## Modified atomic scattering amplitudes and size effects on the 002 and 220 electron structure factors of multiple $Ga_{1-x}In_{x}As/GaAs$ quantum wells University of Antwerp

The modified atomic scattering amplitudes (MASAs) of mixed Ga1-xInxAs, GaAs1-xNx, and InAs1-xNx are calculated using the density functional theory approach and the results are compared with those of the binary counterparts. The MASAs of N, Ga, As, and In for various scattering vectors in various chemical environments and in the zinc-blende structure are compared with the frequently used Doyle and Turner values. Deviation from the Doyle and ...
