A crystalline thin structure ( 104, 204, 404 ) is grown on a surface ( 108, 228 ) of a substrate ( 112, 208, 400 ) by depositing molecules ( 136, 220 ) from a molecular precursor to a lateral growth front ( 144, 224 ) of the structure using a crystal grower ( 116, 200 ). In one embodiment, the crystal grower comprises a solution ( 124 ) containing the molecular precursor in a solvent ( 140 ). Molecules are added to the lateral growth front by moving one or both of the free surface ( 120, 120 ') of the solution and deposition surface relative to the other at a predetermined rate. In another embodiment, the crystal grower comprises a mask ( 212 ) that includes at least one opening ( 216 ). Precursor molecules are vacuum deposited via a molecular beam ( 236 ) at the growth front ( 228 ) of the crystalline thin structure ( 204 ) as one or both of the opening and surface are moved relative to the other at a predetermined rate.
