Resonant tunneling in double-quantum-well triple-barrier heterostructures.
We present a low-temperature ~mK! magnetotransport study, using intense pulsed magnetic fields to 50 T, of two double GaAs quantum well, triple AlAs barrier resonant tunneling structures, which demonstrates the critical influence of the second quantum well on the tunneling behavior. We show that charge accumulation in the first well, and thus the overall tunneling characteristic, is controlled ...
متن کاملHigh magnetic field tunneling transport in a double quantum well-triple barrier resonant tunneling diode
We have measured the magnetotransport of double GaAs quantum well-triple AlAs barrier resonant tunneling heterostructures in pulsed magnetic fields up to 48 T, and temperatures down to 0.3 K. The tunneling structure is designed for a near-simultaneous (triple) resonance, under bias, of the quantum well energy levels and the lowest quasi-2D emitter state. The fan chart of the I(V) resonances is ...
متن کاملCurrent fluctuations in double-barrier quantum well resonant tunneling diodes
The measurements of the spectral intensity of the current fluctuations in double-barrier quantum well resonant tunneling diodes as a function of temperature and bias current are reported. Two types of devices were studied: one with AlAs barriers and GaAs well and contact regions, and the other has Alo,,Gae,As barriers. The frequency range covered is 1 Hz-100 kHz and the temperature range is 78-...
متن کاملTheoretical Computation of Transmission Coefficient of Double Quantum Well Triple Barrier Structure in Presence of Electric Field
A numerical computation for determination of transmission coefficient of a double quantum well triple barrier structure is carried out considering GaAs/AlxGa1-xAs material composition for finite contact barrier thickness to estimate the probability of resonance at specific energy values less than barrier potential in presence and absence of electric field using transfer matrix technique. Barrie...
متن کاملPricing Double Barrier Options: An Analytical Approach
Double barrier options have become popular instruments in derivative markets. Several papers have already analysed double knock-out call and put options using di erent methods. In a recent paper, Geman and Yor (1996) derive expressions for the Laplace transform of the double barrrier option price. However, they have to resort to numerical inversion of the Laplace transform to obtain option pric...
