Structural details of Al/Al2O3 junctions and their role in formation of electron tunnel barriers
M. Koberidze, M. J. Puska, R. M. Nieminen
We present a computational study of the adhesive and structural properties of the Al/Al2O3 interfaces as building blocks of the Metal-Insulator-Metal (MIM) tunnel devices, where el…
Pick-off annihilation of positronium in matter using full correlation single particle potentials: solid He
A. Zubiaga, F. Tuomisto, M. Puska
We investigate the modeling of positronium (Ps) states and their pick-off annihilation trapped at open volumes pockets in condensed molecular matter. Our starting point is the inte…
Matter-positronium interaction: An exact diagonalization study of the He atom - positronium system
A. Zubiaga, F. Tuomisto, M. J. Puska
The many-body system comprising a He nucleus, three electrons, and a positron has been studied using the exact diagonalization technique. The purpose has been to clarify to which e…
Local Semiconducting Transition in Armchair Carbon Nanotubes: The Effect of Periodic Bi-site Perturbation on Electronic and Transport Properties of Carbon Nanotubes
M. J. Hashemi, K. Sääskilahti, M. J. Puska
In carbon nanotubes, the most abundant defects, caused for example by irradiation or chemisorption treatments, are small perturbing clusters, i.e. bi-site defects, extending over b…
