The different stoichiometry of SiNx layer (x = 0.9 and × = 1.4) was obtained by changing the ratio of the SiH2Cl2/NH3 flow rates during deposition of silicon nitride active layer (8/1 and 1/8, respectively). The spectroscopic ellipsometry measurements show the refractive index as well as absorbance could be controlled by × adjusting. As a result, it could tune the emission colour of the deposited structures by changing their chemical composition. The structures with Si-rich and N-rich SiNx active layers emit in the red (1.9 eV) and blue (2.6 eV) spectral ranges, respectively. The PL intensities of the different structures with Si-rich and N-rich SiNx are comparable. Annealing effect on PL intensity is differed for structures with Si-rich and N-rich SiNx. The origin of PL and the effect of annealing treatment have been discussed.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"518 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116250056","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 of the experimental studies on the control of disperse characteristics of aluminum oxide nanoparticles by introduction the atoms of low-ionized additives into the system are presented. It is shown that the producing the nanostructures of aluminum and zinc oxides by the same method - gas-disperse synthesis - has fundamental differences. This difference is due to the peculiarity of a zinc burning process - a gaseous reaction of zinc vapor and oxygen is impossible. Therefore, the zinc nanostructures grow quite differently and for their producing another methods of controlling their size and shape are required.","PeriodicalId":239169,"journal":{"name":"2018 IEEE 8th International Conference Nanomaterials: Application & Properties (NAP)","volume":"276 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116849340","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}

It was found that the films of both of the alloys are nanocrystalline and crystallize in two-phase (FCC and BCC)solid solutions. IB of the films of both compositions in the range of Ei=(0–300 eV)affects its composition and structure. The films deposited under IB with Ei ~300 eV are markedly depleted in Cu for CoCrCuFeNi or both in Cu and Mn for CrCoCuFeMnNi alloys, while the composition of films deposited without IB coincides with that of the target. An increase of the energy delivering to the growth surface (an increase of Idand/or Ub)promotes the surface temperature rise that leads to the grain size growth and film texturing. A noticeable decrease of the BCC phase volume in films deposited at Ub= −300 V was also observed.

It was justified experimentally that MA of Al-Cu-Ni-Fe-Cr powder mixture during 5 hours resulted in a single-phase nanocrystalline HEA with a structure of bcc solid solution. During thermal annealing recovery and recrystallization of the bcc solid solution take place at temperatures ranging from 130 to 500 °C, and phase transformation, and grain growth of equilibrium phases occur at higher temperatures. The phase composition transforms to bcc and fcc solid solutions when the MA powder was annealed at 600 °C for 1 h. The bcc and fcc solid solution structure can be maintained even after the alloy was annealed at 1000 °C. The alloy powder was consolidated by pressure sintering at 800 °C with 5 GPa pressure.
