Abstract

Systems and methods for large scale synthesis of germanium selenide glass and germanium selenide glass compounds are provided. Up to about 750 grams of a germanium selenide glass or a glass compound can be synthesized at a time in about eight hours or less. Stoichiometrically proportional amounts of germanium and selenium are placed in an ampoule. A variable may also be placed in the ampoule. The ampoule is heated to above the softening temperature of the glass or glass compound being synthesized. The ampoule is then rocked for a period of time while the temperature is held constant. The temperature of the ampoule is then brought down to above the softening temperature of the glass or glass compound being synthesized and then quenched.

Description

Background of the invention

[0001] The invention relates to a device and method for synthesizing germanium selenide glass and a germanium selenide glass compound. More specifically, the present invention relates to a device and method for large-scale synthesis of germanium selenide glass and germanium selenide glass compound in a shorter time. The germanium selenide glass compound referred to herein contains germanium, selenium, and variable elemental components (eg, dopants).

[0002] Germanium selenide glass is widely used in the manufacture of semiconductor devices. However, in the known preparation of a class of germanium selenide glass Ge 3 Se 7 In the current technology, only 10 grams of this glass can be prepared at a time. In addition, this method requires about 50 hours to prepare the 10 grams of germanium selenide glass.

[0003] This known technique involves placing stoichiometric amounts of germanium and selenium (not more than about 10 grams in total) in an a...
