Gallium arsenide is a compound semiconductor which may be defined as a semiconductor made of a compound of two elements (as opposed to silicon which is a single element semiconductor) The figure below shows the arrangement of atoms in a gallium arsenide substrate material Note the alternate positioning of gallium and arsenic atoms in their
An important issue due to the recombination activity of extended defects in the silicon lattice are the dislocations We have investigated two different mc-Si materials which were intentionally doped with germanium in concentrations of 0 5 % to 2 % of weight An influence of the germanium on the distribution of oxygen carbon and the
Germanium is mainly a byproduct of zinc ore processing It is a hard grayish-white element it has a metallic luster and the same crystal structure as diamond and it is brittle like glass In addition it is important to note that germanium is a semiconductor with electrical properties between those of a metal and an insulator The development of the germanium transistor opened the door to
The radiation hardness of Czochralski grown n-type silicon samples doped with germanium (NGe = 21020 cm−3) and without it was investigated after irradiation by fast neutrons The dependence of the effective carrier concentration on fluence was described in the framework of Gossick's corrected model It was found that doping the germanium impurity resulted in increase of n-Si radiation

The team fabricated a 100-by-250-micrometer rectangle of germanium doped with phosphorous on a silicon surface They then drove a current in the long direction and sought to measure the SHE by detecting the accumulated spin density vs position across the short direction—spin-up electrons should accumulate at one edge and spin-down at the opposite edge The team produced a spin-density map

Silicon Planar Transistors The disadvantages of diffused alloy transistors was overcome in the 1950s by developing transistors that use silicon as the semiconductor material and the planar (layered) type of construction illustrated in Figures 3 2 2 to 3 2 3 These transistors are built up as a series of very thin layers (or planes) of semiconductor material built up rather like a multi layer

If you want to grow n-doped GaN layers on silicon with minimal tensile strain then consider using germanium rather than silicon as the n-type dopant That's the key finding of a study by researchers from the Otto-von-Guericke-University Magdeburg Germany that have compared the tensile strain of GaN layers doped with both of these group IV elements
Germanium is a metalloid A metalloid is an element that has characteristics of both metals and non-metals Germanium is located in the middle of the carbon family which is Group 14 (IVA) in the periodic table The periodic table is a chart that shows how chemical elements are related to each other Carbon and silicon are above germanium and tin and lead are below it The existence of
