Nanostructure Physics of a Quantum Well adjacent to a tunnel barrier

Master's Thesis from the year 2014 in the subject Physics - Quantum Physics Shahjalal University of Science and Technology (Department of Physics) course: Nanostructure Physics language: English abstract: We have investigated Nanostructure Physics of a Quantum Well (QW) adjacent to a tunnel barrier. On the other side of the QW we have a barrier layer of semi-infinite thickness. The book contains thorough and complete analytical calculations leading to two transcendental equations obeyed by quasi-bound energy levels of the QW. The book also contains numerical investigation of parametric variations of the quasi-bound energy levels. The variations are quite unexpected. For some values of tunnel barrier width and height each quasi-bound energy level yields two allowed energy levels. The two equations reduce to those for isolated QW in proper limiting values of parameters. The book contains necessary background on Quantum Mechanics Microelectronics and Nanostructure Physics to enable readers assimilate the book completely.
