Consequently, a gallium arsenide wafer, or substrate, is semi-insulating, whereas a silicon wafer is semi-conducting. Gallium arsenide also offers a wider range of operating temperatures than silicon ...

Researchers at Imec have found a way to grow lasers directly on silicon Imec’s lasers use gallium arsenide ... They begin by ...

The most optimal material for solid-state lasers in photonics is gallium-arsenide (GaAs), but due ... grown on industry-standard 300 mm silicon wafers. The trick was to accept the lattice mismatch ...

In 2001, Motorola developed a technique that places a spongy layer between gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost.

A breakthrough in next-generation semiconductor technology has been announced by Chinese researchers, with the creation of the world’s largest N-polar gallium nitride (GaN) wafer, at eight ...

material which could improve the efficiency of multi-junction solar cells based on III-V elements such as gallium arsenide. In the paper Uprooting defects to enable high-performance III–V ...

The researchers built the device with an electron-blocking layer made of aluminium gallium arsenide phosphide (AlGaAsP), instead of more commonly used gallium indium phosphide (GaInP), that was ...
