Peer-reviewed findings support Diamond Quanta's engineered-diamond process platform and advancement toward tool-enabled development for future electronic, photonic, and quantum applications.

Diamond Quanta Inc., a semiconductor materials platform company developing manufacturable engineered-diamond infrastructure for electronic, photonic, thermal, and quantum applications, today announced that its article, “Sub-melt nanosecond pulsed-laser induced densification and strain-field relaxation in single-crystal diamond,” has been published in Carbon Trends. The findings address a longstanding challenge in diamond materials, where defects and strain fields can limit device performance and broader commercial adoption.

The peer-reviewed study reports that sub-melt nanosecond pulsed-laser processing can induce measurable densification and strain-field relaxation in single-crystal diamond without detectable graphitization. The work combines interferometry-derived surface metrology, Raman spectroscopy, and electron microscopy-based structural analysis to evaluate how diamond responds to controlled pulsed-laser exposure.

Importantly, the reported Raman response indicates linewidth recovery extending to device-relevant depths of approximately 2 to 3 microns. This suggests that the process affects strain-field relaxation beyond the nanometer-scale densification signature measured at the surface. That distinction is important for diamond technologies because dislocation-associated strain and defect networks can critically affect quantum, photonic, thermal, and microelectronic device performance. These findings are significant because defects and strain fields can limit the performance, reliability, and manufacturability of diamond-based devices. Understanding and controlling those effects is an important step toward broader adoption of diamond in future optical, semiconductor, photonic, and quantum systems.

“Diamond’s potential has always been extraordinary, but device adoption depends on solving the defect and strain-field problem at technologically relevant depths,” said Adam Khan, Founder and CEO of Diamond Quanta, and lead author on the study. “This publication provides peer-reviewed evidence that sub-melt nanosecond laser processing can densify and relax strain fields in single-crystal diamond without graphitization. For Diamond Quanta, it strengthens the scientific foundation for our engineered-diamond process platform and our next phase of tool-enabled development.”

“The study demonstrates how controlled laser processing can be used to interrogate and modify near-surface structural states in diamond while preserving the crystalline phase,” said co-author Ted Laurence, of Lawrence Livermore National Laboratory.

The publication is directly aligned with Diamond Quanta’s broader technology roadmap. Diamond Quanta is preparing for deployment of an alpha diamond-processing tool targeted for the end of summer. The system is expected to integrate a laser-processing module that embodies the same sub-melt processing concepts described in the Carbon Trends publication, moving the approach from peer-reviewed demonstration toward controlled, tool-enabled process development.

More broadly, the publication represents another milestone in Diamond Quanta's strategy of combining peer-reviewed scientific validation, proprietary process innovation, protected intellectual property, and manufacturing ecosystem development to accelerate commercialization of engineered-diamond technologies.

“Independent peer-reviewed validation plays an important role in reducing commercialization risk for emerging materials platforms," said Michael Pierantozzi, co-founder and COO of Diamond Quanta. "This publication strengthens the technical foundation underlying our Adamantine Platform™, supports our broader process-development roadmap as we advance toward tool-enabled development and OEM qualification activities.”
