![]() Atomic-scale simulations make it possible to guide experimental investigations towards the most promising part of the technology design space. ![]() Wise memory optimizer 3.65 review trial#The early research stage often has a very large design space, and experimental trial and error is a linear process that will explore only a small part of this space. The current main application of atomic-scale modelling is in early-stage research into new materials and technology designs, see for examples. With development of increasingly advanced simulation algorithms and more powerful computers, we expect that the economic benefits of atomic-scale modelling will only increase. Surveys indicate that the return on investment of atomic-scale modelling is typically around 5:1. These are calculations of the phonon-limited mobility of Cu, Ag and Au, electron transport in a gated 2D device, multi-model simulation of lithium ion drift through a battery cathode in an external electric field, and electronic-structure calculations of the composition-dependent band gap of SiGe alloys.Ītomic-scale modelling is increasingly important for industrial and academic research and development in a wide range of technology areas, including semiconductors, batteries, catalysis, renewable energy, advanced materials, next-generation pharmaceuticals, and many others. Besides giving a general overview and presenting a number of implementation details not previously published, we also present four different application examples. Seamless integration of the different simulation engines into a common platform allows for easy combination of different simulation methods into complex workflows. The platform includes a long list of advanced modules, including Green's-function methods for electron transport simulations and surface calculations, first-principles electron-phonon and electron-photon couplings, simulation of atomic-scale heat transport, ion dynamics, spintronics, optical properties of materials, static polarization, and more. Density functional theory is implemented using either a plane-wave basis or expansion of electronic states in a linear combination of atomic orbitals. ![]() The QuantumATK simulation engines enable electronic-structure calculations using density functional theory or tight-binding model Hamiltonians, and also offers bonded or reactive empirical force fields in many different parametrizations. ![]() While different aspects and individual modules of the platform have been previously presented, the purpose of this paper is to give a general overview of the platform. Wise memory optimizer 3.65 review software#QuantumATK is an integrated set of atomic-scale modelling tools developed since 2003 by professional software engineers in collaboration with academic researchers. ![]()
