WKB method applied to Nanostructure Physics

The work provides a thorough illustration of use of WKB method to barrier transmission problem. On reading the book, the reader will be adept in using the method. Single and symmetric double barriers of general shape are treated first. Then single and symmetric double barriers of many different shapes we encounter in studying Nanostructure Physics are covered. Complete analytical calculation and results of extensive numerical investigation are reported along with comparison with standard results where available showing excellent agreement.
