There are many different methods and numerical algorithms to approximation solutions of nonlinear Schrodinger equations [5] from simple giving satisfactory results over a sufficiently large number of operations to complex. At present solutions of boundary value problems of mathematical physics [6–12] are widely used theory of atomic functions (AF). This solution is represent as a sum of shift-scaled AF families. AFs are infinitely differentiable functions and solutions of functional differential equations (FDE). They stay an intermediate position between the splines and trigonometric and algebraic polynomials. They are smoother than splines but less smooth than the polynomial. In this work we construct AFs shift-contraction of which constitutes the solution of Schrodinger equations. On the first stage the operator method [4] solution of FDE is considered. On the second step AF building of N-variables generated by the Schrodinger equation is carried out.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134200352","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}

Reliability, degradation and breakdown of advanced gate stacks 可靠性,退化和损坏的先进门堆

{"title":"Reliability, degradation and breakdown of advanced gate stacks","authors":"E. Miranda","doi":"10.1109/MSMW.2010.5545996","DOIUrl":"https://doi.org/10.1109/MSMW.2010.5545996","url":null,"abstract":"When a metal-oxide-semiconductor (MOS) structure is subjected to electrical stress, traps or defects are progressively generated within the insulator and at the interfaces, a process that eventually leads to the formation of a filamentary path across the gate dielectric. This is the signature of dielectric breakdown and is a major reliability issue for MOSFET devices. The problem is that not all the gate stacks break down in the same way so that a detailed analysis for each particular system is required. Although the failure statistics of thin oxide layers has been shown to be consistent with percolation models of defects generation, much less is known about the physics of post-breakdown conduction. In the last decade, several models based on mechanisms such as variable range hopping, tunneling, percolation and quantum point contact conduction have been proposed to explain the electron transport through the oxide layer under such circumstances. In this presentation, we will review the physics associated with these models starting from basic oxide reliability analysis. Some circuit implications of broken down devices and current applications such as the resistive switching effect will also be discussed.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134051211","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}

In particular, within the high-frequency region, the absorption oscillates as a function of wave frequency and sample thickness. Besides, the absorption becomes sensitive to the value of the electron Fermi velocity and nontrivially depends on the electron relaxation rate. The results may be very useful for the analysis of the electromagnetic response of metal-dielectric micro- and nanostructures in the terahertz and/or infrared frequency range.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130491603","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}
