The results of calculations show that in contrast to the single quantum-well case, at some values of MQW parameters the number of S-mat-rix poles may exceed that of the absolute reflection peaks, and at different values of parameters the absolute reflection peak corresponds to different resonant states. At some values of MQW parameters there is in fact a long-living over-barrier resonant hole state. Lifetimes of resonant states depend drastically on the quantum-well potential depth. In the case of sufficiently shallow quantum wells there is a single long-living resonant state.","PeriodicalId":117420,"journal":{"name":"2010 10th International Conference on Laser and Fiber-Optical Networks Modeling","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121714339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Joint action of both effects leads to the linear dependence of the transition energy on the width of the quantum well.
