    摘要: Photoelectrochemical etching of gallium arsenide in highly alkaline aqueous solution yields optically smooth etched surfaces suitable for many optical devices. Higher optical quality is obtained for lower irradiation energy provided sufficient energy is available to produce holes in the valence band.

    摘要: A palladium electroplating process is described in which a unique compound is used to supply palladium to the electroplating bath. The procedure is particularly useful where a polyamine such as 1,3-diaminopropane is used as the complexing agent for palladium in a palladium electroplating bath. The unique compound is palladium-1,3-diaminopropanedichloride which is highly stable, can be made in pure form, and is readily soluble in water, aqueous solutions, and typical palladium baths.

    摘要: A palladium electroplating procedure is disclosed which permits rapid and efficient plating and yields ductile, adherent palladium films. The electroplating bath comprises a unique palladium complex. The procedure is also useful for electroplating a variety of palladium alloys. In addition, the bath is highly stable and does not adversely affect the base material being plated.
