    Abstract: An efficient converter of photon energy to heat has been devised comprising a dense array of metal whiskers grown with spacings between the whiskers of a few wavelengths of visible light. The material selected, and tungsten is exemplary of such materials, has low emissivity, but achieves significant optical absorption by trapping the light impinging on the dense array by a geometric maze effect. The characteristics of the surface are excellent for the conversion of solar energy to heat.

    Abstract: ANNEALING OF ION IMPLANTED III-V COMPOUNDS Thermal decomposition is reduced and stoichiometry is retained during annealing of a multiple element intermetallic semiconductor material by heating it in an environment with an excess of the most volatile constituent. In particular, a GaAs wafer is annealed with a surface into which Si has been implanted while the surface is in proximity to InAs.
