Examples of substitutional isoelectronic atoms for a group IV material such as Si would be any other element in the column: C, Ge, and Sn may each substitute for Si without influencing the number of valence electrons. They are electrically inactive in the sense that they do not influence the...

The characteristics of silicon in some ways resemble those of the element germanium,which is located just below it in the carbon group. Flint is the noncrystalline form of silicon and has been known to humans since prehistorictimes. When struck with a sharp blow, flint would flake off sharp-...

The most common interpretation of these properties is in terms of electrical conductivity, where semi-metals can perform as metals (conductors) under certain conditions only. Semi-metals like silicon and germanium are important semiconductors.Answer and Explanation: ...
(SiGe) alloys have attracted a lot of interest in semiconductor research because of their special structure and beneficial physical characteristics. SiGe alloys are preferable to their elemental equivalents because they can have adjustable properties due to their combination of germanium (Ge) and silicon...
To overcome these constraints from silicon perform- ances limitation, major semiconductor companies have understood that it has become necessary to make use of new compound materials like silicon germanium (SiGe) and gallium arsenide (GaAs). For some applications it is even better to turn to ...
The formation of nonequilibrium phases during unloading from metallic Ge-II has been confirmed by means of Raman spectroscopy [107–109]. Due to similarities in the crystal structure of silicon and germanium, most features inherent to the Raman spectra of various polymorphs of Si are present in ...
Hybrid laser on Si is another approach where integration of III-V semiconductor or germanium gain medium is done with a silicon platform for lasing. Here a Si waveguide is fused to an active light-emitting, III-V epitaxial semiconductor wafer designed with different layers such that the active ...
Silicon photonics has developed into a mainstream technology driven by advances in optical communications. The current generation has led to a proliferation of integrated photonic devices from thousands to millions-mainly in the form of communication tra
