- Title
Simple Quantum Confinement Theory for Exciton in Indirect Gap Nanostructures.
- Authors
Van Oanh, Nguyen Thi; Viet, Nguyen Ai
- Abstract
We propose in this work a simple quantum confinement theory for excitons based on the effective mass approximation, for investigation of optical properties of indirect gap nanostructures. We show that using this simple model, we can get the analytic solutions and reobtain the main tight-binding approximation numerical results of Hill et al. for silicon nanostructures: blue shift of band gap and increase overlap between the states at the band edges when the nanostructures size in decreased.
