On the formalism of quantum mechanics constructed with the dispersion relation of deformed special relativity
(2011)
Over the last ten years there has been a significant effort to develop Deformed Special Relativity (DSR). This theory has two observer invariant scales: the speed of light,(c), and the Planck energy,(Ep). It is argued by ...
Síntesis y caracterización de CuIn (1-x) Ga(x) Se2 y sus propiedades fotovoltaicas
(2018-05)
In this work we have studied materials suitable to be used as an absorbing layer in thin-film solar cells. Photovoltaic materials based in CuIn (1-x) Ga(x) Se2 (CIGS) are now conventionally used the solar panel industry. ...
Electron transport through graphene structures
(2012)
Intrinsic graphene is the first atomic monolayer structure produced experimentally. Its unique two dimensional geometric structure along with its electronic structure (Dirac cone) make it an ideal system for the fundamental ...
Chalcogenide based (CuInS2/ZnS, CuInSe2/ZnSe) core/shell quantum dots for photodynamic therapy
(2015)
Strong luminescent CuInX2/ZnX (X=S,Se) core/shell quantum dots were synthesized by a novel nontoxic and inexpensive organometallic method in two simple steps of CuInS2 and CuInSe2 core formation and ZnS and ZnSe shell over ...
Effects of degraded tract inner barrel in the CMS tracking reconstruction
(2011)
This thesis reports the impact of the first two Tracker Inner Barrel’s layers degradation on the CMS detector tracking efficiency and how the new tracking detector and geometry proposed for the Phase 1 upgrade will improve ...
Estudio comparativo de películas de aln crecidas por erosión iónica dc pulsada
(2010)
The purpose of this work focused on evaluating the structure and composition of AlN thin films deposited on Si (100), Si (111), sapphire and glass substrates. For this purpose, AlN thin films were deposited by the technique ...
Estudio de generación de energía con celdas de combustible con membrana poly diallydimethylammonium chloride (pdadmac) como polímero de intercambio protónico
(2010)
Fuel cells were built with poly diallydimethylammonium chloride or PDADMAC (by its initials in English) as proton exchange membrane and were compared with earlier studies of fuel cells constructed by other methods and / ...
Estudio de dicroismo circular magnetico en el sistema ZnO1−xCoxO
(2011)
We studied the magnetic circular dichroism spectra (MCD) of ZnO1−xCoxO (x = 0.00, x = 0.05 and x = 0.01) thin films. No magneto-optical effect was observed in the ZnO sample, while samples of ZnO:Co 5% and ZnO:Co 10% MCD ...
Analysis of a Λ_(b)^(0) decay
(2013)
This thesis presents a preliminary results for the first observation of the exclusive Λ_(b)^(0) → Λ0ψ(2S) decay with a significance of 7.8 σ. The data sample used in this work, corresponding to an integrated luminosity of ...
Tuning of structural and magnetic properties of La1−xSxMnO3
(2018)
This thesis investigated the effect of incorporation of Sr2+ and Ca2+ ions on the structural and magnetic properties of LaMnO3 (LMO) powders synthesized by sol-gel and thermal treatment method at 900°C. X-ray diffraction ...
