A layer of silver nanoparticles is deposited on the top of the InGaN/GaN quantum wells (QWs) in gas-phase. The coupling of spontaneous emission from InGaN QWs into the surface plasmon modes of silver nanoparticle layer is demonstrated. The effect of the silver nanoparticle arrays on the extraction efficiency of the emitted light is also investigated. We show that the nanoparticles on-top layers can be used to enhance the light output of LEDs either by increasing the internal quantum efficiency through surface plasmon coupling or by increasing the light extraction efficiency through near field interaction with the evanescent field induced by the total internal reflection of the light.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127520690","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}

Nevertheless, few papers analyzed the characteristics of surface roughness nanostructures that contribute to the SERS. Thus, this paper investigates the characteristics of the corrugated polystyrene bead (PSB) array etched by a series of oxygen plasma etching time for giving a criterion to fabricate appropriate SERS-active nanoparticles. Three factors were considered in this paper: (1) the effect of plasma coupling among neighboring particles, (2) the vertical surface roughness of nanocorrugations, and (3) the pitch size, the lateral surface roughness, of nanocorrugations. By the analysis of SEM and AFM images, those factors were quantifiable. The correlation coefficient between each factor and SERS Raman enhancement was also investigated to verify that the pitch size of nanocorrugations (ranging from ~6 nm to ~12 nm on the surface of PSBs) dominates the SERS enhancement. Therefore, the maximum improvement of Raman intensity that derives from surface roughness treatment is 12 times compared to smooth surface. Moreover, it has a high enhancement factor of ~106.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124037307","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}

Three main parameters, i.e. density, height and width, are defined and used to describe black silicon and can be extended to several other parameters, such as aspect ratio, duty ratio and so on. By means of these parameters we can also establish a standard modal to provide the very basic data for other kind of research. So a program is developed to achieve these parameters expediently and accurately. Then we discuss the influence of the process parameters to surface topography and finally obtain a group of optimum parameters to fabricate black silicon. Through these results we are expecting to get better cognition of black silicon and form more controllable surface structures for mass production of black silicon.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125612106","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 paper, the Q spoiling factors are demonstrated experimentally to show the Q spoiling which originated from the water and the particulate in the surroundings. Then we propose and realize the Q maintenance through constructing a sealed and packaged microcavity regime. In the packaged structure the Q decreases a little but a high Q larger than 106 can be achieved continuously. Moreover, the sealed structure has good performance to maintain the high Q for a long time with the standard deviation about 104, because the Q spoiling factors are isolated by the package layer. Additionally, the package also enhances the robustness. These merits can promote the practical application of the microcavities.","PeriodicalId":156839,"journal":{"name":"2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125637789","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}

Opposite nonlinear behaviors (spring softening and spring hardening) are detected in devices with same dimensions and driving mechanism but different crystalline orientations ([110] and [100]) indicating the material nonlinearity dominance.
