Abstract
A general theoretical formalism is developed for evaluating the lowest energy levels of an exciton in a system which is of finite size, but multiply periodic, in one dimension, whilst being of infinite extent in the other two directions. A particular application of the formalism to a Kronig-Penney type I multiquantum well-superlattice structure is made and the significance of the results described.Keywords
