Abstract

Since Esaki¹⁾ and Tsu proposed the quantum well structure, many workers²⁾ have interested in this structure in a physical and applicational points of view. In the quantum well structure the carriers are localized in one or a few quantum wells depending on well parameters such as the barrier hight, well size and well-to-well distance. Since this localization strongly affects to device performances, it is very important to understand the dynamics of localized carriers to design new devices.
