Multi-walled carbon nanotubes photochemistry: A mechanistic view of the effect of impurities and oxygen-containing surface groups
(Pergamon-Elsevier Science Ltd, 2018-11)
Continuous photolysis experiments and transient absorption spectroscopy were performed in combination with other techniques including HRTEM, XPS, Raman, TGA, and ESR spectroscopy, to investigate the role of residual metals ...
Experimental TDPAC and Theoretical DFT Study of Structural, Electronic, and Hyperfine Properties in (111In →)111Cd-Doped SnO2 Semiconductor: Ab Initio Modeling of the Electron-Capture-Decay After-Effects Phenomenon
(American Chemical Society, 2018-08)
In this paper we investigate the effect of Cd doping at ultralow concentrations in SnO2 both experimentally, by measuring the temperature dependence of the electric quadrupole hyperfine interactions with time-differential ...
Experimental and First-Principles Theoretical Study of Structural and Electronic Properties in Tantalum-Doped In2O3 Semiconductor: Finding a Definitive Hyperfine Interaction Assignment
(American Chemical Society, 2016-03)
In this work we present an experimental and theoretical study from first-principles of the structural, electronic, and hyperfine properties of Ta-doped In2O3 semiconductor. The ab initio electronic structure calculations ...
Solution-based synthesis of kesterite thin film semiconductors
(IOP Publishing, 2020-01)
Large-scale deployment of photovoltaic modules is required to power our renewable energy future. Kesterite, Cu2ZnSn(S, Se)4, is a p-type semiconductor absorber layer with a tunable bandgap consisting of earth abundant ...
DFT-based study of the structural, electronic and hyperfine properties of the semiconducting alloys Sn1-xTixO2: HSE06 and non-regular TB-mBJ approach
(Elsevier Science SA, 2019-11)
We present here a Density Functional Theory-based ab-initio study of the structural and electronic properties of the semiconducting alloys Sn1-xTixO2 for x in the range 0.0 (rutile SnO2) to 1.0 (rutile TiO2). The hyperfine ...
Efficient spin control in high-quality-factor planar microcavities
(American Physical Society, 2012-07)
A semiconductor microcavity embedding donor impurities and excited by a laser field is modeled. By including general decay and dephasing processes, in particular, cavity photon leakage, detailed simulations show that control ...
Carbon-13 dynamic nuclear polarization in diamond via a microwave-free integrated cross effect
(National Academy of Sciences, 2019-09)
Color-center–hosting semiconductors are emerging as promising source materials for low-field dynamic nuclear polarization (DNP) at or near room temperature, but hyperfine broadening, susceptibility to magnetic field ...
