In this paper, we present results obtained by an optical technique, namely, reflectance anisotropy spectroscopy (RAS), applied to a series of GaAs1−xBix samples grown molecular beam epitaxy (MBE) under different strain conditions with the increasing concentration Bi, up higher value about 7%. The epitaxial buffer layers for growing layer were prepared either compressive (as it is commonly done)...

The objective of this work was to compare the accuracy of analyte concentration estimation when using transmission versus diffuse reflectance spectroscopy of a scattering medium. Monte Carlo ray tracing of light through the medium was used in conjunction with pure component absorption spectra and Beer-Lambert absorption along each ray's pathlength to generate matched sets of pseudoabsorbance sp...
