Quantum well heterostructures comprising ZnO wells sandwiched within MgZnO barriers have been investigated through Kronig Penny Model. The carrier density has been obtained through self consistent solutions of Schrödinger and Poisson equation. The optical gain obtained for ZnO/MgZnO quantum well structure was 4113 (cm-1) for Mg mole fraction of 30% with carrier density 3.9 ×1018 cm-3. The probability density shows a good confinement in the quantum well region for well width of 5 nm considering 30% of Mg composition in the barrier. Peak value of optical gain was found to be maximum for higher value of carrier density as expected.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
