What is the Ab Initio Simulation Package (AIMS)?
The Ab Initio Simulation Package (AIMS) is a state-of-the-art computational tool designed for performing highly accurate simulations of materials at the atomic scale. This software utilizes first-principles or
ab initio methods, which rely on quantum mechanics to predict the properties and behaviors of materials without requiring empirical parameters.
Why is AIMS Important in Nanotechnology?
Nanotechnology focuses on manipulating materials at the nanoscale, where the properties of materials can differ significantly from their bulk counterparts. Precise understanding and control at this scale are crucial for developing new
