TU Dortmund physicist Alex Greilich and his team created a crystal of indium gallium arsenide doped with silicon (a.k.a. a semiconductor). In this crystal, the nuclear spins “act as a reservoir ...

Norwegian scientists have developed a gallium arsenide (GaAs ... a technique commonly used for thin-film deposition of single crystals in the production of semiconductor devices.

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 ...

and indium gallium arsenide antimony nitride and use photonic crystal film for maximum efficiency. Scientists from Tufts University have developed light-tracking solar cells based on a novel ...

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.

As great as silicon is for semiconductor applications, it has one weakness in that using it for lasers isn’t very practical. Never say never though, as it turns out that you can now grow ...

T oday, silicon photonic circuits connect server racks and play key roles in chemical sensors, biosensors, and LIDAR for self ...

Colloidal solutions of gallium arsenide quantum dots of the type used in lasers, TVs, solar cells, medical devices, and other electronics glow under UV light. These were grown using a ...
