Amorphous steel is limited to foils of about 50 μm thickness. The mechanical properties of amorphous steel make stamping laminations for electric motors difficult. Since amorphous ribbon can be cast to any specific width under roughly 13 inches and can be sheared with relative ease, it is a suitable material for wound electrical transformer cores.
Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs.. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic.
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms .
An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. [1] The magnetic core of this transformer is made with a ferromagnetic amorphous metal . The typical material ( Metglas ) is an alloy of iron with boron , silicon , and phosphorus in the form of thin (e.g. 25 μm) foils rapidly cooled from melt.
Because it is naturally abundant and well understood, amorphous or polycrystalline silicon were (and still are) used as the semiconductor layer. However, because of the low mobility of amorphous silicon [2] and the large device-to-device variations found in polycrystalline silicon, [3] [4] [5] other
Directly behind the scintillator layer is an amorphous silicon detector array manufactured using a process very similar to that used to make LCD televisions and computer monitors. Like a TFT-LCD display, millions of roughly 0.2 mm pixels each containing a thin-film transistor form a grid patterned in amorphous silicon on the glass substrate. [1]
Polycrystalline silicon (p-Si) is a pure and conductive form of the element composed of many crystallites, or grains of highly ordered crystal lattice.In 1984, studies showed that amorphous silicon (a-Si) is an excellent precursor for forming p-Si films with stable structures and low surface roughness. [2]
The making of metal sheet often involves compression in one direction and, in efficient rolling operations, tension in another, which can orient crystallites in both axes by a process known as grain flow. However, cold work destroys much of the crystalline order, and the new crystallites that arise with annealing usually have a different texture.
