Optical and luminiscent properties of terbium / ytterbium doped aluminum oxynitride and terbium doped aluminum nitride thin films
(Pontificia Universidad Católica del Perú, 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, ...
On the fundamental absorption of excitonic and non-excitonic semiconductors: an optoelectronic and thermal approach
(Pontificia Universidad Católica del Perú, 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 ...
