As the ion dose of irradiation was increased, a monotonic decrease in the reflection intensity in the ultraviolet region of the spectrum was observed, due to amorphization and macrostructuring of the Si surface. On the other hand, in the long-wavelength region, a selective reflection band appears with a maximum near 830 nm due to plasmon resonance of Ag nanoparticles synthesized during implantation.","PeriodicalId":20043,"journal":{"name":"Phosphorus Sulfur and Silicon and The Related Elements","volume":"41 1","pages":"110 - 114"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86251469","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}

Herein, ZnO-CuO nanoparticles with improved antibacterial were developed by simple double precipitation technique and their properties were studied. The bactericide ability of ZnO-CuO nanoparticles was investigated against Escherichia coli. The ZnO-CuO0.5 exhibited high activity against E.coli at high and low concentration levels. The MONPs were analyzed via FTIR, UV-visible/DRS, PL, SEM/EDS, TEM, XRD and TGA analysis. These results show the formation of hexagonal wurtzite-monoclinic phase morphology and the thermal characteristics of the ZnO-CuO nanoparticles emphasize the potential of these dual nanooxide materials. The intensity of the emission band of ZnO was decreased following the increase in the CuO concentrations and the order is as follows: CuO < ZnO-CuO0.5 < ZnO-CuO0.1 < ZnO. The co-assembled MONPs developed may function as potential candidates for advanced biomedical and industrial applications.","PeriodicalId":20043,"journal":{"name":"Phosphorus Sulfur and Silicon and The Related Elements","volume":"93 1","pages":"74 - 80"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83883581","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}

We review two important experiments on slow neutron confined propagation: in thin films and in polycapillary glass fibres.

We emphasize the general interest and possible applications of exploring short scales by means of slow neutrons, through suitable combinations of the devices involved in those two experiments.","PeriodicalId":20043,"journal":{"name":"Phosphorus Sulfur and Silicon and The Related Elements","volume":"100 1","pages":"64 - 73"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74257526","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}

In this work, in order to improve the electrical parameters of MOS transistor such as, threshold voltage and flat band voltage, we have simulated Phosphorus and Arsenic diffusion profiles in three dimensions before and after thermal annealing in a highly doped polysilicon film using the simulator Silvaco TCAD based on Pearson type IV models. The model takes into account the distribution of vacancy mechanisms and effects related to high concentrations, such as the formation of clusters to study solid solubility limit. The results have been analyzed and discussed in order to extract depth of doping (Phosphorus and Arsenic) and they have been able to optimize the silicon oxide thickness, to reduce the penetration of doping.

The highest ionic conductivity on the SBPs system is 1.01 × 10−2 S cm−1 for a sample containing 8 wt. % of PC. The system was found to obey the Arrhenius rule, where R2 ≈ 1. The dielectric studies show non-Debye behaviour for CMC-AC-PC SBPs.
