The most common semiconductor materials are silicon and germanium. These materials are then doped to create an excess or lack of electrons. Semiconductor Uses. Computer chips, both for CPU and memory, are composed of semiconductor materials. ... Computer Architecture Study Guide.
Jul 17, 2016· Germanium, Ge (number 32), computer chips operate faster than silicon, Si (number 14), computer chips. So how might a gallium, Ga (number 31), chip compare with a germanium chip? A) A gallium chip would be even faster because the gallium is more metallic. B) A gallium chip would be slower because its electrons are more loosely held. C) Gallium is located just below aluminum, .

Dec 10, 2005· Silicongermanium amplifiers can only produce about one watt of radio frequency (RF) power, versus 10 watts from a typical gallium arsenide device. "While that's not adequate for some applications, it could be perfect for radar," said Mitchell, citing a GTRI study conducted for the Missile Defense Agency several years ago.
We also study if this substitution has an impact on optical gain; Therefore, we theoretically discuss the effect of substituting tensilestrained germanium with tensile strained silicongermanium alloy on the directgap optical gain, and the results are compared with each other.
