Abstract
A surface-transformation method of forming regions of a second material in a first solid material to control the properties of the first solid material is disclosed. The regions of the second material are formed in the first solid material by drilling holes to a predefined depth and at a predefined lattice position. The holes in the first solid material are then filled with a second material and then the first and second materials are heated to a temperature close to the melting point of the first solid material to spontaneously form the regions filled with the second material and embedded in the first solid material at the desired location. A liquid-phase immersion method or a deposition method may be employed to fill the holes in the first solid material.
Claims14
A solid material having spatial regions arranged therein in a predefined pattern, said spatial regions being surrounded by said solid material and providing said solid material with a predetermined energy particle diffraction pattern, said spatial regions comprising a material different from said solid material, said solid material having a melting temperature higher than the melting temperature of said different material.
A solid material having regions arranged within said solid material in a periodic array, said regions being completely surrounded by said solid material and having different particle diffraction patterns than said solid material without regions, said regions comprising a material different from the material of said solid material, wherein said solid material includes silicon dioxide and said material of said regions is selected from the group consisting of aluminum, silicon and germanium.
