This TL can be regarded as a “lossy” TL with a negative loss because of the negative differential resistance of the RTD. This means that the TL can amplify signals while the signal travels along the line. One of the most important points to be investigated to realize this amplifier is the stability of the circuit. We discuss stability of the TLs periodically loaded with RTDs, and show that they can be stabilized by using CRLH TL configuration. It is demonstrated that this amplifier can have a gain for wide frequency range.","PeriodicalId":197102,"journal":{"name":"2010 22nd International Conference on Indium Phosphide and Related Materials (IPRM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129797997","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 impact ionization threshold energy, Eth, is calculated while keeping the energy and momentum conservation. Then the electron transport in the unstrained and the strained InAs and InSb is investigated by using the Monte Carlo (MC) method. In both InAs and InSb, the average electron velocity, vd, increases monotonically with the electric field strength, f. The tensile strain makes the low field electron mobility, μ, higher, and vice versa, which is resulted from the dependence of the effective mass in the Γ valley, m||∗(Γ), on the strain. At the high f, many electrons are restricted within the bottom of the Γ valley because of losing most of their energy by the impact ionization, which results in keeping vd large at the high f. The tensile strain makes Eth smaller and then the impact ionization coefficient, α, larger, and vice versa. Consequently, vd at the high f becomes larger under the tensile strain and smaller under the compressive strain.","PeriodicalId":197102,"journal":{"name":"2010 22nd International Conference on Indium Phosphide and Related Materials (IPRM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125755674","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 results from InP:S growth shows that the boundary plane of the grown layer has a major impact on the luminescence, indicating preferential orientation-dependent doping. Moreover, although there is clear evidence that most of the threading dislocations originating in the InP seed layer/Si interface are blocked by the mask, it appears that new dislocations are generated. Some of these dislocations are bounding planar defects such as stacking faults, possibly generated by unevenness in the mask.
