Case Study: sp² Carbon Allotropes
The LEGO-xtal framework was applied to sp² carbon allotropes, starting from only 25 known low-energy structures. It successfully generated over 1,700 new structures, including large unit cells (up to 960 atoms) and diverse topologies, all within 0.5 eV/atom of graphite's ground-state energy. This demonstrates its capability to explore complex material spaces efficiently.
Key Takeaway: The framework's ability to generate a multitude of thermodynamically stable and novel carbon allotropes from a small initial dataset validates its potential for targeted material design beyond conventional methods.

Implementation Roadmap
A typical phased approach for integrating AI-assisted material generation into your R&D workflow.
Phase 1: Data Integration & Augmentation
Collect and augment existing crystal structure data, leveraging subgroup symmetries to enrich the training dataset for generative models.
Phase 2: AI Model Training & Generation
Train VAE/GAN models on the augmented data to learn statistical distributions, then sample new crystal structures.
Phase 3: Structure Pre-Relaxation & Validation
Apply descriptor-guided optimization (SO(3) descriptor) to refine generated structures to target local environments, followed by physical model validation (ReaxFF/MACE).
Phase 4: Novel Structure Identification & Analysis
Identify unique, low-energy, and stable structures, characterizing their topology and properties to uncover novel material candidates.
