Title: Ultrafast optical currents in gapped graphene

Abstract

Abstract We theoretically study the interaction of ultrashort optical pulses with gapped graphene. Such a strong pulse results in a finite conduction band population and a corresponding electric current, both during and after the pulse. Since gapped graphene has broken inversion symmetry, it has an axial symmetry about the y -axis but not about the x -axis. We show that, in this case, if the linear pulse is polarized along the x -axis, the rectified electric current is generated in the y direction. At the same time, the conduction band population distribution in the reciprocal space is symmetric about the x -axis. Thus, the rectified current in gapped graphene has an inter-band origin, while the intra-band contribution to the rectified current is zero.

Topological resonance and single-optical-cycle valley polarization in gapped graphene

Journal Article Oliaei Motlagh, S. Azar ; Nematollahi, Fatemeh ; Apalkov, Vadym ; ... - Physical Review B

For gapped graphene, we predict that an intense ultrashort (single-oscillation) circularly polarized optical pulse can induce a large population of the conduction band and a large valley polarization. With an increase in the band gap, the magnitude of the valley polarization gradually increases from zero (for the native gapless graphene) to a value on the order of unity. The energy bandwidth of the electrons excited into the conduction band can be very large (≳10 eV for a reasonable pulse amplitude of ~0.5 V/Å). These phenomena are due to the effect of topological resonance: The matching of the topological (geometric) phasemore »« less

Weyl semimetals in ultrafast laser fields

Journal Article Nematollahi, Fatemeh ; Oliaei Motlagh, S. Azar ; Apalkov, Vadym ; ... - Physical Review B

We study theoretically the interaction of topological Weyl semimetals with an ultrafast optical pulse. The electron dynamics in such material is coherent and highly anisotropic. For some directions of pulse polarization, the electric dynamics is irreversible, which means that the residual electron conduction-band population after the pulse is comparable to the maximum conduction-band population during the pulse. For other directions of polarization, the electron dynamics is highly reversible and, after the pulse, the electron system returns to its initial state with almost zero conduction-band population. Such high anisotropy in electron dynamics is related to anisotropy in interband dipole matrix elements.more »« less

Absorption properties of graphene quantum dots under ultrashort optical pulses

Journal Article Oliaei Motlagh, S. Azar ; Apalkov, Vadym - Physical Review B

Here, we study the interaction of graphene quantum dots (GQDs) with ultrashort and strong optical pulses theoretically. An important characteristic of such interaction is the energy accumulated by GQDs after the pulse. We show that the GQD absorbance has a highly nonlinear dependence on the field amplitude. At small-field amplitudes, the absorbance strongly depends on the frequency of the pulse and the band gap of a QD, i.e., its size. At large-field amplitudes, ~1 V/Å, the absorbance has a weak nonmonotonic dependence on the size of the dot with its maximum value of ≈ 4.5 % realized for GQD consistingmore »« less

Ultrafast strong-field absorption in gapped graphene

Journal Article Oliaei Motlagh, S. Azar ; Zafar, Ahmal Jawad ; Mitra, Aranyo ; ... - Physical Review B

In this work, we study theoretically the strong-field absorption of an ultrafast optical pulse by a gapped graphene monolayer. At low field amplitudes, the absorbance in pristine graphene is equal to the universal value of 2.3%. Although the ultrafast optical absorption for low field amplitudes is independent of the polarization, linear or circular, of the applied optical pulse, for high field amplitudes, the absorption strongly depends on the pulse polarization. For a linearly polarized pulse, the optical absorbance is saturated at the value of ≈ 1.4% for the pulse's amplitude of ≥ 0.4 V/Å, but no such saturation is observedmore »« less

Hot electron dynamics in graphene

Thesis/Dissertation Ling, Meng-Chieh

Graphene, a two-dimensional (2D) honeycomb structure allotrope of carbon atoms, has a long history since the invention of the pencil [Petroski (1989)] and the linear dispersion band structure proposed by Wallace [Wal]; however, only after Novoselov et al. successively isolated graphene from graphite [Novoselov et al. (2004)], it has been studied intensively during the recent years. It draws so much attentions not only because of its potential application in future electronic devices but also because of its fundamental properties: its quasiparticles are governed by the two-dimensional Dirac equation, and exhibit a variety of phenomena such as the anomalous integer quantummore »« less
