WebThe lattice-mismatch between InP and Si is 8% and 4% in respect to GaAs or Ge (see Fig. 1). The most interesting con- cept is InP on Si due to the low substrate costs. Single crystal epitaxial films of GaInAs can be deposited on a single crystal substrate of III-V semiconductor having a lattice parameter close to that of the specific gallium indium arsenide alloy to be synthesized. Three substrates can be used: GaAs, InAs and InP. A good match between the lattice constants of the film and substrate is required to maintain single crystal properties and this li…
