چکیده
In this study, we investigate the cyclotron resonance effect in first-order ac current, magnetic ratchet effect, and second harmonic generation phosphorene presence of a steady tilted field under THz laser radiation. We establish that various resonances exist deduced currents based on angular frequency incoming light. These are dependent ${\ensuremath{\omega}}_{{c}_{+}}$ value, function carrier charge, perpendicular field, effective masses along armchair or zigzag edges. discuss direction magnitude for radiation polarizations. compare results with zero field. Cyclotron current occurs at $\ensuremath{\omega}=\ifmmode\pm\else\textpm\fi{}{\ensuremath{\omega}}_{{c}_{+}}$. The declines if is zero. Meanwhile, occur $\ensuremath{\omega}=\ifmmode\pm\else\textpm\fi{}{\ensuremath{\omega}}_{{c}_{+}}$, $\ensuremath{\omega}=\ifmmode\pm\else\textpm\fi{}2{\ensuremath{\omega}}_{{c}_{+}}$, helicity affects circularly polarized $\ensuremath{\omega}=\ifmmode\pm\else\textpm\fi{}{\ensuremath{\omega}}_{{c}_{+}}/2$, stronger compared to case no As rotates plane anisotropic phosphorene, separate directions predicted generation--related current. It noteworthy within same range comparable monolayer graphene, $\ensuremath{\mu}\text{A/cm}$.

Ferromagnetism controlled by electric field in tilted phosphorene nanoribbon
Study on phosphorene nanoribbon was mostly focused on zigzag and armchair structures and no ferromagnetic ground state was observed in these systems. Here, we investigated the magnetic property of tilted black phosphorene nanoribbons (TPNRs) affected by an external electric field. We also studied the edge passivation effect on the magnetism and thermal stability of the nanoribbons. The pure TPN...
متن کاملMaker fringes in the Terahertz radiation produced by a 2-color laser field in air.
The terahertz radiation produced by a 2-color femtosecond laser scheme strongly saturates and develops an oscillatory behavior with increasing power of the driving femtosecond laser pulses. This is explained by the formation of a plasma channel due to filamentation. Due to dispersion inside the filament and the Gouy phase shift, the phase difference between the 800 nm and 400 nm pulses varies a...
متن کاملTerahertz radiation from a shallow incidence-angle InAs emitter in a magnetic field irradiated with femtosecond laser pulses.
The optimized incidence angle and magnetic field direction geometry of an InAs terahertz radiation emitter irradiated with femtosecond laser pulses in a magnetic field is reported. The optimum geometric layout is the magnetic field direction parallel to the semiconductor surface and at an incidence angle that is slightly larger than the Brewster angle. Additionally, we also observed a center fr...

The motion of an electron in a semiconductor superlattice, undergoing the combined action of a static magnetic field perpendicular to its growth direction and intense electromagnetic radiation is considered. Exact numerical solutions of the time-dependent Schrödinger equation are found for a superlattice with a sinusoidal potential. Quasienergies are calculated as function of the cyclotronic or...
