Since the early 1970s, scientists have been promoting gallium arsenide as a faster, more efficient substrate material than silicon for making integrated-circuit chips. However, the vast majority of ...

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.

The most optimal material for solid-state lasers in photonics is gallium-arsenide (GaAs), but due to the misalignment of the crystal lattice between the compound (group III-V) semiconductor and ...
