, incident light interaction can be described in terms of: (a) geometrical optics for wavelengths ...
Optical characterization of SixGe1-x films grown on nanostructured Si substrates
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
High quality Ge and SixGe1-x films grown on Si substrates are attractive for a wide range of applications in optics, optoelectronics, and high efficiency solar cells. In this study, heteroepitaxial growth of Ge on ...
