Mesopiezoresistive 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 کاملAnalytical Expression for the Tunneling Time in Symmetrical Rectangular Double-Barrier Structures
An analytical expression for the electron tunneling time has been derived for symmetrical rectangular double-barrier structures. It gives values of the tunneling time equal to those calculated by the dwell time method for the resonant tunneling state. The obtained tunneling time is given by the sum of the time connected with the barrier layer width and the time connected with the well layer wid...
متن کاملQuantum noise in ac-driven resonant-tunneling double-barrier structures: Photon-assisted tunneling versus electron antibunching
We study the quantum noise of the electronic current in a double-barrier system with a single resonant level. In the framework of the Landauer formalism, we treat the double barrier as a quantum coherent scattering region that can exchange photons with a coupled electric field, e.g., a laser beam or a periodic ac bias voltage. As a consequence of the manifold parameters that are involved in thi...
متن کاملResonant Tunneling in Double Superlattice Barrier Heterostructures
We have invest igated resonant tunnel ing in double barr ier heterostructures in which the tunnel barr iers have been replaced by short period superlattices, and have shown for the first t ime quantum well confinement in a s ingle quantum well bounded by superlattices. These results also demonstrate the first u t i l iza t ion of shor t period b ina ry super la t t ices as effective t unne l ba...
متن کاملValuing Double Barrier Options with Time-Dependent Parameters
Based upon the Fourier series expansion, we propose a simple and easy-to-use approach for computing accurate estimates of Black-Scholes double barrier option prices with time-dependent parameters. This new approach is also able to provide tight upper and lower bounds of the exact barrier option prices. Furthermore, this approach can be straightforwardly extended to the valuation of standard Eur...
