Real space transfer transistor(RSTT) is a novel N-type negative differential resistance semiconductor device which has some obvious characteristics,such as high frequency,high speed and controllable NDR. In this paper,we explain the operating principle of RSTT,summarize the development of RSTT on material,structure and performances,and introduce its application in areas of logic unit,photoelectric integration and so on. Finally,the research emphases of this kind of devices are prospected.
