Advanced semiconductors for photo-electrocatalytic solar fuel production
Universitat Jaume I (2020-07-20)Uno de los retos actuales de la ciencia y la tecnología es el desarrollo y utilización de fuentes de energías limpias, sostenibles y seguras, con el fin de sustituir el uso de combustibles fósiles. La energía solar, única ... -
Advanced Studies on Dye-Sensitized Solar Cells
Universitat Jaume I (2013-05-13)The conversion of sunlight into electricity is one of the most promising energy sources because is renewable and available worldwide. Therefore, is desirable to develop low cost, stable and efficient photovoltaic devices ... -
Correlation in narrow nanorods: a variational potential–configuration interaction scheme
Institute of Physics (2009)Abstract. Full configuration interaction calculations of two electrons in narrow semiconductor nanorods are carried out employing different orbital basis sets. It is shown that the usual configurations built from ... -
Doping and phase transitions processes on semiconductors and vibrational properties in complex glasses: A theoretical and experimental investigation
Universitat Jaume I (2021-12-22)Bridging the gap between experimental and computational researchers by fostering close collaborations is mandatory for making a breakthrough in the investigation of materials. The combined forces of these two pillars, ... -
Effect of strain and variable mass on the formation of antibonding hole ground states in InAs quantum dot molecules
American Physical Society (2010-10-04)Using four-band k·p Hamiltonians, we study how biaxial strain and position-dependent effective masses influence hole tunneling in vertically coupled InAs/GaAs quantum dots. Strain reduces the tunneling and hence the critical ... -
Hole spin mixing in InAs Quantum Dot Molecules
American Physical Society (2010)The spin state of holes confined in single InAs quantum dots have recently emerged as a promising system for the storage or manipulation of quantum information. These holes are often assumed to have no mixing between ... -
Improved solar water splitting performance of BiVO4 photoanode by the synergistic effect of Zr-Mo co-doping and FeOOH Co-catalyst layer
Elsevier (2022)In this work, Zr-Mo co-doping was successfully employed on electrochemically deposited BiVO4 photoanodes, and tested for photoelectrochemical (PEC) water oxidation. Zr doping induced the formation of relatively smaller ... -
Molecular Electronic Coupling Controls Charge Recombination Kinetics in Organic Solar Cells of Low Bandgap Diketopyrrolopyrrole, Carbazole, and Thiophene Polymers
American Chemical Society (2013)Low-bandgap diketopyrrolopyrrole- and carbazole-based polymer bulk-heterojunction, solar cells exhibit much faster charge carrier recombination kinetics than that encountered for less-recombining poly(3-hexylthiophene). ... -
Optical Analysis of a series of Size and Shape-controlled Type-II CdTe/CdSe/CdTe Heterostructure Nanorods
IOP Publishing (2010)wo series of size and shape-controlled type-II CdTe/CdSe/CdTe heterostructure nanorods with different geometrical structures were prepared by the colloidal sequential reactant injection technique. The samples, including ... -
Valence band mixing of cubic GaN/AlN quantum dots
Institute of Physics (2012)We study the spin purity of the hole ground state in nearly axially symmetric GaN/AlN quantum dots (QDs). To this end, we develop a six-band Burt-Foreman Hamiltonian describing the valence band structure of zinc-blende ...
