Tuning thermoelectric transport in phosphorene through a perpendicular magnetic field

We address perpendicular magnetic field effects on the electrical conductivity, electronic thermal conductivity, thermopower, and figure of merit in phosphorene. By means of continuum Hamiltonian model and the Green's function approach, we report a significant difference in the magneto-thermoelectric properties. Results showcase an irregular (regular) behavior in AC (ZZ) direction for electrical conductivity in the presence of a magnetic field. Furthermore, we found an oscillating (increasing) treatment for the Drude weight with increasing magnetic field in AC (ZZ) direction at low temperatures. Also, the electronic thermal conductivity findings introduce the ZZ direction as the right direction in thermoelectric real applications of phosphorene because electronic thermal conductivity in ZZ direction decreases with the magnetic field. In contrast to the electrical conductivity and electronic thermal conductivity, thermopower in AC direction satisfies the requirements of efficient thermoelectric properties at strong magnetic fields. These dependency aspects of the electronic transport coefficients provide insights to modulate the real applications in nanoelectronics.
