Abstract : Multiquantum wells (MQW's) are being widely applied to various electronic and optoelectronic devices. It is of vital importance to characterize MQW structures such as period, uniformity of barrier and well layers and abruptness of hetero-interfaces as exactly as possible. A scanning tunneling microscope (STM) is considered as a useful tool to observe MQW structures with a high resolution. However, only a few data on this issue have been reported.
