Question
The lattice constants of GaAs, AlAs, InAs and InP at 300K are 0.5653, 0.5660, 0.605 and 0.586 nm, respectively. Assuming the lattice constants of AlxGa1-xAs
The lattice constants of GaAs, AlAs, InAs and InP at 300K are 0.5653, 0.5660, 0.605 and 0.586 nm, respectively. Assuming the lattice constants of AlxGa1-xAs and InyGa-yAs depend linearly on X and Y.
(i) Please calculate the value of X if the density of an AlyGa,.xAs single crystal is 4.5 g/cm.
(ii) Please calculate the value of Y if the lattice constant of the epitaxy InyGa-yAs layer matches that of the InP substrate.
