Spin Relaxation at Graphene Nanoribbons in the presence of Substrate Surface Roughness
Zahra Chaghazardi, Shoeib Babaee Touski, Rahim Faez +1
In this work spin transport in corrugated armchair graphene nanoribbons (AGNR) is studied. We survey combined effects of spin-orbit interaction and surface roughness, employing the…
Doped Silicon Quantum Dots as Sources of Coherent Surface Plasmons
Sadreddin Behjati Ardakani, Rahim Faez
In the present work, we propose using doped Silicon Quantum Dot (SiQD) as a source of coherent surface plasmons (SPASER). The possibility of spasing in single SiQD is investigated…
Spaser Based on Graphene Capillary
Sadreddin Behjati Ardakani, Rahim Faez
In this paper, we propose a structure for graphene spaser and develop an electrostatic model for quantizing plasmonic modes. Using this model, one can analyze any spaser consisting…
A Tunable Spherical Graphene Spaser
Sadreddin Behjati Ardakani, Rahim Faez
In this work, a new structure is suggested for spasing. The presented spaser is made up of a graphene nanosphere, which supports localized surface plasmon modes, and a quantum dot…
Calculation of Confined Phonon Spectrum in Narrow Silicon Nanowires using the Valence Force Field Method
Hossein Karamitaheri, Neophytos Neophytou, Mohsen Karami Taheri +2
We study the effect of confinement on the phonon properties of ultra-narrow silicon nanowires of side sizes of 1-10nm . We use the modified valence force field method to compute th…
Engineering Enhanced Thermoelectric Properties in Zigzag Graphene Nanoribbons
Hossein Karamitaheri, Neophytos Neophytou, Mahdi Pourfath +2
We theoretically investigate the thermoelectric properties of zigzag graphene nanoribbons in the presence of extended line defects, substrate impurities and edge roughness along th…
