Framework assisted crystal growth
View Patent ↗A method for growing a crystal includes steps of providing a 3D framework with an collection of solid structures and flowing a liquid starting material around and between individual ones of the solid structures of the 3D framework. The method also includes a step of growing a single crystal through the collection of solid structures by adjusting a property of the liquid starting material.
1. A method for growing a crystal, comprising:
providing a 3D framework having a collection of solid structures;
flowing a liquid starting material around and between individual ones of the solid structures of the 3D framework; and
growing a single crystal through the collection of solid structures by adjusting a property of the liquid starting material; and
wherein the liquid starting material has a different chemical composition than the crystal.
2. The method of claim 1 , wherein the growing comprises a transition from an amorphous phase of a material to a crystalline phase of the material.
3. The method of claim 1 , wherein the growing is responsive to diffusing a gaseous material into the liquid starting material.
4. The method of claim 1 , wherein the 3D framework comprises an engineered nucleation site, and the growing causes the crystal to nucleate at the engineered nucleation site.
5. The method of claim 1 , wherein the 3D framework further comprises a coating on a portion of the 3D framework, the coating inhibiting nucleation of a crystal on the coated portion of the 3D framework.
6. The method of claim 1 , wherein the collection of solid structures forms a pattern with a regular lattice symmetry.
7. The method of claim 1 , wherein the lattice symmetry is a two-dimensional symmetry.
8. The method of claim 1 , wherein the growing causes a byproduct material of the growth to collect adjacent to the solid structures, the byproduct material having a composition that is different from compositions of both the crystal and the liquid starting material.
9. The method of claim 1 , wherein the growing produces a single crystal with a linear dimension of at least 100 microns.
10. An apparatus, comprising:
a layer formed of a single crystal, the layer having a collection of holes in the layer; and
wherein the collection of holes forms a pattern having a regular lattice symmetry and the crystal comprises an organic material or a zeolite.
11. The apparatus of claim 10 ,
wherein the holes are substantially identical; and
wherein the layer forms an optical grating.
12. The apparatus of claim 10 , wherein the layer forms a photonic bandgap structure.
13. The apparatus of claim 11 , wherein the layer is a birefringent crystal.
14. The apparatus of claim 10 , wherein the pattern of holes has a 2-dimensional lattice symmetry.
15. The apparatus of claim 10 , further comprising:
a collection of solid structures, each structure being located in one of the holes and having a different composition than the layer.
16. The apparatus of claim 15 , wherein the collection has a 2-dimensional lattice symmetry.
17. The apparatus of claim 10 , wherein adjacent ones of the holes have separations of less than about 20 microns.
18. The apparatus of claim 10 , wherein the holes pierce through the layer.
19. The apparatus of claim 10 , wherein the holes of the collection are substantially identical.
20. The apparatus of claim 19 , wherein the pattern of holes has a 2-dimensional lattice symmetry.
