Bismuth telluride (Bi2Te3)He mea thermoelectric i ʻike ʻia no kona hiki ke hoʻololi i ka ikehu wela i ka ikehu uila. Nui nā ʻano ʻelua: P-typeBi0.5Sb1.5Te3a me N-ʻano Bi2Te2.7Se0.3. P-type Bi0.5Sb1.5Te3 ka nui o ka bismuth, antimony a me tellurium, aʻo N-type Bi2Te2.7Se0.3 ka bismuth, tellurium a me selenium. Loaʻa nā ʻano bismuth telluride ʻelua ma ka papa a i ʻole ka pauka.
ʻO nā noi obismuth tellurideP-type Bi0.5Sb1.5Te3 a me N-type Bi2Te2.7Se0.3 ka mea nui ma ke kahua o ka hoololi ikehu thermoelectric. Hoʻohana pinepine ʻia kēia mau mea i nā mea thermoelectric i hoʻolālā ʻia e hoʻohana i nā ʻokoʻa wela e hana ai i ka uila. Hiki ke hoʻohui ʻia ka P-type Bi0.5Sb1.5Te3 a me ka N-type Bi2Te2.7Se0.3 i loko o nā lako e like me nā mea hoʻoheheʻe thermoelectric, nā ʻōnaehana hoʻolaʻa wela kaʻa, a me nā ʻōnaehana hoʻomohala uila. ʻO kā lākou hana kiʻekiʻe a me ka maikaʻi e kūpono iā lākou no nā ʻano hana ʻohi ikehu.
ʻO nā mea ʻelua P-type Bi0.5Sb1.5Te3 a me N-type Bi2Te2.7Se0.3 bismuth telluride mau mea ʻano thermoelectric maikaʻi loa a kūpono loa no nā noi hoʻomehana uila. Hiki ke hoʻohana ʻia kēia mau mea no ka hana ʻana i nā mea hoʻoluʻu thermoelectric, i kapa ʻia ʻo Peltier coolers, e hoʻoneʻe i ka wela mai nā mea uila a mālama i nā mahana hana maikaʻi loa. Kahi mea hou aʻe,ʻO Bismuth TellurideHoʻohana ʻia nā mea P- a me N-type no nā kumu hoʻokele wela i nā mea lapaʻau, ʻenehana aerospace a me nā mea uila uila.
I ka hōʻuluʻulu manaʻo,bismuth tellurideʻO ka P-type Bi0.5Sb1.5Te3 a me ka N-type Bi2Te2.7Se0.3 he mau mea waiwai me ka hoʻohana ākea ma nā kahua o ka hoʻololi ʻana i ka ikehu a me ka hoʻoluʻu uila. ʻO kā lākou mau waiwai thermoelectric kūʻokoʻa e lilo lākou i mea koʻikoʻi o nā ʻano mea like ʻole a me nā ʻōnaehana, e hāʻawi ana i ka holomua o ka ikehu a me nā ʻenehana hoʻomau. Ke hoʻomau nei ka noi no ka ikehu hou, hoʻohana ʻiabismuth telluridemanaʻo ʻia e piʻi aʻe nā mea waiwai, e hoʻoikaika ana i ka noiʻi a me ka hoʻomohala ʻana ma kēia wahi.
