RRAM has fascinated researchers due to its simple structure, lower switching voltages, high density, fast switching speeds and feasible integration into CMOS processing. Transition-Metal-Oxides have been shown to be brilliant materials for RRAM applications. Among them ZnO is one the most promising materials owing to its being fab-friendly feature, having dielectric constant (k=10). A thin film of ZnO was deposited on ITO coated glass substrate by RF sputtering using radio frequency of 13.5 Mhz and Ar as carrier gas where the substrate to target distance is 7cm and Substrate rotation is 10 rpm. The RF power is 100W. The deposition rate is 0.2-0.3 A°/S. Thickness of the ZnO film was determined to be 100 nm by Rutherford backscattering using 2 MeV alpha particles from Pelletron accelerator. The I-V characteristics of the above sample was performed by using probe station (two probe mode) with pressure contact made of W metal using Keithley 6517b electrometer at IUAC, Delhi.

Firstly, one single antenna is optimized then bottom-up optimization (BUO) method has been implemented by increasing the number of single antennas, sequentially. The proposed method leads to automatically find an optimal array by setting the distance between single antennas. The optimization method is performed in an automated environment with the help of an electronic design automation (EDA) tool and a numerical analyzer. The results of the final design have been compared by means of two EDA tools such as ADS and HFSS. The optimized array antenna works in the frequency band from 12.9 GHz to 14.3 GHz. It offers a linear gain performance higher than 7.5 dB. The simulations in both ADS and HFSS tools illustrate a good match in S-parameter and gain simulation output results.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"472 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123053156","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 main emphasis in these requirements is on the repeatability of the parameters of the output pulses. In the case of operation at the peak power of the laser diode, if only a short-term excess of the upper range of the permissible current is reached, damage or failure of the laser diode is unavoidable. As the laser diode is used, its characteristics gradually impair - the radiation power decreases and, in the end, it fails. This is due to the gradual destruction of the structure of the laser diode Similarly, this includes the versatility of the housing and the efficiency of the power source. The power source monitors the power supplied and the necessary protection of expensive laser diode arrays using functions such as soft start and temperature protection. This article will describe the principles of the basic techniques for protecting laser diode arrays and the characteristics of transients, ripple currents.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125266781","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 rapidly splits into nanoparticles with a dose increase. Monatomic P ion irradiation transforms the gold layer into nanoparticles at all doses. This process is less effective that was found for ion-beam-induced Au layer dewetting on the SiO2 substrate. Healing of nanopores in the PMMA under PF4 ion bombardment is observed.
