Germanium Sputtering Targets and Applications

Germanium is a chemical element with the symbol Ge and atomic number 32. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.
Germanium sputtering targets can be used in transistors and electronic devices as a semiconductor. Nowadays, germanium is used in fibre-optic systems, infrared optics, solar cell applications, and light-emitting diodes (LEDs).
Compounds made of germanium are also used in polymerization reactions as catalysts. Also in nanowires germanium compounds are used. In organometallic chemistry the element forms a large number of organometallic compounds, such as tetraethylgermane, are useful.
Germanium sputtering target has a similar structure to silicon, however, when we compare these two elements germanium offers several benefits like faster carrier mobility, smaller band gap and lower process temperatures. Also, the germanium has larger Bohr radius than silicon and this property allows for quantum effects to appear in nanostructures exhibiting larger sizes. Germanium is compatible with complementary metal oxide semiconductor technology and the production of porous germanium thin films could be used for integration of optoelectronic devices in silicon microelectronic technology.
Porous germanium thin films can be obtained by different techniques like anodization and electrochemical etching, spark processing or inductively coupled plasma chemical vapor deposition.

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...
