Sn-doped CdTe as promising intermediate-band photovoltaic material
(Institute of Physics, 2017)
The formation energies, charge transition levels and quasiparticle defect states of several tin-related impurities are investigated within the DFT + GW formalism. The optical spectrum obtained from the solution of the ...
Study of the catalytical intermediates of metalloporphyrins supported on imidazole propyl gel
(Elsevier B.V., 1997-03-14)
In this work, the catalytic intermediates for Fe(TPP)(+), Fe(TDCPP)(+), Fe(TFPP)(+), Mn(TPP)(+) and Mn(TDCPP)(+) supported on imidazole propyl gel with PhIO were studied by UV-Vis spectrophotometry. For Fe(TPP)+ and Fe(TFPP)+ ...

Bismuth Doping of CdTe: The Effect of Spin–Orbit Coupling
(Wiley-VCH Verlag GmbH, 2020)
Using the Heyd, Scuseria, and Ernzerhof (HSE) hybrid functional, with the range-separation parameter modified to match the CdTe bandgap, the electronic structure and thermodynamic properties of bismuth-doped CdTe are ...
First principle study of V-implantation in highly-doped silicon materials
(Elsevier, 2017)
Density Functional Theory (DFT) has been used to study structural and electronic properties of new compounds based on V-implanted Si and their potential as infrared photodetectors. Effects derived from the implantation of ...
Multi-shell spherical GaAs/AlxGa(1-x)As quantum dot shells-size distribution as a mechanism to generate intermediate band energy levels
(Elsevier, 2017-04)
In this work the generation of an intermediate band of energy levels from multi-shell spherical GaAs/AlxGa(1-x)As quantum dot shells-size distribution is reported. Within the effective mass approximation the electronic ...
Comparative cytogenetic studies of Bufo ictericus, B. paracnemis (Amphibia, Anura) and an intermediate form in sympatry
(Sociedade Brasileira de Genética, 2003-01-01)
Specimens of Bufo ictericus, Bufo paracnemis and a third type, considered an intermediate subgroup between these species, were cytogenetically studied by conventional Giemsa staining, C-banding and staining of the nucleolus ...
