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…
Enhanced Spin-Flip Scattering by Surface Roughness in WS and MoS Armchair Nanoribbons
Shoeib Babaee Touski, Rafael Roldán, Mahdi Pourfath +1
The band structures of single-layer MoS and WS present a coupling between spin and valley degrees of freedom that suppresses spin-flip scattering and spin dephasing. Here w…
The influence of non-idealities on the thermoelectric power factor of nanostructured superlattices
Mischa Thesberg, Mahdi Pourfath, Hans Kosina +1
Cross-plane superlattices composed of nanoscale layers of alternating potential wells and barriers have attracted great attention for their potential to provide thermoelectric powe…
Highly Anistoropic Thermal Conductivity of Arsenene: An ab initio Study
M. Zeraati, S. M. Vaez Allaei, I. Abdolhosseini Sarsari +2
Elemental 2D materials exhibit intriguing heat transport and phononic properties. Here we have investigated the lattice thermal conductivity of newly proposed arsenene, the 2D hone…
Low-dimensional phonon transport effects in ultra-narrow, disordered graphene nanoribbons
Hossein Karamitaheri, Mahdi Pourfath, Hans Kosina +1
We investigate the influence of low-dimensionality and disorder in phonon transport in ultra-narrow armchair graphene nanoribbons (GNRs) using non-equilibrium Greens function (NEGF…
Strain induced mobility modulation in single-layer MoS
Manouchehr Hosseini, Mohammad Elahi, Mahdi Pourfath +1
In this paper the effect of biaxial and uniaxial strain on the mobility of single-layer MoS for temperatures T 100 K is investigated. Scattering from intrinsic phonon mod…
Modulation of electronic and mechanical properties of phosphorene through strain
Mohammad Elahi, Kaveh Khaliji, Seyed Mohammad Tabatabaei +2
We report a first-principles study on the elastic, vibrational, and electronic properties of recently synthesized phosphorene. By calculating Grüneisen parameters, we evaluate the…
Engineering Enhanced Thermoelectric Properties in Zigzag Graphene Nanoribbons
