Fa'atatauga
Bismuth telluride (Bi2Te3)ose mea fa'aeletise e iloa mo lona gafatia e fa'aliliu ai le malosi fa'avela i le malosi fa'aeletise. E masani ona aofia ai ituaiga e lua: P-ituaigaBi0.5Sb1.5Te3ma N-ituaiga Bi2Te2.7Se0.3. P-ituaiga Bi0.5Sb1.5Te3 e masani ona aofia ai bismuth, antimony ma tellurium, ae o le N-ituaiga Bi2Te2.7Se0.3 e aofia ai bismuth, tellurium ma seleni. O ituaiga uma o bismuth telluride o loʻo maua ile laulau poʻo le pauta.
O talosaga abismuth tellurideP-ituaiga Bi0.5Sb1.5Te3 ma N-ituaiga Bi2Te2.7Se0.3 e tele lava i totonu o le fanua o le thermoelectric liua malosi. O nei mea e masani ona faʻaaogaina i masini thermoelectric ua fuafuaina e faʻaogaina le eseesega o le vevela e gaosia ai le eletise. P-ituaiga Bi0.5Sb1.5Te3 ma le N-ituaiga Bi2Te2.7Se0.3 e mafai ona tuʻufaʻatasia i meafaigaluega e pei o le vevela eletise, masini faʻaleleia o le vevela o taʻavale, ma masini feaveaʻi. O le maualuga o le fa'atinoga ma le fa'aogaina e fa'aaogāina ai mo le tele o fa'aoga o le seleselega malosi.
O mea uma e lua o le P-type Bi0.5Sb1.5Te3 ma le N-type Bi2Te2.7Se0.3 bismuth telluride mea e iai mea e sili ona lelei le thermoelectric ma e fetaui lelei mo faʻaoga eletise eletise. O mea nei e mafai ona fa'aoga e fai ai mea e fa'amalie ai le thermoelectric, e ta'ua fo'i o Peltier coolers, e aveese ai le vevela mai mea fa'aeletoroni ma fa'atumauina ai le vevela sili ona lelei. I le male,Bismuth TellurideP- ma le N-ituaiga mea e faʻaaogaina mo faʻamoemoega faʻaogaina o le vevela i masini faʻafomaʻi, tekinolosi aerospace ma mea tau eletise.
I se aotelega,bismuth tellurideP-ituaiga Bi0.5Sb1.5Te3 ma le N-ituaiga Bi2Te2.7Se0.3 o mea taua ma le lautele o talosaga i le fanua o le liua malosi ma le malulu eletise. O latou uiga fa'apitoa o le thermoelectric ua avea ai i latou ma vaega taua o le tele o masini ma faiga, e saofagā i le fa'aleleia atili o le malosi ma tekonolosi fa'atumauina. A'o fa'atupula'ia le mana'oga mo le malosi fa'afouina, o le fa'aaogaina obismuth telluridemea e fa'amoemoe e fa'atupula'ia, fa'ateleina su'esu'ega ma atina'e i lea vaega.
