In this work we develop an electron injection model for 2D materials with linear-dispersion materials. The injected model is based on satisfying the required phase-space density of electrons. In particular, we discuss the differences between a garphene-based electron injection model and older models developed for parabolic-dispersion materials. The linear dispersion of graphene implies unexpected restrictions when developing the injection model.","PeriodicalId":168149,"journal":{"name":"2014 International Workshop on Computational Electronics (IWCE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133642336","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 real morphology has been measured using electron tomography to reconstruct the mesoporous TiO2. The geometry was inserted into a mesher and used to solve a drift-diffusion model using finite element method. The simulation is used to cast light over morphology effects in solid state dye solar cells.","PeriodicalId":168149,"journal":{"name":"2014 International Workshop on Computational Electronics (IWCE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132519961","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 becomes more complex as the process advances to 16-nm and beyond. Current approaches to generate design rules are empirical shrink and lithographic simulation. However, it is time-consuming and costly to revise design rules for performance boost and yield improvement after design rules are frozen. Early performance gains in early design rule development without cost increase and yield loss will benefit semiconductor industry. In this work, we for the first time consider 16-nm bulk FinFET standard cell performance, yield, area, and layout style simultaneously to optimize design rules to meet ITRS by using geometric programming. Optical proximity correction, and electromagnetic field and circuit simulations are performed for objective function evaluation. The result achieves more than 100%-delay and 50%-yield improvement without area change by this systematic and statistical approach.","PeriodicalId":168149,"journal":{"name":"2014 International Workshop on Computational Electronics (IWCE)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132535904","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 Non-Equilibrium Green's Functions (NEGF) method is one of the most versatile frameworks for that purpose. It can deal with quantum confinement, elastic and inelastic scattering in a seamless way. Although numerically intensive, NEGF has benefited from recent advances in computational methodologies and from the increasing availability of high-performance computers. It has now reached a level of maturity where it can be applied to industrial technologies and complement semi-classical modeling.","PeriodicalId":168149,"journal":{"name":"2014 International Workshop on Computational Electronics (IWCE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132734949","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 TCO texture was modelled using a periodic triangular profile. The width of the period was kept constant and the height is changed according to the simulated angle α. The optimum roughness for the a-Si:H/a-Si:H solar cell was obtained for α = 26°. For this angle, the current density-voltage (J-V) characteristic has a good agreement with the J-V experimental data. The optimum value of α is close to the characteristics of an Asahi U-type texture used in the manufacturing process for the TCO and it generates the maximum electron density in the intrinsic layers.","PeriodicalId":168149,"journal":{"name":"2014 International Workshop on Computational Electronics (IWCE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127254179","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}
