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, ...
Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...

Spectroscopy studies of 4H-SiC
(2003)
Calculations of the total dielectric functions and the optical bandgap energy (OBGE) of 4HSiC were performed by the full-potential linear muffin-tin-orbital method. The results are compared to spectroscopic ellipsometry ...
Structure, electronic structure, optical and magnetic studies of double perovskite Gd2MnFeO6 nanoparticles: First principle and experimental studies
(Elsevier, 2020)
Multifunctional materials are greatly appealed in electrical, electronic and magnetic devices which are developed by several researchers for future device fabrications. Among such materials, the double perovskites with ...
Design of diblock co-oligomers as low bandgap small molecules for organic solar cells
(2017-12-12)
The properties of a particular kind of small molecule that is built from two oligomers of different monomers, i.e. a diblock co-oligomer, as the electron donor in the active layer of organic solar cells are investigated ...
