Introduction
Silicon carbide (SiC) is a widely used material in various applications due to its exceptional mechanical, thermal, and electronic properties. Chemical vapor deposition (CVD) is a key method for synthesizing SiC materials with precise control over composition, structure, and morphology [1]. Understanding the atomistic processes involved in the CVD of SiC is crucial for optimizing synthesis conditions and tailoring material properties. In recent years, ReaxFF molecular dynamics (MD) simulations have emerged as a powerful tool for gaining atomistic insights into complex chemical reactions occurring during CVD processes. This article explores the atomistic understanding of SiC material synthesis via ReaxFF-MD simulation of CVD, highlighting its applications, advantages, and challenges [2,3]. Silicon carbide (SiC) is a crucial material with a wide range of applications in electronics, aerospace, and renewable energy. Its unique combination of mechanical, thermal, and electrical properties makes it highly desirable for high-performance devices and structural components [4,5]. Chemical vapor deposition (CVD) is a dominant technique for synthesizing SiC materials due to its ability to precisely control composition, structure, and properties [6]. Understanding the atomistic processes underlying SiC material synthesis is essential for optimizing CVD processes and tailoring material properties to specific applications. ReaxFF molecular dynamics (MD) simulation has emerged as a powerful tool for gaining atomistic insights into complex chemical reactions occurring during CVD processes [7,8]. By simulating the interactions between gas-phase precursors, surface species, and substrate atoms at the atomic level, ReaxFF-MD simulations provide detailed information on reaction mechanisms, kinetics, and structure-property relationships. we explore the atomistic understanding of SiC material synthesis via ReaxFF-MD simulation of CVD [9]. We discuss the principles of ReaxFF-MD simulation, its applications in SiC CVD, and the insights it provides into reaction pathways, surface adsorption, and film growth mechanisms. Additionally, we highlight the advantages of ReaxFF-MD simulation, including its ability to simulate large system sizes and long time scales efficiently. Finally, we discuss the challenges and future directions of ReaxFF-MD simulation in advancing our understanding of SiC material synthesis and optimizing CVD processes for various applications [10].
Principles of reaxff-md simulation
ReaxFF is a reactive force field that enables the simulation of chemical reactions in molecular dynamics simulations. Unlike traditional force fields, ReaxFF parameters are derived from quantum mechanical calculations and can capture bond breaking and formation, making it well-suited for studying reactive systems such as CVD processes. In ReaxFF-MD simulations of CVD, the interactions between gas-phase precursors, surface species, and substrate atoms are modeled at the atomic level, providing detailed insights into reaction mechanisms and kinetics.
