    摘要: In a semiconductor light-emitting element, an underlayer is made of a high crystallinity Al-including semiconducting nitride material of which the FWHM is 90 seconds or below in full width at half maximum of an X-ray rocking curve. A light-emitting layer is made of a semiconducting nitride material including it least one element selected from the group consisting of Al, Ga and In and containing at least one element selected from rare earth metal elements. The light-emitting layer can be omitted if at least one element selected from rare earth metal elements is incorporated in the underlayer.

    摘要: Using a thin plate seed crystal 10 having a different material from a bulk crystal to be grown and having a great diameter, before crystal growth is started, a temperature in the lower portion of a solution 12s in which material is solved into a solvent (or a melt 12m) is set to a higher temperature than the upper portion to cause convection so that the surface of seed crystal 10 is rinsed by the convection by keeping in the state for a predetermined period. Then, the crystal growth is started by the Bridgman method or gradient freezing method. In this case, a temperature gradient may be provided on the surface of seed crystal 10 by inclining the seed crystal 10 such that nucleation of crystal growth is generated at a position whose temperature is lowest on the surface of seed crystal 10 upon the start of crystal growth, or a small concave or protrusion portion may be formed in advance on the surface of seed crystal 10 such that nucleation of crystal growth is generated at the small concave or protrusion portion. Thereby, a bulk single crystal of good quality can be manufactured with a high yield.

    摘要: A process for growing a multielement compound single crystal, includes the steps of placing a crucible holding a raw multielement compound of a predetermined set of composition ratios Y in a vertical crystal growing furnace having a heater, melting the raw multielement compound held in the crucible with the heater to produce a melt of the raw multielement compound in the crucible, controlling the output of the heater to grow a multielement compound single crystal of a predetermined set of composition ratios X from the melt so that the melt is solidified successively upwards from part of the melt in contact with the bottom of the crucible, and feeding to the melt as a solute at least one element of the raw multielement compound from above the level of the melt in the crucible so as to maintain the predetermined set of composition ratios X of the solute during growth of the multielement compound single crystal. The process can keep constant the composition of the grown multielement compound single crystal. The process is applicable to the growth of multielement compound semiconductor single crystals and multielement compound oxide single crystals.
