CVD diamond with controlled boron doping — from semi-insulating to metallic conductivity. The widest electrochemical window of any electrode material (3.5V). Used in neural implants, environmental sensors, power transistors, and superconducting quantum devices.
All doping levels available to order. Specify [B] concentration or target resistivity when requesting a quote.
| Grade | [B] Concentration | Resistivity | Primary Applications |
|---|---|---|---|
| Light | 10¹⁶ – 10¹⁷ cm⁻³ | 10² – 10⁴ Ω·cm | Quantum device substrates, UV detectors |
| Moderate | 10¹⁷ – 10¹⁹ cm⁻³ | 10⁻¹ – 10² Ω·cm | Biosensors, neural interfaces, power transistors |
| Heavy | 10¹⁹ – 10²⁰ cm⁻³ | 10⁻³ – 10⁻¹ Ω·cm | Electrochemical electrodes, water treatment |
| Metallic | >10²⁰ cm⁻³ | <10⁻³ Ω·cm | Superconducting devices, ohmic contacts |
Boron doping is characterization-intensive. Every BDD piece ships with the data your device team needs to integrate it with confidence.
