The I-V behaviour of the material is different if Fe concentration is below or above 1.5/spl times/10/sup 17/ cm/sup -3/. Differential resistivity derived from these curves also exhibits a maximum at Fe=1.5/spl times/10/sup 17/ cm/sup -3/. These observations indicate that the cause of semi-insulation may be different below and above this concentration. It is suggested that Fe may be mostly site incorporated in the low concentration regime and mostly in the form of Fe-P complexes in the high concentration regime, A GaInP/GaInAsP/GaAs buried heterostructure with semi-insulating Ga/sub 0.51/In/sub 0.49/P:Fe regrowth has been fabricated for the first time to demonstrate the usefulness of the investigated material in device fabrication.","PeriodicalId":391894,"journal":{"name":"Proceedings of Semiconducting and Semi-Insulating Materials Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126163325","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}

We study the gap opening according to whether the dielectric constant of the cylinders is larger or smaller than that of the background.
