Boron-Doped Diamond

When your design needs diamond that conducts, boron changes its electrical behaviour.

Good to know

Doping level and resistivity are related but are not interchangeable specifications.
A doped plate is a material; an electrode also needs contacts and an exposed working surface.

What we define for boron-doped diamond, with units and how each is typically measured. We confirm values for your application in technical review.
