Germanium (Ge) wafers are ideal for semiconductor applications. Ge's high electrical conductivity means low losses. We have a large selection of single crystal and optical germanium.
Let’s focus on how the most efficient PV cells on the market are produced.

Once the rod has been sliced, the circular silicon wafers (also known as slices or substrates) are cut again into rectangles or hexagons. Two types of silicon wafers for solar cells: (a) 156-mm monocrystalline solar wafer and cell; (b) 156-mm multicrystalline solar wafer and cell; and (...
Early transistors were made of germanium or galena. However, silicon won out in the end because of several factors, such as its higher switching speed. Today, silicon wafers are cut from huge blocks of monocrystalline silicon known as boules. ...
The scale of manufacturing is also becoming smaller. CNC machines can even work on small parts such as semiconductor wafers. The degree of automation is also increasing. CNC machines are being installed on robotic arms on the assembly line to provide machinability of all parts simultaneously without...
MgAl2O4 has a spinel-type structure with high hardness, high melting point, and high strength. Pure MgAl2O4 is transparent and can be used in transparent armor, infrared windows, radome and other fields. Not only that, MgAl2O4 also has the characteristics of low εr and can also be used...
Tetramethylammonium hydroxide pentahydrate (TMAH) is a colorless crystal (often containing three or five water molecules) with an amine-like odor. It has a melting point of 68-71℃ and is highly soluble in water. When dissolved, it releases heat and forms a strongly alkaline solution with a ...
The same is true when cutting nickel-based alloys. Generally, researchers do not advocate using diamond cutting tools made out of high melting temperature metals or alloys. Additionally, diamond tool grinding is time-consuming and costly.
