Abstract

FIELD: electronic engineering. SUBSTANCE: the chalcogenide glass comprises (wt % ): 65-70 tellurium; 10-15 thallium; 2-5 arsenic; 12-15 indium; and 2-3 boron. The glass has a forbidden zone of 0.15-0.2 eV. EFFECT: improved properties of the chalcogenide glass. 1 tbl

Description

Изобретение относится к составам халькогенидных стекол, используемых, преимущественно в электронике. The invention relates to compositions of chalcogenide glasses used primarily in electronics.

Известно халькогенидное стекло, содержащее следующие ингредиенты, мас. % : Te 40-80; As 20-60. Known chalcogenide glass containing the following ingredients, wt. %: Te 40-80; As 20-60.

Известно халькогенидное стекло, содержащее следующие ингредиенты, мас. % : Te 44-64; Tl 30-50; As 1-12. Запрещенная зона такого стекла составляет 0,3-0,57 эВ. Known chalcogenide glass containing the following ingredients, wt. %: Te 44-64; Tl 30-50; As 1-12. The forbidden zone of such a glass is 0.3-0.57 eV.

Цель изобретения - уменьшение запрещенной зоны. The purpose of the invention is the reduction of the forbidden zone.

Это достигается тем, что в состав стекла дополнительно вводят In и В при следующем соотношении ингредиентов, мас. % : Te 65-70; Tl 10-15; As 2-5; In 12-15; В 2-3. This is achieved by the fact that In and In are additionally introduced into the glass composition in the following ratio of ingredients, wt. %: Te 65-70; Tl 10-15; As 2-5; In 12-15; In 2-3.

В таблице приведены конкретные составы халькогенидного стекла и величина запрещенной зоны. The table shows the specific compositions of chalcogenide glass and the magnitude of the forbidden zone.

Предложенное стекло получают в электропечи при температуре 1000оС. В остальном технология получения предложенного стекла та же, что и известного.The proposed glass was obtained in an electric furnace at 1000 ° C. The rest of the proposed technology for producing glass is the same as the known one.
