2inch 50.8mm Germanium Wafer Substrate Single crystal 1SP 2SP

Tsanangudzo Pfupi:

High kuchena germanium chinhu che semiconductor chinoshandiswa mukugadzira semiconductor zvishandiso. Germanium single crystal doped ine trace chaiyo tsvina inogona kushandiswa kugadzira akasiyana transistors, rectifiers uye zvimwe zvishandiso. Yakakwirira kuchena germanium imwe kristaro ine yakakwirira refraction coefficient, yakajeka kune infrared, kwete kuburikidza neinooneka uye infrared mwenje, inogona kushandiswa seprism kana lens yechiedza che infrared. Mishonga yeGermanium inoshandiswa mukugadzira mahwendefa efluorescent uye akasiyana akakwira refractive girazi. Inoshandiswawo mumagetsi emagetsi uye thermoelectric zvinhu.

Detailed Information

Germanium machipisi ane semiconductor zvivakwa. Yakaita basa rakakosha mukuvandudzwa kweiyo solid state fizikisi uye yakasimba state zvemagetsi. Germanium ine kunyungudika density ye5.32g/cm 3, germanium inogona kuverengerwa sesimbi yakatetepa yakapararira, germanium kemikari kugadzikana, haidyidzane nemhepo kana mhute yemvura pakupisa kwekamuri, asi pa600 ~ 700 ℃, germanium dioxide inokurumidza kugadzirwa. . Haishande ne hydrochloric acid, dilute sulfuric acid. Kana yakadzika sulfuric acid ichipisa, germanium inonyungudika zvishoma nezvishoma. Mu nitric acid uye aqua regia, germanium inonyungudika nyore nyore. Mhedzisiro yealkali solution pagermanium haina kusimba, asi alkali yakanyungudutswa mumhepo inogona kuita kuti germanium inyungudika nekukurumidza. Germanium haishande nekabhoni, saka inonyungudutswa mu graphite crucible uye haizosvibiswa nekabhoni. Germanium ine yakanaka semiconductor zvivakwa, senge erekitironi kufamba, kufamba kwegomba uye zvichingodaro. Kugadzirwa kwegermanium kuchiri kugona kukuru.
