AI for Semiconductor and Electronic Materials

Accelerate the discovery and optimization of semiconductors, dielectrics and optoelectronic materials with physics-grounded artificial intelligence and high-throughput simulation.

We develop project-specific workflows that connect curated experimental and computed data with density functional theory, atomistic calculations and uncertainty-aware machine learning. The result is a traceable shortlist of candidates, defects, dopants or process conditions ready for targeted computational or experimental validation.

Integrated approach

AI constrained by electronic-structure physics

Reliable predictions require consistent structures, appropriate theory levels and an explicit view of where a model is interpolating or extrapolating.

✓

Structure and data curation

Standardize crystal structures, compositions, polymorphs, units, calculation settings, measurement conditions and provenance.

✓

Fit-for-purpose electronic structure

Select semilocal, meta-GGA, hybrid-functional, GW or spin-orbit-aware calculations according to the endpoint and required fidelity.

✓

Hybrid prediction and optimization

Combine graph models, interpretable descriptors, DFT-derived features and Bayesian optimization under stability and synthesis constraints.

✓

Applicability and uncertainty analysis

Report calibrated intervals, domain distance, model disagreement and validation priorities instead of unsupported point estimates.

FAQ

Frequently asked questions

Can you predict semiconductor band gaps accurately?

Band-gap accuracy depends strongly on the material and theory level. Semilocal DFT is useful for trends but often underestimates gaps; we can use calibrated models, hybrid functionals or higher-level methods when the project requires them, and we report assumptions and uncertainty.

How are charged defects and dopants treated?

Projects may include supercell convergence, electrostatic finite-size corrections, potential alignment, competing-phase chemical potentials, multiple charge states and Fermi-level-dependent formation energies. The exact protocol is documented in the deliverables.

Can you work with a small proprietary dataset?

Yes, after a feasibility audit. Physically meaningful representations, transfer learning, Gaussian processes, targeted simulation and active learning may be appropriate. If evidence is insufficient, we define the minimum additional calculations or measurements needed.

Do screening results guarantee synthesis or device performance?

No. Screening reduces the design space and prioritizes validation; it does not replace synthesis, processing or device testing. We distinguish computed stability from kinetic accessibility and provide validation recommendations matched to the highest-risk assumptions.
