Strain of material w. (111) orientation is asymmetric about center point? Why?

    strain of material w. (111) orientation is asymmetric about center point? Why??

    My calculation shows an asymmetric strain distribution in InAs/GaAs(111) heterostructure while it is symmetric in InAs/GaAs(001).

    Someone could give explanation on it??

    How was your calculations done?

    Since the strain is pointwise scalar, what i did is just to calculate one strain component along a particular direction, such as:
    exx along x [100] direction, etc.
