Tantalum Oxide Sputtering Targets and Applications

Tantalum oxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta2O5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Tantalum Oxide (Ta2O5) Sputtering Targets (Size:2'' ,Thickness:0.125'' , Purity: 99.99%) is an inert material with a high refractive index and low absorption which makes it useful for coatings. It is also extensively used in the production of capacitors, due to its high dielectric constant.
Tantalum oxide films are of interest for applications in high temperature resistance, anti-reflection coatings for solar cells, optical waveguide, oxygen sensors, and capacitor dielectric materials. In recent years they have received increasing attention as an alternative dielectric to replace thin SiO, films for storage capacitors in very large-scale-integrated memory cells and as gate insulators in metal-oxide-semiconductor devices.
Tantalum oxide films can be formed by at least five different methods: (1) thermal oxidation of sputtered tantalum films; (2) chemical vapor deposition (CVD) using a TaCl, (3) anodization of Ta metal films (4) magnetron sputter deposition from a Ta,O2 target ; (5) reactive sputtering of a pure Ta target using O2-Ar gas .
Also tantalum oxide sputtering targets can be used for high dielectric constant materials because of its high dielectric constant, high refractive index and chemical and thermal stability with the promise of compatibility in the microelectronics processing.

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 that i

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.
