Bandgap engineering in aperiodic Thue-Morse graphene superlattices
(American Institute of Physics, 2019-01-25)
The lack of bandgap in graphene is the main factor that prevents that this outstanding material be implemented in optoelectronics. In this work, we show that by nanostructuring graphene aperiodically it is possible to have ...
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, ...
Near-IR bandgap engineering employing the alloy (CdTe)1-x(In2Te3)x

Plasmon-enhanced optical absorption with graded bandgap in diamond-like carbon (DLC) films
(Springer, 2017)
Diamond-like carbon (DLC) films with tunable optical bandgap (Eg) were successfully deposited on glass and n-Si (100) substrates by radio frequency (RF)-sputtering technique in different argon (Ar) and acetylene (C2H2) ...

Enhanced photoabsorption properties of composites of Ti/TiO2 nanotubes decorated by Sb2S3 and improvement of degradation of hair dye
(Elsevier B.V., 2014-02-15)
The present work illustrates the great potentiality of Ti/TiO2/Sb2S3 composite electrode prepared by electrochemical anodization of Ti foil in aqueous electrolyte (1 mol L-1 NaH2PO4 + 0.3 wt.% HF followed by chemical bath ...
Enhanced photoelectrocatalytic degradation of an acid dye with boron-doped TiO2 nanotube anodes
(Elsevier B.V., 2015-02-01)
The present work evaluates the performance of boron-doped TiO2 nanotubes (B-TiO2 NTs) prepared by electrochemical anodization in the presence of 70, 140, 280 and 560 ppm of boron when activated by UV/visible irradiation. ...
Photonic Bandgap Inspection in 2-D Sublattices
