Abstract Details

2023, Master of Science, Miami University, Mechanical and Manufacturing Engineering.
Silver sulfide has garnered significant interest across a range of applications, such as resistive-switching, atomic switches, and neuromorphic systems, due to its exceptional superionic properties and memristive characteristics. An inherent challenge in atomic switches is the loss of accuracy over time, attributed to the accumulation of disorder within the silver sulfide crystal used in these switches. During the RESET and SET operations of the atomic switch, only a portion of the Silver Sulfide undergoes a transformation, resulting in a metaphase state of the atomic switch crystal. This constraint restricts the lifespan and reliability of the atomic switch. To address this, the present study employs MD simulation to investigate the local structural topology of polycrystalline silver sulfide. A numerical method was developed to quantitatively measure Relative Electrical Conductivity by examining the metaphase state of the silver sulfide atomic switch at a molecular level; this research aims to enhance our fundamental understanding of its behavior which can contribute to the development of improved atomic switch designs, and performance enhancements. In addition, it will be demonstrated in this study how the application of graph theory-based descriptors can link the structural characteristics of polycrystalline silver sulfide to their electrical properties.
