The development of high-performance octadecyltrichlorosilane (OTS) SAMs is crucial for mitigating alkali-metal spin relaxation and enhancing the sensitivity of spin-exchange relaxation-free (SERF) magnetometers. In this work, we employ molecular dynamics (MD) simulations to investigate the structural, interfacial, and dynamical properties of OTS SAMs, focusing on optimizing their anti-relaxation behavior. By systematically tuning key simulation parameters, including adsorption energy, wettability, and atomic interaction dynamics. Our findings provide a comprehensive framework for the rational design and optimization of OTS SAMs, paving the way for next-generation atomic magnetometers with enhanced stability and prolonged coherence times. Furthermore, we discuss the broader implications of these advancements in quantum sensing and precision measurement applications.
