Resonant Tunneling in Photonic Double Quantum Well Heterostructures
Here, we study the resonant photonic states of photonic double quantum well (PDQW) heterostructures composed of two different photonic crystals. The heterostructure is denoted as B/A/B/A/B, where photonic crystals A and B act as photonic wells and barriers, respectively. The resulting band structure causes photons to become confined within the wells, where they occupy discrete quantized states....
متن کاملResonant 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 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 کاملProperties and Device Applications of Deep Quantum Well Resonan’i Tunneling Structures
A self-conststent quantum mechanical simulation is used to study the effects of doping, spacer layers, harrier height, harrier wdth and well doping on the bound state and bound state charge in a deep quantum well resonant tunneling structure. Experimental reaulta for the GaAs and InP heteroatructure material system are presented. Finally various device applications. such as microwaw video detec...
متن کاملUnusual Tunneling Characteristics of Double-quantum-well Heterostructures
We report tunneling phenomena in double In0.53Ga0.47As quantum-well structures that are at odds with the conventional parallel-momentum-conserving picture of tunneling between two-dimensional systems. We found that the tunneling current was mostly determined by the correlation between the emitter and the state in one well, and not by that between those in both wells. Clear magnetic-field-depend...
