Boron-Doped Diamond

  • [The Ultimate Material for Next-Generation Semiconductors and Extreme Electrochemistry] Utilizing an advanced boron-doped process, insulating diamond is perfectly transformed into a highly conductive P-type semiconductor.
    With an extremely wide electrochemical operating window and unparalleled corrosion resistance, it is a key component for high-power device heat dissipation, challenging industrial wastewater treatment (AOPs), and highly sensitive electrochemical sensing.

    • Ultra-high stability: Resistant to strong acids and alkalis, high temperature and high pressure, zero metal ion release.

    • Extremely wide working window: Hydroxyl radical (·OH) generation efficiency is the highest among all electrodes.

    • Ultimate Thermal Management: Ultra-high thermal conductivity, breaking through the heat dissipation bottleneck of high-power chips.

Boron-Doped Diamond

Boron-Doped Diamond Electrode (BDDE) / Single crystal boron-doped diamond substrate

Honway Materials provide customized services,

We will create the most suitable boron-containing diamond substrate for you.

 

Features:

  • The wide electrochemical working window has extremely high hydrogen evolution and oxygen evolution overpotentials in aqueous solution, and can withstand extremely high voltages without hydrolysis, exhibiting a strong oxidation capability that other traditional metal electrodes (such as platinum and iridium oxide) cannot match.

  • Exceptional physical and chemical stability (Extreme Stability) Inherited from diamond’s extremely high hardness and corrosion resistance. When facing extreme and harsh environments such as strong acids, strong alkalis, and strong oxidants, the electrode body suffers near-zero wear, has an extremely long service life, and does not produce secondary pollution.

  • The ultra-low background current and high sensitivity, along with extremely low surface capacitance, significantly reduce noise interference during electrochemical detection, greatly improving the sensitivity and accuracy of microanalysis and biomedical sensing.

  • When used as a substrate, it offers superior thermal conductivity, providing thermal efficiency several times higher than copper, making it the ultimate heat sink solution for third- and fourth-generation semiconductor (GaN/SiC) devices.

Application areas:

  • 1. Industrial wastewater and high-difficulty water treatment

    • Advanced oxidation processes (AOPs): Effectively degrade high-concentration COD and highly toxic, recalcitrant organic wastewater from coking, pharmaceutical, and chemical plants.

    • Chemical-free disinfection: Electrolysis of water can directly and efficiently generate ozone or active oxygen, suitable for high-tech water purification, medical sterilization, and swimming pool disinfection.

    2. Semiconductors and high-power electronic components

    • High-power chip heat sink substrate: Used in GaN-on-Diamond or SiC-on-Diamond architectures to solve the heat dissipation bottleneck of 5G/6G base stations, radar, and electric vehicle inverters.

    • Extreme Environment Electronic Components: Utilizing their radiation resistance and high temperature resistance, high-frequency and high-voltage components are developed for space or deep well exploration.

    3. Precision Electrochemical Sensing

    • Environmental monitoring: Real-time quantitative analysis of trace heavy metals (lead, cadmium, mercury) and pesticide residues in water.

    • Biomedical sensors: Sensitive detection of neurotransmitters (such as dopamine) or specific biochemical indicators in the human body.
