Abstract : Multi-dimensional heterostructures, such as quantum well wires (QWWs), have been theoretically predicted to have numerous attractive aspects, which lead workers to many attempts at fabricating them. Although several quantum confinement effects have been confirmed for conventional quantum well films (QWFs), for example, blue shifts of photoluminescence (PL) energy or observation of newly appeared quantized levels, there are almost no systematic data on QWWs. The reason for this is two fold. First of all, it is extremely difficult to fabricate optically-active QWWs which are small enough to exhibit lateral confinement effects and even if this difficulty is overcome, we are then forced with the task of systematically varying QWW size so as to examine these effects.
