Two-dimensional magnetotransport in a black phosphorus naked quantum well
Black phosphorus (bP) is the second known elemental allotrope with a layered crystal structure that can be mechanically exfoliated to atomic layer thickness. Unlike metallic graphite and semi-metallic graphene, bP is a semiconductor in both bulk and few-layer form. Here we fabricate bP-naked quantum wells in a back-gated field effect transistor geometry with bP thicknesses ranging from 6±1 nm t...
متن کاملQuantum transport theory of Weiss oscillations quenching of a two-dimensional electron gas in a strong periodic potential.
The quenching of the Weiss oscillation of magnetoresistance in a two-dimensional electron gas subjected to strong one-dimensional periodic potential is calculated nonperturbatively using quantum transport theory. The results are in good qualitative agreement with the experiment of Beton et al. @Phys. Rev. B 42, 9229 ~1990!#. The discrepancy between the classical calculation and the experiment i...

In this paper we study the Aharonov-Bohm oscillations of transmission coefficient for an electron passing through a quantum nanoring with two identical magnetic impurities using quantum waveguide theory. It is shown that the Aharonov-Bohm oscillations are independent of the coupling constant between the electron and magnetic impurities for the singlet spin state of impurities, while for the o...
متن کاملSpontaneous magnetization and electron momentum density in three-dimensional quantum dots
We discuss an exactly solvable model Hamiltonian for describing the interacting electron gas in a quantum dot. Results for a spherical square-well confining potential are presented. The ground state is found to exhibit striking oscillations in spin polarization with dot radius at a fixed electron density. These oscillations are shown to induce characteristic signatures in the momentum density o...
متن کاملTransport properties of pristine few-layer black phosphorus by van der Waals passivation in an inert atmosphere.
Ultrathin black phosphorus is a two-dimensional semiconductor with a sizeable band gap. Its excellent electronic properties make it attractive for applications in transistor, logic and optoelectronic devices. However, it is also the first widely investigated two-dimensional material to undergo degradation upon exposure to ambient air. Therefore a passivation method is required to study the intr...
