Codsiga
Bismuth telluride (Bi2Te3)waa walxo koronto-dhal ah oo caan ku ah awoodda ay tamarta kulaylka u beddesho tamar koronto. Waxay inta badan ka kooban tahay laba nooc: nooca PBi0.5Sb1.5Te3iyo N-nooca Bi2Te2.7Se0.3. Nooca P-Bi0.5Sb1.5Te3 wuxuu inta badan ka kooban yahay bismuth, antimony iyo tellurium, halka N-nooca Bi2Te2.7Se0.3 uu ka kooban yahay bismuth, tellurium iyo selenium. Labada nooc ee bismuth telluride ayaa lagu heli karaa kaniini ama qaab budo ah.
Codsiyada eebismuth tellurideP-nooca Bi0.5Sb1.5Te3 iyo nooca N-Bi2Te2.7Se0.3 waxay inta badan ku jiraan goobta beddelka tamarta kulaylka. Qalabkan waxaa badanaa loo adeegsadaa aaladaha korantada ee loogu talagalay in laga faa'iidaysto kala duwanaanshaha heerkulka si loo dhaliyo koronto. Nooca P-Bi0.5Sb1.5Te3 iyo N-nooca Bi2Te2.7Se0.3 waxaa lagu dhex dari karaa qalabka sida koronto-dhaliyeyaasha, hababka soo kabashada kulaylka qashinka baabuurta, iyo hababka tamarta la qaadi karo. Waxqabadkooda sare iyo hufnaantooda ayaa ka dhigaysa inay ku habboon yihiin codsiyada goosashada tamarta ee kala duwan.
Labada nooc ee P-nooca Bi0.5Sb1.5Te3 iyo N-nooca Bi2Te2.7Se0.3 bismuth telluride maaddooyinka waxay leeyihiin sifooyin heerkulbeeg ah oo aad u fiican waxayna aad ugu habboon yihiin codsiyada qaboojinta elektiroonigga ah. Qalabkan waxaa loo isticmaali karaa in lagu abuuro qaboojiyeyaasha heerkulbeegyada, sidoo kale loo yaqaan qaboojiyeyaasha Peltier, kuwaas oo ka saara kulaylka qaybaha elektaroonigga ah oo ilaaliya heerkulka ugu fiican ee hawlgalka. Intaa waxaa dheer,Bismuth TellurideQalabka P- iyo N-nooca waxaa loo isticmaalaa ujeedooyinka maaraynta kulaylka ee aaladaha caafimaadka, tignoolajiyada hawada hawada iyo elektiroonigga macaamiisha.
Isku soo wada duuboobismuth tellurideP-nooca Bi0.5Sb1.5Te3 iyo N-nooca Bi2Te2.7Se0.3 waa maaddooyin qiimo leh oo leh codsiyo ballaaran oo dhinacyada tamarta beddelka iyo qaboojinta elektiroonigga ah. Sifooyinkooda heerkulbeegyada gaarka ah waxay ka dhigaan qayb muhiim ah oo ka mid ah aaladaha iyo nidaamyada kala duwan, iyaga oo gacan ka geysanaya horumarinta waxtarka tamarta iyo tignoolajiyada waara. Iyadoo baahida tamarta dib loo cusboonaysiin karo ay sii kordheyso, isticmaalkabismuth tellurideagabka ayaa la filayaa inuu kordho, taasoo keenaysa cilmi-baaris dheeraad ah iyo horumarinta aaggan.
