Computational Materials Science: An Introduction

Have you ever wondered how scientists study and design new materials without physically testing them in a laboratory? Computational Materials Science is a field that utilizes computer simulations to explore the properties and behavior of materials at the atomic and molecular level. By harnessing the power of computer algorithms and mathematical models, researchers can predict and understand the properties of materials, paving the way for innovative discoveries and advancements in various industries.

The Power of Simulations

Computational Materials Science allows scientists to perform virtual experiments on a wide range of materials under different conditions, ultimately saving time, money, and resources. Simulations offer a holistic view of materials, enabling researchers to investigate their structural, mechanical, electrical, and chemical properties without resorting to expensive and time-consuming physical experiments.

Simulations also allow scientists to study materials at different length scales, from atoms to bulk systems. They can observe how individual atoms interact with each other and how these interactions influence the overall behavior and functionality of the material. This deep understanding of atomic-scale phenomena aids in the development of materials with tailored properties and functionalities.

The Role of Quantum Mechanics

Quantum mechanics plays a fundamental role in Computational Materials Science. At the atomic and molecular level, materials exhibit quantum mechanical behavior, where electrons, for example, are described by wave functions. By solving complex mathematical equations based on quantum mechanics, researchers can predict the electronic and optical properties of materials. This knowledge is vital in developing materials for applications such as electronics, photonics, and renewable energy sources.

Computational methods, such as Density Functional Theory (DFT),allow scientists to simulate the behavior of electrons and predict how they will respond to external stimuli. These simulations provide insights into a material's electronic structure, bandgap, energy levels, and reactivity. Furthermore, Monte Carlo simulations and molecular dynamics simulations enable researchers to study the movement and behavior of atoms and molecules within a material, helping to understand processes like diffusion, phase transitions, and chemical reactions.

Applications of Computational Materials Science

The impact of Computational Materials Science extends across various fields and industries. In the field of energy, researchers employ simulations to enhance the efficiency and performance of energy storage systems, such as batteries and fuel cells. By understanding the intricate processes occurring at the atomic level, new materials can be developed that have greater energy storage capacities or faster charging times.

Computational Materials Science: An covers the essentials of computational science and explains how computational tools and techniques work to help solve materials science problems. The book focuses on two levels of a materials system: the electronic structure level of nuclei and electrons and the atomistic/molecular level. It presents computational treatments of these system levels using molecular dynamics (MD) and first-principles methods, since they are most relevant in materials science and engineering.

After a general overview of computational science, the text introduces MD methods based on classical mechanics and covers their implementation with run examples of XMD and LAMMPS. The author discusses first-principles methods based on quantum mechanics at an introductory level, using illustrations and analogies to assist students in understanding this difficult subject. The book then describes the density functional theory (DFT)—the first-principles method that can handle materials practically. It also reveals how each orbital of electron leads to particular properties of solids, such as total energy, band structure, and barrier energy. The final chapter implements the DFT into actual calculations with various run examples via the VASP program.

Computational methods are contributing more than ever to the development of advanced materials and new applications. For students and newcomers to computational science, this text shows how computational science can be used as a tool for solving materials problems. Further reading sections provide students with more advanced references.
