White meals are an important category of metals used in various industrial applications, just as alloys are. An old use of white metals is their referencing in the antique trade for describing items suspected of containing silver but not hallmarked. As an example, the term “white metal” is used in the British fine art trade...Continue Reading
The third generation of semiconductor materials are those materials with a wide bandgap (Eg≥2.3eV). They usually have high breakdown electric field, high thermal conductivity, high electron saturation rate and higher radiation resistance. That is why they are used for making high temperature, high frequency, radiation-resistant and high power devices. Typical materials are silicon carbide (SiC), gallium nitride (GaN),...Continue Reading
One of the most widely used transparent conducting oxides is indium tin oxide (ITO) — and for very good reasons. Indium tin oxide is well known for its electrical conductivity, optical transparency, and how easy it is to deposit as a thin film. In most cases, thin films of ITO are deposited on surfaces by...Continue Reading
New technology is coming out everyday, becoming more efficient and advanced each second. Technology makes life easier by having the internet at the tip of your fingertips in a matter of seconds. New apps are created daily to help us with everyday tasks like grocery shopping or calculating your tip at a restaurant. With all...Continue Reading
Optical coatings are widely used to change the reflectivity of the lens surface, from glasses to high-power laser applications. The core technology of femtosecond laser coating is that its coating has the characteristics of low dispersion and high damage threshold. This article talks about three commonly used sputter coating techniques, and introduces the physical principles...Continue Reading
As for the two most commonly used metals for engagement and wedding rings, platinum and gold, most people distinguish them by their different colors-platinum is naturally white, and gold is naturally yellow. However, rings made of white gold (composed of gold, alloys, and a rhodium plating) have a similar white color to platinum rings. Since...Continue Reading
Sputtering targets have important applications in many areas, such as architecture, optics, electronics and so on. Sputtering targets used in electronic industry can be subdivided into semiconductor target (also called anelva target), planar target, coated glass target, solar photovoltaic target, and so on. There are some differences in the selection and performance requirements of sputtering materials in different application fields....Continue Reading
Semiconductor wafers are the basic material for manufacturing electronic chips. The most important raw material for semiconductor integrated circuits is silicon, which is widely found in rocks and gravels in the form of silicates or silica in nature. The fabrication process of the semiconductor silicon wafer can be divided into three basic steps: silicon purification...Continue Reading
Sputtering targets are a physical vapor deposition (PVD) mechanism with many uses in modern technology and manufacturing. In the sputtering process, the atoms are pulled from the sputter target with powerful magnets, and a controlled gas (usually argon) is introduced. Then, the processed to collide with each other in their gaseous state before condensing into...Continue Reading
