The research team from UCLA Samueli School of Engineering reported that metallic theta-phase tantalum nitride conducts heat ...

Using advanced techniques, researchers more-accurately characterized the thermal conductivity of four distinct GaN substrate types along with their defect density, and developed a formula linking the ...

Power density plays a critical role in making power electronic systems smaller, more efficient, and more cost-effective. As power density increases, so does the heat generated inside a device.

(a) The minimum, average and maximum temperature profile from the surface to the depth of 1 m with a surface pressure of 80 Pa. (b) The bulk density profile from the surface to the depth of 1 m ...

Power electronics are experiencing a continuous rise in their power densities. As a consequence, thermal management for today's power semiconductors must be integrated as early as their design phase.

Polymers are composed of very large molecules formed by a combination of different monomers (smaller and simpler molecules), which can be natural or synthetic. Polymers are the basis of many ...

Mini LED chips can measure as small as 50μm × 100μm, with pad spacing as narrow as 5-50μm, demanding extreme precision in ...

eGaN FETs and ICs enable very high-density power converter design, owing to their compact size, ultra-fast switching, and low on-resistance. The limiting factor for output power in most high-density ...
