Researchers at the University of Glasgow have made a milestone in developing a new generation of diamond transistors that will break through technical limitations and move closer to practical applications in high-power industries.
The research team has discovered a new method to make transistors out of diamond, which can be turned off by default and improve device safety. Diamond can withstand voltages much higher than silicon due to its wide bandgap properties, making it suitable for high-power applications. The transistor can be used in high-voltage, high-efficiency fields such as power grids and electric vehicles.
Professor David Moran's team at the University of Glasgow collaborated with universities in Australia and the United States, and the research results were published in Advanced Electronic Materials. Professor Moran pointed out that power electronic devices require high-power switches, but diamond transistors often lose sight of one thing while focusing on the other. His team successfully designed a diamond transistor that performs well in both shutdown and power supply functions, making significant progress.
The research team at the University of Glasgow used surface chemistry technology to improve the performance of diamond, first coating it with hydrogen atoms and then with aluminum oxide. The new diamond transistor requires 6 volts to turn on, has a large current, and doubles the efficiency of charge movement. When turned off, the resistance is extremely high, there is almost no current leakage, and the safety performance is improved. Professor Moran said that this result is encouraging, and diamond transistors have great potential and low cost, but there are still challenges to overcome, hoping to promote future applications.
High Light Intelligence Technology, a pioneer in the CVD diamond industry, has advanced MPCVD technology and CVD diamond production workshops. We focus on producing high-purity lab-grown diamonds for the jewelry industry, and at the same time create industrial-grade CVD diamond products, covering single crystals, polycrystalline, films and diamond surface metallization. We also provide 6kw/10kw/15kw MPCVD equipment to help customers in all aspects, from equipment to products, and then to all-round services, to create brilliance together.

Single-Crystal vs Polycrystalline CVD Diamond: Process Difference Lies in Growth Logic, Not Equipment
The process difference between single crystal and polycrystalline CVD diamond lies not in equipment, but in growth logic. Single crystal and polycrystalline CVD diamond are two functional new materials with completely independent growth mechanisms, lattice structures and performance systems. Their process logic, product features and application boundaries diverge fundamentally from the very start of deposition and growth. Comparing or selecting materials without considering their underlying crys

From Lab-Grown Diamonds to Industrial Diamonds: Is It Time to Build an MPCVD Factory?
The lab-grown diamond industry is entering a new stage. Over the these few years, lab-grown diamonds have gradually gained wider acceptance in the jewelry market. With the development of production technology, equipment maturity and supply chain improvement, the industry is becoming more standardized and efficient. But beyond jewelry, another opportunity is attracting more attention:Industrial diamond applications.

Diamond‑Copper Composite: A Next‑Generation Solution for High‑Power Electronics Thermal Management
Diamond‑copper composite (DC) is an advanced metal‑matrix composite material consisting of diamond particles as the reinforcement phase and copper as the matrix, fabricated through state‑of‑the‑art composite preparation techniques. Diamond has the highest thermal conductivity of any naturally occurring material, with isotropic values ranging from 1200 to 2300 W/m·K. Copper, with a thermal conductivity of 401 W/m·K, ranks second only to silver among common metals. By combining the two, the compo

Mosaic Single‑Crystal Diamond: Breaking Size Limits
With an ultra‑wide bandgap of 5.47 eV, ultra‑high thermal conductivity (>2000 W/m·K), high carrier mobility (electron mobility up to 4500 cm²·V⁻¹·s⁻¹), and ultra‑high theoretical breakdown field strength (>10 MV/cm), Single‑Crystal Diamond (SCD) is an ideal candidate for next‑generation high‑power, high‑frequency and extreme‑environment electronic devices. However, both natural diamond and HPHT‑synthesized single‑crystal diamond are limited in lateral size, which greatly hinders large‑scal
