Intrinsic amorphous silicon
Did you know?
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. Amorphous silicon … See more Silicon is a fourfold coordinated atom that is normally tetrahedrally bonded to four neighboring silicon atoms. In crystalline silicon (c-Si) this tetrahedral structure continues over a large range, thus forming a well-ordered … See more The density of amorphous Si has been calculated as 4.90×10 atom/cm (2.285 g/cm ) at 300 K. This was done using thin (5 micron) strips of … See more While a-Si suffers from lower electronic performance compared to c-Si, it is much more flexible in its applications. For example, a-Si layers can be made thinner than c-Si, which … See more • Amorphous Silicon Devices group at the University of Waterloo, Ontario, Canada • Theory and Simulation at Ohio University, Athens Ohio See more Amorphous alloys of silicon and carbon (amorphous silicon carbide, also hydrogenated, a-Si1−xCx:H) are an interesting variant.
