Computational method Ab initio computation, which allows parameter free calculations real materials at the atomic level and focuses on the understanding and the design of new materials with superior properties and functionalities, has proven its merit. The progress over the last 20 years is largely due to the success of density-functional theory (DFT). Thus these calculations can be applied to all condensed matter systems, ranging from metals, semiconductors and insulators to complicated nanostructures.<\/span><\/h2>\n<\/header>\n<div class=\"entry-content clearfix\">\n<div id=\"attachment_339\" class=\"wp-caption aligncenter\">\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-339 size-full\" src=\"http:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/image-Wokshop-materials.png\" sizes=\"(max-width: 631px) 100vw, 631px\" srcset=\"https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/image-Wokshop-materials.png 631w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/image-Wokshop-materials-300x181.png 300w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/image-Wokshop-materials-250x151.png 250w\" alt=\"image-Wokshop-materials\" width=\"631\" height=\"381\" \/><\/p>\n<p class=\"wp-caption-text\"><b>Illustration of the multi-physics hierarchy with length and time scales for each modeling strategy including some potential technology devices for simulation and modeling<\/b><\/p>\n<\/div>\n<p>Researchers in the Laboratory of Magnetism and High Energy Physics of University Mohamed V, Rabat, have a long-standing interest in computational physics simulations.

The KKR-CPA allows direct calculation of the configurationally averaged properties of the alloy\u2014configurationally averaged DOS, charge density and Bloch spectral function (BSF). We review some recent conceptual improvements of the Korringa\u2013Kohn\u2013 Rostoker (KKR) Green function method for electronic structure calculations. After an introduction into the KKR\u2013Green function method we present an extension of this method into an accurate full-potential scheme, which allows calculation of forces and lattice relaxations.<\/p>\n<ul>\n<li><strong>The interface of KKR-CPA:<\/strong><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Installing under LINUX, Operating systems and compilers<\/li>\n<li>Running the AKAI-KKR program specx<\/li>\n<li>Input for the AKAI-KKR program specx<\/li>\n<\/ul>\n<p><strong>Objectives:<\/strong><\/p>\n<ul>\n<li>Prepare an input file for KKR-CPA, defining all the necessary parameters.<\/li>\n<li>Study the convergence of the ground state energy with respect to the cutoff energy.<\/li>\n<li>Determine the relaxed lattice constant.<\/li>\n<li>Output and plot the density of states (DOS).<\/li>\n<li>Create the \u201cout\u201d file containing complete information on the Kohn-Sham bandstructure used.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li><strong>Practical examples:<\/strong><\/li>\n<\/ul>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Al doped ZnO; Transparent Conductive Oxide<\/li>\n<li>Band-gap engineering of SnO2: controlling the band structure and optoelectronic properties of few-layer SnO2\u00a0via strain engineering<\/li>\n<\/ul>\n<\/li>\n<li><strong>Other practical examples using Wien2K, KKR-CPA or Quantum Espresso:<\/strong>\n<ul>\n<li>Chalcogenide Perovskites; BaZrS3 for photovoltaic applications<\/li>\n<li>Alloying Chalcogenide Perovskites for Optimized Photovoltaic Application: BaZr1\u2212xTixS3<\/li>\n<li>Organic\/inorganic hybrid perovskite CH3NH3PbI3 to improve the solar-conversion efficiency of dye-sensitized solar cells<\/li>\n<li>Phosphorene as a promising anode material for different rechargeable Batteries<\/li>\n<li>Hydrogen storage in doubly substituted Mg based hydrides Mg5MH12 (M = B, Li) and Mg4BLiH12<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>Program<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-515 size-large\" src=\"http:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page-944x1024.png\" sizes=\"(max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page-944x1024.png 944w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page-276x300.png 276w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page-768x833.png 768w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page-250x271.png 250w, https:\/\/med-space.org\/irsec16\/wp-content\/uploads\/2016\/07\/workshop-page.png 1023w\" alt=\"workshop-page\" width=\"700\" height=\"759\" \/><\/p>\n<p><a href=\"https:\/\/yzaz.net\/registration-form-IRSEC.php\">Apply to participate<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Materials Modeling and Simulation Training Workshop Many essential materials properties can nowadays be generated and screened by their computed properties even before their synthesis, this allowed to explore candidates which are critical to many technologies such as photovoltaics, storage, sensors, biomaterials, electronics.
