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.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
