A two-dimensional vertical heteroepitaxial strain controlled composite is grown. The strain-controlling phase can be benign in all other respects so that the functional properties of the parent phase are unchanged, improved/enhanced, and/or manipulated. The new composite is advantageous because there is no need for expensive specialized crystals and because there are no thickness limitations.
