Abstract

A large number of studies have been done for multiple quantum wells of inorganic semiconductor, because confined electronic system in a thin layer shows various properties essential for optoelectronic application. Since the quantum size effect increases when the electron system approaches lower dimension, fabrication of higher order confined structures has been attempted to advance the properties. On the other hand, there are many substances having one-dimensional structure in the nature. It can be thought that the one-dimensionality is prospective to realize a higher order confined system.
