Abstract:
An improved electromagnetic wave-emitting device is provided. A high pressure is applied to the device by potting the device in a suitable encapsulant. The potted device exhibits a decreased threshold current density and an increase in its efficiency. Additionally, the device has a more durable structure and an increased shelf life.

[Also in Group XXXVI] A P type monocrystalline germanium wafer shaped as described in Group XXXVI is placed in a sealed chamber 17 with finely divided 0À01 ohm. cm. phosphorus doped N type germanium 18 and germanium iodide as a carrier gas. The finely divided germanium source 18 is maintained at 550‹C., the wafer at 400‹C, and the rest of the chamber at 410‹C. for 48 hours during which the germanium is transported from source 18 and deposited epitaxially at 7 on the wafer.
Abstract:
Disclosed is a method of electrolessly plating an alloy onto a substrate. To plate an alloy consisting of two elements requires the steps of mixing two solutions, each containing one of the elements to be alloy plated, and immersing a surface to be plated in said mixed solution for a fixed period of time until a desired thickness of alloy has been plated onto the surface.
