Peculiar Hot Electron Effects in Crossed Electric and Magnetic Fields
Hot carrier effects expected (in some cases observed) in crossed electric (both static and microwave) and magnetic (not quantum) fields are surveyed. The case that the carrieroptical phonon interaction is strong compared with the other scattering processes is of main concern. In static electric fields, the principal effect is the carrier accumulation in a special region of the momentum space wh...
متن کاملPropagation in crossed electric and magnetic fields: The quantum source approach
The propagation of electrons in static and uniform electromagnetic fields is a standard topic of classical electrodynamics. The Hamilton function is given by a quadratic polynomial in the positions and momenta. The corresponding quantummechanical problem has been analyzed in great detail and the eigenfunctions and time evolution operators are well-known. Surprisingly, the energy-dependent count...
متن کاملMeasurement of Electron Transport in Liquid Argon in Crossed Electric and Magnetic Fields
We report on a measurement of excess electron drift properties in liquid argon in the presence of crossed electric and magnetic fields. The electric field strength was varied between 6 and 110 V/cm. Using a superconducting solenoid magnetic field strengths up to 5 T were achieved. The mag_netic field 8 was oriented perpendicular to the electric field E and the components of the drift velocity G...
متن کاملGraphene nanoribbons in criss-crossed electric and magnetic fields.
Graphene nanoribbons (GNRs) in mutually perpendicular electric and magnetic fields are shown to exhibit dramatic changes in their band structure and electron-transport properties. A strong electric field across the ribbon induces multiple chiral Dirac points, closing the semiconducting gap in armchair GNRs. A perpendicular magnetic field induces partially formed Landau levels as well as dispers...
متن کاملEnhanced Dielectronic Recombination in Crossed Electric and Magnetic Fields
The dependence of the dielectronic reconbination (DR) cross section on crossed electric and magnetic fields is described. The enhancement of this cross section due to a static electric field is further increased when a magnetic field is added perpendicular to the electric field. Calculation of this field induced enhancement is presented for a realistic atomic model and the mechanism for the enh...
