Abstract :
The confined states in [001]-oriented strained silicon layers embedded in oxide are investigated using dasiafull-zonepsila k.p analysis within the envelop function approximation and Tight-Binding (TB) model. Calculations of important transport parameters - energy band shifts and transport masses - show new results, rising the issues of the limit of simple models like the Effective Mass Approximation (EMA).
