We report a first-principles study on the elastic, vibrational, and electronic properties of the recently synthesized phosphorene. By calculating the Grüneisen parameters, we evaluate the frequency shift of the Raman and infrared active modes via symmetric biaxial strain. We also study a strain-induced semiconductor-metal transition, the gap size, and the(More)
In this work, the effect of biaxial strain on the electronic band structure of monolayers of MoS2 is investigated. The effective mass of carriers under different strain values is extracted and the achieved results are discussed. For the first time, we have assessed the effect of biaxial strain on the ultimate performance of MoS2-based double gate field(More)
In this paper, the effect of uniaxial strain on the electronic properties of bilayer armchair graphene nanoribbons (BLAGNRs) is theoretically investigated for the first time. Our calculations based on density functional theory (DFT) reveal the tunable nature of the electronic properties of BLAGNRs with the application of uniaxial strain. We further explore(More)
In this paper, the effect of structural nonidealities on the electronic transport properties of ultranarrow zigzag graphene nanoribbons (ZGNRs) is systemically investigated for the first time, employing the nonorthogonal third nearest neighbor mean-field Hubbard model along with the nonequilibrium Green’s function formalism. We have evaluated the influence(More)
A theoretical analysis is presented to determine the forces of interaction between an electrically charged spherical particle and a charged plane wall when the particle translates parallel to the wall and rotates around its axis in a symmetric electrolyte solution at rest. The electroviscous effects, arising from the coupling between the electrical and(More)
A theoretical analysis is presented to determine the forces of interaction between an electrically charged cylindrical particle and a charged plane boundary wall when the particle translates parallel to the wall and rotates around its axis in a symmetric electrolyte solution at rest. The electroviscous effects, arising from the coupling between the(More)
