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 ...
A turning bands method for simulating isotropic Gaussian random fields on the sphere
(Elsevier B.V., 2019)
We introduce a novel approach to simulate Gaussian random fields defined over spheres of ℝ3. Through continuation we embed the process on the sphere in a nonstationary random field of ℝ3 to use a turning bands method. We ...
Flat bands and PT symmetry in quasi-one-dimensional lattices
(American Physical Society, 2015)
We examine the effect of adding PT-symmetric gain and loss terms to quasi-one-dimensional lattices (ribbons) that possess flat bands. We focus on three representative cases: the Lieb ribbon, the kagome ribbon, and the stub ...
Performance of pre-production band 1 receiver for the Atacama Large Millimeter/submillimeter Array (ALMA)
(SPIE, 2018)
The Atacama Large Millimeter/submillimeter Array (ALMA) Band 1 receiver covers the frequency range of 35-50 GHz. An extension of up to 52 GHz is on a best-effort basis. A total of 73 units have to be built in two phases: ...
Photonic flat band dynamics
(Taylor & Francis, 2021)
During the last decades, researchers of different scientific areas have investigated several systems and materials to suggest new ways of transporting and localizing light. These problems are probably main goals in any ...
1π → 1π* ultraviolet absorption bands and electronic charge transfers in singlet excited states of sulfur aromatic heterocycles
(2005)
Indoline-2-thione (BC), benzimidazole-2-thione (BN), benzoxazole-2-thione (BO), and benzothiazole-2-thione (BS) define an interesting series of aromatic compounds containing a NCS synthonic unit in a heterocyclic ring of ...
Comparing sequential Gaussian and turning bands algorithms for cosimulating grades in multi-element deposits
(Elsevier, 2015)
Stochastic simulation is increasingly used to map the spatial variability in the grades of elements of interest and to assess the uncertainty in the mineral resources and ore reserves. The practical implementation requires ...
Pre-stimulus EEG oscillations correlate with perceptual alternation of speech forms
(Elsevier, 2016)
Speech perception is often seen as a passive process guided by physical stimulus properties. However, ongoing brain dynamics could influence the subsequent perceptual organization of the speech, to an as yet unknown extent. ...
Similarities and differences among the chromosomes of the wild guinea pig Cavia tschudii and the domestic guinea pig Cavia porcellus (Rodentia, Caviidae)
(Pensoft Publ, 2014)
Cavia tschudii Fitzinger, 1867 is a wild guinea pig species living in South America that according to the analysis of mitochondrial genes is the closest wild form of the domestic guinea pig. To investigate the genetic ...
