Ukusebenza

I-TIG-BiTe-P/N-2 ingot ye-thermoelectric ikhuliswa nge-alloy ye-Bi, Sb, Te, Se, i-doping ekhethekile kanye nezinqubo zethu eziyingqayizivele zokucwebezela. IBi2Te3-based thermoelectric ingot ikhuliswe ngokukhethekile futhi yalungiselelwa ukwenza amamojula we-thermoelectric asetshenziselwa ukuguqula umthombo wokushisa osuka ku-100℃(373K) ukuya ku-350℃(623K) abe ugesi. Ngokuvamile, isilinganiso sesilinganiso se-ZT sohlobo lwethu lwe-p kanye ne-n-type ingots ebangeni lokushisa elingu-300K kuya ku-600K sikhulu kuno-0.7. Imojula eyenziwe ngama-ingots anjalo ingakwazi ukufeza ukusebenza kahle okungu-5% nge-250℃ Delta T. Phakathi naleso sikhathi, ingot yethu iboniswa ngamandla omshini omuhle kanye nempahla ezinzile, ehlinzeka ngetshe eliyinhloko lokukhiqiza ukusebenza okuphezulu kanye namamojula okukhiqiza amandla athembekile.

Isicelo

I-Bismuth telluride (Bi2Te3)i-thermoelectric material eyaziwa ngekhono layo lokuguqula amandla ashisayo abe amandla kagesi. Ikakhulukazi yakhiwe izinhlobo ezimbili: uhlobo lwe-PI-Bi0.5Sb1.5Te3kanye nohlobo lwe-N lwe-Bi2Te2.7Se0.3. I-P-type Bi0.5Sb1.5Te3 yakhiwe ngokuyinhloko i-bismuth, i-antimony ne-tellurium, kuyilapho i-N-type Bi2Te2.7Se0.3 iqukethe i-bismuth, i-tellurium ne-selenium. Zombili izinhlobo ze-bismuth telluride ziyatholakala ngethebhulethi noma ngefomu lempushana.

Izicelo zei-bismuth tellurideI-P-type Bi0.5Sb1.5Te3 kanye ne-N-type Bi2Te2.7Se0.3 ikakhulukazi emkhakheni wokuguqulwa kwamandla kagesi we-thermoelectric. Lezi zinto zivame ukusetshenziswa emishinini ye-thermoelectric eklanyelwe ukusizakala ngokuhluka kwezinga lokushisa ukuze kukhiqizwe ugesi. I-P-type Bi0.5Sb1.5Te3 kanye ne-N-type Bi2Te2.7Se0.3 ingahlanganiswa emishinini efana namajeneretha e-thermoelectric, amasistimu okuthola ukushisa kwemfucuza yezimoto, kanye nezinhlelo eziphathwayo zokuphehla amandla. Ukusebenza kwabo okuphezulu nokusebenza kahle kubenza bafanelekele izinhlelo zokusebenza ezihlukahlukene zokuvuna amandla.

Kokubili P-type Bi0.5Sb1.5Te3 kanye N-uhlobo Bi2Te2.7Se0.3 bismuth telluride izinto zinezici thermoelectric ezinhle kakhulu futhi zifaneleka kakhulu izicelo zokupholisa electronic. Lezi zinto zingasetshenziswa ukwakha izipholile ze-thermoelectric, ezaziwa nangokuthi ama-Peltier coolers, asusa ukushisa ezingxenyeni ze-elekthronikhi futhi agcine izinga lokushisa elilungile lokusebenza. Ngaphezu kwalokho,I-Bismuth TellurideIzinto zokwakha zohlobo lwe-P no-N zisetshenziselwa izinjongo zokulawula ukushisa kumishini yezokwelapha, ubuchwepheshe be-aerospace kanye nama-electronics abathengi.

Ngokufigqiwe,i-bismuth tellurideI-P-type Bi0.5Sb1.5Te3 kanye nohlobo lwe-N-Bi2Te2.7Se0.3 yizinto ezibalulekile ezisetshenziswa kabanzi emikhakheni yokuguqulwa kwamandla kanye nokupholisa nge-elekthronikhi. Izakhiwo zabo ezihlukile ze-thermoelectric zibenza babe ingxenye ebalulekile yezinhlobonhlobo zamadivayisi nezinhlelo, ezifaka isandla ekuthuthukisweni kokusebenza kahle kwamandla kanye nobuchwepheshe obuqhubekayo. Njengoba isidingo samandla avuselelekayo siqhubeka sikhula, ukusetshenziswa kwei-bismuth tellurideizinto zokwakha kulindeleke ukuthi zande, ziqhube ucwaningo nokuthuthukiswa okuqhubekayo kule ndawo.
