چکیده

Advanced integrated circuit processing requires detailed modeling of each stage of the fabrication, to provide input for two-dimensional device models. This paper summarizes the various methods that are available for calculating ion implantation profiles in two dimensions, comparing the generality and expense of each approach. Some problems remain in modeling channeling and in verifying the results directly. Examples illustrate the range of problems that can be tackled successfully and the information that can be obtained.

Calculation of total dose and dose equivalent distribution in the treatment of lung cancer using MR-guided carbon therapy

Nowadays, in order to improve the accuracy of treatment in radiation therapy, there are many attempts to use magnetic resonance imaging (MRI) due to the advantages of excellent soft tissue contrast and ultra-fast pulse sequences. On the other hand, carbon-ion radiation therapy is developing rapidly due to the benefits of greater relative biological effectiveness (RBE) and the application in the...

Thermodynamic Study of the Ion-Pair Complexation Equilibria of Dye and Surfactant by Spectral Titration and Chemometric Analysis

Surfactant-dye interactions are very important in chemical and dyeing processes. The dyes interact strongly with surfactant and show new spectrophotometric properties, so the UV-vis absorption spectrophotometric method has been used to study this process and extract some thermodynamic parameters. In this work, the association equilibrium between ionic dyes and ionic surfactant were studied by a...

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions

By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

Ion Exchange Column Performance Model for Separation of Zr(IV) and Hf(IV) in Elution Process

A mathematical model of sorption of Zirconium and Hafnium cations mixture and elution of these ions from a cation exchange resin bed is developed. Sulfuric acid is selected as the eluent for selective separation of Zr and Hf in a packed bed of Dowex cation exchange resin. The column model is a dispersed plug flow model,and assumed to consist of randomly packed synthetic and spherical resin ...
