Tunneling of electrons in graphene via double triangular barrier in external fields
نویسندگان
چکیده
We study the transmission probability of Dirac fermions in graphene scattered by a triangular double barrier potential presence an external magnetic field. Our system made two regions separated well region characterized energy gap. Solving our Dirac-like equation and matching solutions at boundaries allowed us to express reflection coefficients terms transfer matrix. show particular that exhibits oscillation resonances are manifestations Klein tunneling effect. The electrostatic field was found play key role controlling peak resistance. However, it only slightly modifies oblique incidence leaves paradox unaffected normal incidence.

متن کاملNegative Differential Resistance of Electrons in Graphene Barrier
The graphene is a native two-dimensional crystal material consisting of a single sheet of carbon atoms. In this unique one-atom-thick material, the electron transport is ballistic and is described by a quantum relativistic-like Dirac equation rather than by the Schrödinger equation. As a result, a graphene barrier behaves very differently compared to a common semiconductor barrier. We show that...

متن کاملMesopiezoresistive effects in double-barrier resonant tunneling structures
This letter reports a mesopiezoresistive effect in a double-barrier resonant tunneling DBRT structure. In a DBRT system, an external mechanical stress causes a tensile strain, and the strain, in turn, affects the resonant tunneling and thereby the resistance. Theoretical analysis was carried out on an AlAs /GaAs /AlAs DBRT structure under in-plane uniaxial tensile stresses. The results show tha...
متن کاملCoherent-electron intrinsic multistability in a double-barrier tunneling diode
Recently, a new mechanism leading to electrical multistability in coherent-electron tunneling devices was proposed. The reflection of coherent electrons at a barrier leads to the formation of resonant states in a quantum well in front of the barrier, and the resulting strongly modulated local density of states allows for multiple stable solutions of the Poisson equation to exist at fixed bias. ...
