We have a created a photodiode with a reduced dead layer entrance window. Existing photodiodes are limited in sensitivity for low wavelengths due to the low penetration depth of photons of < 400 nm. Typical photodiodes have a junction implant which causes the low penetrating photons to be recombined in this dead layer. Here, we have utilized the near transparent nature of single layer graphene to create a junction with a minimum dead layer. To have a full active bulk volume we have combined a single junction ring (n++ bias ring) with single layer graphene. The graphene acts as a large field plate which overhangs the junction ring, on top of a thin dielectric, and covers the entire active area, 5×5 mm 2. Transient Current Technique measurements have been performed to study the charge uniformity of the device and it has been shown that the charge collected is 100% across the entire area of the detector. Additional characterisations have been performed to evaluate the sensitivity of the device as a function of wavelength in comparison to a device with an ultra-shallow junction implant. The results show that the graphene-enhanced device shows far greater performance in the 200–400 nm wavelength range.","PeriodicalId":146643,"journal":{"name":"2022 IEEE 22nd International Conference on Nanotechnology (NANO)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116946510","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, we have developed a bio modified Carbon-Microelectromechanical Systems (C-MEMS) derived glassy carbon electrode (GCE) to detect bacterial cellsin their lag as well as log phases of growth using non-faradaic electrochemical impedance spectroscopy (nf-EIS) measurements. The absence of any labeling molecule and the use of no redox indicators make the measurement system simpler and more precise. The investigations were carried out to detect Shigella bacteria concentrations in the growth milk medium. The electrode is bio modified using silver nanoparticles (AgNPs) which are green synthesized using Azadirachta indica. This paper highlights the synthesis of AgNPs as well as its characterization using standard analytical techniques. The synthesized nanoparticles have been proven as an antibacterial agent using standard bioassay technique and this has been employed to detect the decrease in cell concentration using nf-EIS. These results help pave the way for rapid antibacterial testing at the point-of-need, which is currently a major challenge in water quality control. The biosynthesized AgNPs enhance bacteria detection and the preliminary results obtained is satisfactory. It can be concluded from the results that the Glassy Carbon sensor is a potential candidate for water quality monitoring application and our present research is in line with that.","PeriodicalId":146643,"journal":{"name":"2022 IEEE 22nd International Conference on Nanotechnology (NANO)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124828719","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}

However, this method not only results in long latency and thus increases energy consumption, but also reduces computing accuracy. Fortunately, stochastic bitstreams can be generated in parallel to reduce the latency. In this paper, parallel and serial multipliers using optimized encoding sequences with high accuracy and low energy consumption are proposed. Experimental results show that the mean squared error (MSE) is only 0.0015 for a 3-bit serial/parallel multiplier. The MSEs of 3-to 8-bit multipliers are reduced by approximately 29% on average compared with existing designs. The serial multiplier reduces the area and energy consumption by approximately 28% and 24% on average. The parallel multiplier reduces the latency and energy consumption by about 78% and 57% on average, respectively. To evaluate the effectiveness of the proposed multipliers, an image multiplication algorithm is implemented. The results show that the proposed multipliers yield higher image qualities than previous designs.","PeriodicalId":146643,"journal":{"name":"2022 IEEE 22nd International Conference on Nanotechnology (NANO)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123801963","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 array of Bessel beams with multiple orders is generated by utilizing geometric metasurfaces to have full phase control over the optical properties of light. In prior works, Bessel beams are realized with optical metasurfaces of titanium dioxide (TiO2) and gallium nitride (GaN) but they have bottlenecks in terms of complex and expensive fabrication. Here, in this manuscript, we have represented a single-layer optical metasurface based on gallium phosphide (GaP) for Bessel beam generation. The proposed metasurface has high transmission efficiency in the visible regime and is capable of producing four Bessel beams of arbitrary orders without the accumulation of extra complexities in conventional nano-rectangular pillar geometry. Due to the property of orbital angular momentum, these arbitrary order Bessel beams have a high capacity for data storage. Thus, they provide an appropriate platform for numerous interesting phenomena of data encryption and information storage.","PeriodicalId":146643,"journal":{"name":"2022 IEEE 22nd International Conference on Nanotechnology (NANO)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116524485","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}
