The aim of the course is to introduce and practice the basic simulation approaches currently applicable to atomistic simulations of structure, energy, static and dynamic properties of quantum nanostructures. The course is realized by a combination of theoretical lectures and practical exercises conducted in the KIPL computer classroom within the Materials Studio simulation tool. The knowledge of solids theory and the basics of computer simulations of condensed matter in the extend of master courses at FJFI is assumed. The graduate will acquire the theoretical basis and practical skills needed to implement his own atomistic simulations of quantum structures.

Syllabus of lectures:

1.Construction of low-dimensional structures (2D, 1D, 0D structures; Use of fragment libraries; Periodic boundary conditions)2.Geometric optimization (MD / MC methods; DFT approach –Onetep, Castep, Vasp)3.DFTB+ method (Theory; Slater-Koster libraries, creating / adapting for given model)4.Application of DFTB+ method (Optimization of carbon nanotubes; Electron transport between electrodes using non-equillibrium Green’s function formalism; Calculation of U / I curves, transmission function and electron potential)5.Kinetic Monte Carlo method (Principles; Simulation of surface chemical reaction; Implementation in Kinetix module; Example: CO oxidation on Pt (111) surface)6.Reaction kinetics: Transition state search (Linear response method, principles, numeric base functions and augmented plane waves implementations –DMol3, Turbomole, Gaussian, Castep, Onetep)7.Combined QM / MM calculations (Model design; Setting up calculation in QMera; Analyzing electronic orbitals and contributions to the total energy; Application to organometallic complexes)
