Abstract:
A monolithic device comprising a plurality of monolithically integrated layers including at least:(a) a first layer; and (b) a second layer, disposed above the first layer and operatively coupled to the first layer for communicating with the first layer; wherein: (a.1) said first layer includes a respective first single crystal material grown from a corresponding first set of spaced-apart nucleation-friendly sites whose apart spacings correspond to whole number multiples of respective lattice constants of the first single crystal material, and the spaced-apart nucleation-friendly sites of the first set thereby substantially define a first growth template which seeded growth of said first single crystal material therefrom, where each first nucleation-friendly site in said first set is defined by one or more first particles to which the material of the first single crystal material attaches more preferentially than to first surrounding material surrounding the first nucleation-friendly site, the first surrounding material being nucleation-unfriendly to the material of the first single crystal material; (b.1) said second layer includes a respective second single crystal material grown from a corresponding second set of spaced-apart nucleation-friendly sites whose apart spacings correspond to whole number multiples of respective lattice constants of the second single crystal material, and the spaced-apart nucleation-friendly sites of the second set thereby substantially define a second growth template which seeded growth of said second single crystal material therefrom, where each second nucleation-friendly site in said second set is defined by one or more second particles to which the material of the second single crystal material attaches more preferentially than to second surrounding material surrounding the second nucleation-friendly site, the second surrounding material being nucleation-unfriendly to the material of the second single crystal material.
