In this work a modified Ge-condensation technique in which Ge ions were implanted into a top silicon layer was proposed. Through a cyclic dry oxidation and annealing steps, ∼20 nm thick, single crystalline Ge layer could be obtained. X-ray diffraction and Raman scattering analyses also confirmed that the layer was fully-relaxed, which is desirable for the integration of Ge, GaAs, and strained silicon on the GeOI.","PeriodicalId":129653,"journal":{"name":"2010 Conference on Optoelectronic and Microelectronic Materials and Devices","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115777789","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}

The properties of the bistablility such as the hysteresis area, the onset and damaged threshold intensities are shown to be porosity dependent. Our model suggests that the bistability is due to the induced nonlinear refractive index changes and the transient lifetime increases with increasing porosity. The role of surface states in the bistability process was also investigated by passivating the internal porous surface using the hydrosilylation chemistry.","PeriodicalId":129653,"journal":{"name":"2010 Conference on Optoelectronic and Microelectronic Materials and Devices","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129531019","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}
