The discussion covers how a French consortium involving DIAMFAB, STMicroelectronics, and CEA came together around tritium-based betavoltaic technology, why commercialization still requires careful regulation and scaling, and why technology-grade grown diamond may be one of the most important semiconductor materials for the future.

Diamond’s ultra-wide bandgap, radiation hardness, low atomic number, and improved commercial availability make it a powerful candidate for next-generation energy conversion. The episode also looks ahead to future work involving ESA and Orano, with potential space applications and nuclear-waste revalorization on the horizon.

In Part 1 of our interview with David Roy-Guay, we explore how SBQuantum is using diamond-based quantum magnetometry to measure Earth’s magnetic field with remarkable precision.

SBQuantum’s technology recently launched aboard a SpaceX rocket as part of a mission connected to magnetic-field mapping ... but the implications go far beyond space.

This conversation explores:
✅ How technology-grade grown diamond enables quantum sensing
✅ Why diamond magnetometers are so valuable in harsh environments

✅ The role of NV centers and vector magnetic-field readings

✅ Future applications in navigation, mining, defense, security, and chip inspection

✅ Why the diamond supply chain matters for next-generation quantum devices

Diamond is becoming a platform for advanced technology ... and quantum sensing may be one of its most exciting frontiers yet.

Dr. Bruckmaier explains how engineered nitrogen-vacancy centers, or NV centers, inside ultra-pure lab-grown diamond can detect magnetic fields produced by computer chips, helping manufacturers locate hidden defects, analyze failures, and improve chip reliability without destructive testing.

The conversation explores why diamond’s intentional atomic “imperfections” are so valuable, how room-temperature quantum sensing gives diamond a practical advantage over cryogenic platforms, and why this technology matters as the semiconductor industry moves toward more complex stacked chip architectures.

The episode also looks ahead to the future of failure analysis, inline metrology, advanced packaging, supply-chain resilience, and the broader role of Technology-Grade Grown Diamond (TGGD) in quantum sensing, thermal management, high-power electronics, navigation, biomedical applications, and next-generation manufacturing.
