Provided is a self-supporting polycrystalline GaN substrate composed of GaN-based single crystal grains having a specific crystal orientation in a direction approximately normal to the substrate. The crystal orientations of individual GaN-based single crystal grains as determined from inverse pole figure mapping by EBSD analysis on the substrate surface are distributed with tilt angles from the specific crystal orientation, the average tilt angle being 1 to 10°. There is also provided a light emitting device including the self-supporting substrate and a light emitting functional layer, which has at least one layer composed of semiconductor single crystal grains, the at least one layer having a single crystal structure in the direction approximately normal to the substrate. The present invention makes it possible to provide a self-supporting polycrystalline GaN substrate having a reduced defect density at the substrate surface, and to provide a light emitting device having a high luminous efficiency.

The process includes processing a molten phase of semiconductor material ering a solid phase of the material and having a free surface opposite this solid phase, into which, during the crystallization procedure, energy is radiated and material is fed in in granular form, which material floats and is melted. As a result, at the opposite solid/liquid interface, material grows on the solid phase which is drawn downwards in accordance with the growth rate. The process allows mono- or polycrystalline rods or blocks to be obtained. The main advantages of the process are that it can be carried out without melting vessels, it is possible to use granular material, and the energy balance is favorable because of the small amounts of melt.

A lithium metal negative electrode for an electrochemical cell for a secondary lithium metal battery includes a polycrystalline metal substrate having a major facing surface with a defined crystallographic texture. An epitaxial lithium metal layer is formed on the major facing surface of the polycrystalline metal substrate. The epitaxial lithium metal layer exhibits a predominant crystal orientation. The predominant crystal orientation of the epitaxial lithium metal layer is derived from the defined crystallographic texture of the major facing surface of the polycrystalline metal substrate.

An apparatus and method is provided for coating a surface of a material with a film of porous coordination polymer. A first substrate having a first surface to be coated is positioned in a processing chamber such that the first surface is placed in a substantially opposing relationship to a second surface. In some embodiments, the second surface is provided by a wall of the processing chamber, and in other embodiments the second surface is provided by a second substrate to be coated. The first substrate is held such that a gap exists between the first and second surfaces, and the gap is filled with at least one reaction mixture comprising reagents sufficient to form the crystalline film on at least the first surface. A thin gap (e.g., having a thickness less than 2 mm) between the first and second surfaces is effective for producing a high quality film having a thickness less than 100 μm. Confining the volume of the reaction mixture to a thin layer adjacent the substrate surface significantly reduces problems with sedimentation and concentration control. In some embodiments, the size, shape, or average thickness of the gap is adjusted during formation of the film in response to feedback from at least one film growth monitor.
