Donut and dynamic polarization effects in proton channeling through carbon nanotubes
D. Borka, D. J. Mowbray, Z. L. Miskovic +2
We investigate the angular and spatial distributions of protons of the energy of 0.223 MeV after channeling through an (11,~9) single-wall carbon nanotube of the length of 0.2 m…
Plasmon excitations on a single-wall carbon nanotube by external charges: two-dimensional, two-fluid hydrodynamic model
D. J. Mowbray, S. Segui, J. Gervasoni +2
We present a quantization of the hydrodynamic model to describe the excitation of plasmons in a single-walled carbon nanotube by a fast point charge moving near its surface at an a…
Designing multifunctional chemical sensors using Ni and Cu doped carbon nanotubes
D. J. Mowbray, J. M. Garcia-Lastra, K. S. Thygesen +2
We demonstrate a "bottom up" approach to the computational design of a multifunctional chemical sensor. General techniques are employed for describing the adsorption coverage and r…
Tailoring electronic and optical properties of TiO2: nanostructuring, doping and molecular-oxide interactions
L. Chiodo, J. M. García-Lastra, D. J. Mowbray +2
Titanium dioxide is one of the most widely investigated oxides. This is due to its broad range of applications, from catalysis to photocatalysis to photovoltaics. Despite this larg…
Trends in Metal Oxide Stability for Nanorods, Nanotubes, and Surfaces
D. J. Mowbray, J. I. Martinez, F. Calle-Vallejo +4
The formation energies of nanostructures play an important role in determining their properties, including the catalytic activity. For the case of 15 different rutile and 8 differe…
Stability and Electronic Properties of TiO2 Nanostructures With and Without B and N Doping
D. J. Mowbray, J. I. Martinez, J. M. García-Lastra +2
We address one of the main challenges to TiO2-photocatalysis, namely band gap narrowing, by combining nanostructural changes with doping. With this aim we compare TiO2's electronic…
