(10 points ) for a strained-laver superlattice of equal-thickness layers Of GangIng-P and GapIn P (see figure below) on a GaAs substrate, determine the value of x which neutralizes shear force at the GaAs interface with the first layer of the superlattice. Will the answer be different if the layers are not of equal thickness? Assume Vegard's law and equal thermal- expansion coefficients.
