From X-ray diffraction of TTF-I0.71 powder prepared by a solid state reaction, the superspace group of TTF-I0.71 was determined as C2/m(α0γ)0s. The TTF-Ix thin films were also fabricated on a glass substrate. It was found that the actual composition x increased with film thickness, and reached to about 0.72 above 300 nm. The Seebeck coefficient and electrical conductivity of the films showed time-dependent change, probably due to the homogenization of iodine concentration in the film.","PeriodicalId":357009,"journal":{"name":"2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125793494","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 X-ray diffraction peaks of (Zn, Sn, Ga)As2 films which shift toward lower angle compared with that of (Zn, Sn)As2 film indicate that Ga incorporating in (Zn, Sn)As2 decrease their lattice constants. Compositional analysis by electron-probe micro analyzer (EPMA) indicated that the composition ratios of Zn to all the cation sites are smaller than that of Sn. Hall effect measurements of these (Zn, Sn, Ga)As2 thin films showed n-type conductivity. These results suggest that Ga atoms are substituted for Zn atoms more than Sn atoms and change their conduction type from p-type to n-type.","PeriodicalId":357009,"journal":{"name":"2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127530318","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}

Both the quantum confinement effect and the strain effect have been studied. We applied tensile strains on both confined and transport directions of the nanoribbon and investigated the impacts on the band gap and the effective mass. We found that the band gap and the effective mass decrease with an increasing strain. In addition, the tensile strain along the transport direction has better effect on reducing the valence band effective mass. Although the valence band edge changes from K valley to the heavier Γ valley, applying a proper strain can still improve the transport properties.","PeriodicalId":357009,"journal":{"name":"2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133113113","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}

This sensor uses strain dependent frequency change of the RTD oscillator, and the frequency delta-sigma modulation (frequency DSM, or FDSM) technique, which can convert a frequency to a digital signal with wide dynamic range and wide bandwidth. The sensor consists of an oscillator using an LC resonator and an RTD loaded on a beam of the cantilever. The cantilever was fabricated using selective wet etching of the InP substrate. In this sensor, the strain applied to the cantilever changes the current-voltage characteristics of the RTD due to the piezoelectric effect, and hence it changes the oscillation frequency. In this paper, it is demonstrated that the acoustic strain signal can be successfully detected by this sensor with noise shaping behavior, which is a unique nature of the DSM.","PeriodicalId":357009,"journal":{"name":"2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125260085","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}
