On the fundamental absorpion of amorphous semiconductors
(Pontificia Universidad Católica del Perú, 2016-06-20)
The present thesis reviews different models that describe the fundamental absorption of
amorphous semiconductors. These models make use of the electronic density of states to
shape the absorption coefficient in the ...
Structural, luminescence and Judd-Ofelt analysis to study the influence of post-annealing treatment on the AIN:Tb thin films prepared by radiofrequency magnetron sputtering
(Pontificia Universidad Católica del Perú, 2016-06-20)
This thesis investigates the effects of the annealing treatments on the spontaneous emission,
radiative lifetime, composition and structure of terbium doped aluminum nitride films
deposited on silicon substrates by radio ...
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, ...
