More Than a Supplier

GLCT takes diamond programs from crystal growth through post-processing, packaged, and production-ready implementation

Beyond the catalog

From early material development to a packaged, production-ready part — we support your program end to end, so your team isn’t stitching together five vendors.

  • Controlled ¹²C Isotopic Enrichment — Isotopically engineered material for programs where thermal transport and phonon behavior can’t be left to natural isotopic variation.
  • Controlled NV Center Post-Processing — Nitrogen-vacancy density and charge-state tuned to your application, not left to as-grown variability — built for quantum sensing and magnetometry payloads.
  • Extended Wafer Surface Preparation — Surface finishing beyond catalog polish specs, engineered for demanding bonding, interface, or optical requirements.
  • Extended Wafer Geometry Preparation — Non-standard geometries and tolerances, so your design isn’t constrained by a standard part number.

What We’re Building Toward

We invest ahead of where our partners’ programs are headed.

  • Boron-Doped Epiwafer & Bulk Diamond — Opening the door to conductive and semiconducting diamond for power electronics programs.
  • Uncommon Crystallographic Orientations — Development work on non-standard cut faces for programs whose requirements fall outside standard-cut material.
  • Diamond Circuit Board Preparation — Early-stage work pairing diamond’s thermal performance directly with the electronics it protects.

Philosophy For Advancement

Advancing What’s Next — On Earth and In Space

Building the materials behind the next era of computing, sensing, and energy, from data centers to spacecraft.

Do It Collaboratively. 
Do It Right.

Every partner and every project is a long-term relationship. We work alongside your team from concept through implementation.

No Black Boxes

Investors, program leaders, and technical teams get the same thing from us: clear status, active communications, and access to the team doing the work.
