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 ...

Hundreds of decommissioned manufacturing tools from Ubiquity Solar, including semiconductor and photovoltaic production lines ...

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 ...

The approach, termed ‘germanium on nothing’, could enable the cost effective, high volume production of PV cells based on III-V materials such as gallium arsenide. June 10, 2019 Mark Hutchins ...

GaN and GaAs are used for a variety of transistors, including bipolar junction (BJT), enhancement-mode MOSFET and high electron mobility (HEMT). See gallium nitride and gallium arsenide.

For example, US imports of gallium metal and gallium arsenide wafers in 2022 were valued at only about $225 million, according to government data. But their use in strategic industries means any ...

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 ...
