On the fundamental absorption of excitonic and non-excitonic semiconductors: an optoelectronic and thermal approach
Lizárraga Olivares, Kevin Angello (Pontificia Universidad Católica del PerúPE, 2023-08-28)In thepresent work, we study the optical properties of semiconductors near the fundamental absorption taking into account disorder induced tail states. In particular, we pay special attention to GAAs and lead halide ... -
Optical and luminiscent properties of terbium / ytterbium doped aluminum oxynitride and terbium doped aluminum nitride thin films
Tucto Salinas, Karem Yoli (Pontificia Universidad Católica del PerúPE, 2020-08-06)In the present thesis the optical and light emission properties of two systems consisting of Tb3+ and Yb3+ doped amorphous AlOxNy thin films and Tb3+ doped polycrystalline AlN thin films were analyzed. In the two ions system, ... -
Optical characterization and thermal activation of Tb doped amorphous SiC, AlN and SiN thin films
Guerra Torres, Jorge Andrés (Pontificia Universidad Católica del PerúPE, 2017-08-10)En la presente tesis se evalúan las propiedades ópticas y las características de emisión de luz de películas delgadas amorfas de AlN, SiN y SiC:H dopadas con Tb. La caracterización óptica se centra en la determinación del ...
