PURPOSE:To improve the luminous efficiency of an illuminant by using silicon having a superiority against micro fabrication technique through a simple process. CONSTITUTION:A hydrogen-terminated dihydride structure 2 is formed on a single-crystal silicon substrate 1 on which a plurality of parallel stripe-like projections 3 are formed. The dihydride structure is formed by dipping single- crystal silicon in a hydrofluoric acid solution and terminating the surface of the silicon with hydrogen. |
