Influence of Pb2+ doping in the optical and electro-optical properties of SnO2 thin films
(2022-02-15)
Different types of doping incorporated to tin dioxide (SnO2) have been reported in order to control its bandgap aiming optoelectronic applications, such as transparent electrodes, solar cells and displays. In this work, ...
Urbach energy parameter of flash evaporated amorphous gallium arsenide films
(2002-04-01)
The dependence of the optical absorption edge on the deposition crucible temperature is used to investigate the electronic states in As-rich a-GaAs flash evaporated films. The Urbach energy parameter, determined from ...
Structural and optical properties o plasma-deposited a-C:H:Si:O:N films
(2021-01-01)
Thin a-C:H:Si:O:N films were deposited from plasmas fed hexamethyldisiloxane, oxygen and nitrogen, and characterized as a function of the partial pressure of oxygen in the feed, Rox. Deposition rates varied from 10 to 27 ...
