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.

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 ...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
