The growing curves are obtained in the entire investigated temperature range for both doping level. They are explained within the mechanism of thermionic current flow through metal shunts associated with the so-called conducting dislocations. Good agreement between the theoretical and experimental dependences is obtained assuming that the flowing current is limited by total resistance of metal shunts. Moreover the effect of temperature dependence of metal resistivity on total contact resistivity was observed. The density of conducting dislocations obtained from the theory is coherent with the density of screw and edge dislocations obtained from X-ray diffraction investigation of the structure.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"1 1","pages":"01PCSI20-1-01PCSI20-3"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91359607","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}

Scanning electron microscopy and high-resolution x-ray photoemission spectroscopy were used for structural characterization of CNx films on quartz substrates. The corresponding structural diagram determined by the substrate temperature and nitrogen concentration in the CNx film has been built. It includes four main nanostructures: graphite-like, fullerene-like, diamond-like and nano columnar.

The main feature of the received structures is the formation of stable shear bands. Their role in the crazing development and their mutual interaction under uniaxial tension for PLA and PLA/PBS composite was investigated by in-situ tensile testing in the SEM experiments. It has been established that pre-existing shear bands contributes to ductility by blocking and diffusing standard craze growth. Moreover, PBS nanofibers, formed by extrusion, additionally confer to ductile character of PLA/PBS composites by providing pre-existing shear bands and craze rotation. Tensile experiments revealed an essential growth of ductility and retaining of high strength and stiffness of the extruded PLA and PLA/PBS composite.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"6 1","pages":"03NNSA14-1-03NNSA14-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73246881","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}
