Hydrogen sensor using optical reflectance from porous silicon with a palladium thin film
Lowrie, Christopher G.; Earles, S. K.; Pozo de Fernandez, Maria E. (2008-02-13)Results of a hydrogen sensor based on light scattering from a porous silicon surface coated with a thin palladium film are discussed. Reflected light scattered from the rough surface of porous silicon surface with a thin ... -
Porous silicon surface feature size estimation using the reflectance spectrum
Lowrie, Christopher G.; Earles, S. K.; Pozo de Fernandez, Maria E. (2008-02-13)In this paper we excite the surface of porous silicon with incoherent, broad band white light and observe the spectrum of colors reflected from the surface. Using an atomic force microscope images from red and green porous ...
