Transmission Probability in Double Quantum Well with Triple Barrier

Quantum well of AlGaAs/GaAs is very important to study transport properties of electrons due to its wider application in electronic devices. Hence, the double well of AlGaAs/GaAs with triple barrier is taken to study transmission probability. Transmission probability is found to decrease with the increase in the height and width of the barrier. Transmission probability with energy of electron shows two peaks while taking all three barrier of the same height. Whereas a single and higher value of peak is found when the height of the central barrier is slightly reduced.
