Piezoelectric (PZT) energy harvesters (EHs) and sensors have been studied extensively and used for such application. One of the main application requirements is to design a cheap and robust system with flexibility to work with different PZT EHs without adjusting the circuit, enabling low-cost system upgrade or maintenance. This work aims at providing a low-cost and easily-maintainable solution to build wireless sensor network (WSN) for real-time electricity grid monitoring. This paper presents the design and integration of a self-contained, noninvasive system tested with two types of PZT EHs. The system is powered by EH, thus battery-less. The customized interface circuitry is designed to collect and regulate the energy from the EH. The dynamic power management ensures the system to work with two different EHs at a wide range of output power from micro-watt to milli-watt. The unit can achieve a read-transmit duty cycle from < 1min up to 18min, depending on the characteristics of different EHs and intensity of current passing through the wire being monitored, and is robust against unstable power input.","PeriodicalId":425521,"journal":{"name":"2018 IEEE 18th International Conference on Nanotechnology (IEEE-NANO)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134620782","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}

Efficient and accurate vetting of these compounds for a range of properties has recently been accomplished in high-throughput studies by use of statistical learning methods. Here we demonstrate how one such property, the fundamental bandgap, can be predicted for a family of inorganic mixed halide perovskites using fingerprints based solely on the atomic arrangement of the unit cell. Important trends and experimentally accessible factors controlling this property are thereby illuminated in a chemically intuitive manner.","PeriodicalId":425521,"journal":{"name":"2018 IEEE 18th International Conference on Nanotechnology (IEEE-NANO)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131010052","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}

Colloidal nickel nanocrystals are spin coated over silicon dioxide wafer to understand the spin coating process reliability for memory device fabrication. Spin coated wafer surface is studied using atomic force microscopy and energy dispersive X -ray characterization methods. The synthesized nanocrystals are used for fabrication of non-volatile memory devices using spin coating process.

Finite-difference time-domain (FDTD) simulations were carried out for solar cells containing nanostructures on the back side and on the front side of the solar cells, and an improvement in the performance of the solar cells was compared for the different geometries of these nanostructures. FDTD simulation results demonstrate a broadband absorption enhancement in the active-medium after employing a combination of Ag nanodiscs and ITO nanogratings. The Ag NDs lead to an enhanced surface plasmon-based scattering of longer wavelengths of light, while the ITO NGs lead to enhanced scattering of shorter wavelengths of light. This leads to a significant enhancement in optical absorption in the active medium, as well as in the short circuit current density, $mathrm{J}_{text{sc}}$, of these solar cells.","PeriodicalId":425521,"journal":{"name":"2018 IEEE 18th International Conference on Nanotechnology (IEEE-NANO)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125757147","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}
