Nowadays it has become common for scientist and engineers working in micro-electro mechanical system area to simulate the structure using simulation software like COMSOL before actual fabrication. The software helps to create the structure, mesh it and then simulate. In this paper we have modeled and simulated the micro pressure sensor wish can be used to determine the environment pressure with for example piezoresistive detection. The analysis is carried out for different parameters. In this work we need to study the stress repartition on the Silicon membrane surface. This study is very important because it allows us to determinate where the stress is maximal and to place there the four piezoresistors, wish provides a maximal sensitivity to the pressure. Differing from traditional silicon piezoresistive pressure sensor, we use platinum piezoresistive pressure sensor, in wish platinium is used as the piezoresistor material of pressure sensor. We use platinium as the sensing material of pressure sensor to simplify the fabrication process to integrate pressure sensor into for example multisensor for micro wheather station.","PeriodicalId":149945,"journal":{"name":"2014 North African Workshop on Dielectic Materials for Photovoltaic Systems (NAWDMPV)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125511358","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}

These films are prepared by polymerization induced phases separation by electron-beam (EB) or ultra-violet (UV) radiation. Films obtained are characterized by a Dynamic Mechanical Thermal Analysis. The experimental results show that GPTA films have a module of conservation higher than that of TPGDA films for the two types of irradiation. Density of these films with various thicknesses is given with and without liquid crystal for to see the effect of this last on the properties of the TPGDA/E7 and GPTA/E7 systems. The presence of microdroplets of liquid crystal E7 in the matrix TPGDA or GPTA affect the density of systems studied who is weaker for the films with matrix TPGDA; this can be connected with the nature of the monomers GPTA three-functionals, what carries with films more dense.","PeriodicalId":149945,"journal":{"name":"2014 North African Workshop on Dielectic Materials for Photovoltaic Systems (NAWDMPV)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130318158","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}

To validate our approach, we compare the results of electronic properties with those obtained using the generalized gradient approximation parameterized by Perdew, Burk and Emzerhop Perdew (GGA-PBE). The frequency dependent complex dielectric function ε (ω) is calculated as well as the reflectivity and absorption coefficient. Our calculations show that the optical absorption edge to ε2xx (ω) and ε2zz (ω) are located around 3.19 eV. The structural properties, the band structure and density of states are present. The lattice constants of ZnO calculated in this study are in agreement with the experimental values and the band gap obtained by the GGA-EV yielded a broad and narrow valence band relative to GGA-PBE. Moreover, EV-GGA yielded a large separation between the states d of Zn and states p of O, thereby reducing the repulsion p-d and therefore improved the energy band.","PeriodicalId":149945,"journal":{"name":"2014 North African Workshop on Dielectic Materials for Photovoltaic Systems (NAWDMPV)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115588165","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}
