Scientists from Novgorod State University (NovSU) have developed a technology for laser processing of silicon carbide and presented ultra-durable microdevices capable of operating stably where ordinary electronics melt or break down.
Silicon carbide is called a "semiconductor diamond" for its exceptional resistance to temperatures, radiation, and chemically aggressive environments. But as soon as the material heats up above a certain threshold, it does not melt, but immediately evaporates, which makes it extremely difficult to process.
The new method removes this limitation: researchers have found a way to "cut" and form surfaces using a laser in various environments — from air and water to oils and liquid nitrogen.
The main achievement is that the devices are completely monolithic: without assembly, without nodes and weak points. This makes it possible to significantly reduce the sensors and increases their durability, making them suitable for aviation, energy, oil and gas industry and any areas where equipment faces fire, high temperatures and aggressive environments.
