Zero-differential resistance state of two-dimensional electron systems in strong magnetic fields.
We report the observation of a zero-differential resistance state (ZDRS) in response to a direct current above a threshold value I>I th applied to a two-dimensional system of electrons at low temperatures in a strong magnetic field. Entry into the ZDRS, which is not observable above several Kelvins, is accompanied by a sharp dip in the differential resistance. Additional analysis reveals an ins...
متن کاملSpin-ordering and magnon collective modes for two-dimensional electron lattices in strong magnetic fields.
We study the spin-ordering and the magnon collective modes of the twodimensional Wigner crystal state at strong magnetic fields. Our work is based on the Hartree-Fock approximation for the ground state and the timedependent Hartree-Fock approximation for the collective modes. We find that the ground state is ferromagnetic, i.e., that all spins are aligned at T = 0 even when the electronic g-fac...
متن کاملLow-frequency conductivity of a nondegenerate two-dimensional electron liquid in strong magnetic fields
We study the conductivity of a nondegenerate two-dimensional electron liquid in a quantizing magnetic field for frequencies well below the cyclotron frequency. The conductivity is formed by electron transitions in which the energy of a photon goes to the interaction energy of the many-electron system, whereas the involved momentum is transferred to the quenched disorder. The conductivity peak i...
متن کاملThomas-Fermi Screening in Graphene
The in-plane static screening of the field originated by a charge placed in a graphene sheet is investigated. A self-consistent field equation in the real space domain is obtained by using a suitable Thomas-Fermi procedure. Exact and approximated (for qualitative considerations) solutions are presented. In the case of a charged sheet, the screened potential presents a tail dependent on the free...
متن کاملTwo Dimensional Systems in Solid State and Surface Physics: Strong Electric and Magnetic Fields Effects
Two-dimensional condensed matter systems provide a fertile ground for the study of strong magnetic and electric field effects. We review the present status of studies in three such systems the electron space-charge layer at the semiconductor surface in a metaloxide-semiconductor (MOS) system, in heterojunction superlattices, and at the surface of liquid helium. In addition, we present the resul...
