Nonlinear photonics in silicon germanium waveguides

However the lattice mismatch between germanium and silicon eventually leads to a large density of threading dislocations at the germanium/silicon interface which limits the performance of nonlinear optical devices Our solution to this issue has been to use a silicon germanium-on-silicon platform with 40% of germanium in the alloy Silicon germanium waveguides buried in silicon which were

What is a Silicon Transistor? (with pictures)

A silicon transistor is a semiconductor made with a silicon base It is used in a wide variety of electronic devices such as televisions and phones to alter the flow of electrical current Silicon has largely replaced germanium in transistors because of its ability to continue operating at high temperatures The silicon transistor has other advantages over alternative materials such as

A horizontal germanium silicon heterostructure photodetector comprising a horizontal germanium pin diode disposed over a horizontal parasitic silicon pin diode uses silicon contacts for electrically coupling to the germanium pin through the p-type Categories Law Published Jun 9 2019

Silicon germanium (SiGe) is now a popular semiconductor that has skyrocketed in its production since the 90s But this semiconductor didn't rise to success overnight In fact the combination of silicon and germanium was discovered by accident The Inadvertent Discovery of SiGe In the 1970s and 1980s IBM researcher Dr Bernard Meyerson accidentally dropped a small piece of silicon he had

Silicon is also a relative abundant element on Earth though in nature silicon is often combined with other molecules such as oxygen (i e silica or sand) so man-made processing is needed to purify silicon However there are other materials that are commonly also used in the electronics industry such as germanium gold copper aluminum magnesium nickel cadmium and so on

Modeling of the germanium‐silicon data set using a 10 box model presented suggests that the only type of fractionation to adequately describe the observed data result from a subtle difference during uptake via a Michaelis‐Menten process This implies biological control over the uptake and therefore cycling of germanium and silicon in the ocean
