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 ...
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 ...
Gamma band activity in the reticular activating system
(Frontiers Head Office-Online publication, 2012-01)
This review considers recent evidence showing that cells in three regions of the reticular activating system (RAS) exhibit gamma band activity, and describes the mechanisms behind such manifestation. Specifically, we discuss ...
Microcalcification enhancement and classification on mammograms using the wavelet transform
(2008-11-24)
This paper presents a method to enhance microcalcifications and classify their borders by applying the wavelet transform. Decomposing an image and removing its low frequency sub-band the microcalcifications are enhanced. ...
SPIN-ORBIT EFFECTS ON HEAVY-METAL OCTAHEDRAL CLUSTERS
(ELSEVIER SCIENCE BV, 1993)
The relativistic electronic structure of octahedral Mo6, W6, Ag6 and Au6 clusters has been investigated using the self-consistent field Dirac scattered wave (SCF-DSW) method. It is shown that spin-orbit interaction breaks ...
