![]() Silicon Lattice Constant Lattice Parameter of Silicon In this orientation, each silicon atom has four neighbouring silicon atoms that it is bound to. Each carbon atom is bound by a covalent bond sharing the electronic doublet with the four neighbouring carbon atoms, with the result of creating a lattice stretching out in each direction through an enormous number of elementary cells, creating a crystal with a covalent lattice. The silicon lattice has a diamond-like structure, in which every Si atom has four nearby neighbors connected through covalent bonds, creating tetrahedrons, which are space-periodic, as seen in the diagram. The other thing I'd like to take the chance to check with you for another project: we are also considering to have a layer of single crystalline, undoped epitaxial GaAs layer (thickness= 360 nm) on fused silica substrate (3" or 4"), and I was just wondering if this is something that can be provided by university wafers, or we just need to ask MBE/MOCVD grower to do the epilayer growth on GaAs substrate, and then do the wafer bonding on our own?"īelow are the Typical Terms Associate With Silicon Lattice I was just wondering if this can be customized? I thought about this more carefully, and I think it might not be doable to put (grow or deposit) an epi silicon layer on top of glass substrate, due to the lattice mismatch and maybe other factors?Īfter more discussion with my colleague, it seems that we just need to put down a layer of amorphous Si instead of epi Si, due to its lower optical loss. "We are looking for glass substrate (2 or 3") with an epi Si layer (thickness ~ 400 nm). A scientist requested a quote for their following research project. ![]()
