Research Paper (postgraduate) from the year 2017 in the subject Physics - Quantum Physics, grade: 4.00, Shahjalal University of Science and Technology, course: Nanostructure Physics, language: English, abstract: We have investigated electron transmission through non-tunneling regime of a semiconductor nanostructure called Coupled Quantum Well (CQW). Oscillatory transmission coefficient as a function of energy is found to show spectacular waxing and waning in amplitude. Corresponding features are expected to be observed in optical (Physical Review B 54 (1996) 1541) and quantum transport (Physical Review Letters 58 (1987) 816) experiments and hence the results besides verifying the Physics will have impact on future devices based on CQW.
