G-ray’s near-term focus is on a germanium-rich silicon alloy, which reduces the need for cooling by increasing the resistance compared with pure germanium, but the company now has the scope to ...

But just as it had taken years to produce pure enough germanium, it took several years to produce pure enough silicon. By the time he succeeded, Teal was working at Texas Instruments. Luring ...

Takashi Yagi from the National Institute of Advanced Industrial Science and Technology, Japan, investigated the multivalley optical switching phenomenon in germanium (Ge) films. They focused on ...
