Effect of the crystal size on the X-ray diffraction patterns of isolated orthorhombic starches: A-type
Mario E. Rodriguez-Garcia, Sandra M. Londoño-Restrepo, Cristian F. Ramirez-Gutierrez +1
The x-ray diffraction (XRD) patterns reported for starch in the literature describes it as a semicrystalline polymer that indicates that amorphous and crystalline regions form it,…
Porosity and roughness determination of porous silicon thin films by genetic algorithms
C. F. Ramirez-Gutierrez, J. D. Castaño-Yepes, M. E. Rodriguez-Garcia
The problem of determining the porous silicon (PSi) optical constants, thickness, porosity, and surface quality using just reflectance data is board employing evolutionary algorith…
Modeling the photoacoustic signal during the porous silicon formation
J. D. Castano-Yepes, C. F. Ramirez-Gutierrez, M. E. Rodriguez-García
Within this work, the kinetics of the growing stage of porous silicon (PS) during the etching process was studied using the photoacoustic technique. A p-type Si with low resistivit…
In situ photoacoustic characterization for porous silicon growing: detection principles
C. F. Ramirez-Gutierrez, Jorge David Castano-Yepes, M. E. Rodriguez-Garcia
There are a few methodologies to monitoring the Porous Silicon (PS) formation in-situ. One of these methodologies is photoacoustic. Previous works that reported the use of photoaco…
