Ukusetshenziswa kwezinto ezintsha ze-thermoelectric ezindaweni ezisezingeni eliphezulu kuthuthuka ngokushesha, kuqhutshwa yintuthuko eguqukayo kwisayensi yezinto. Okuphawulekayo ukuthi ukuhlanganiswa okuhlangene kokuguquguquka kanye nokunciphisa amandla kukhulule ubuchwepheshe bokupholisa be-thermoelectric emikhawulweni yezakhiwo eziqinile ezivamile, ngaleyo ndlela kuvulwe imingcele emisha yokusetshenziswa kuzo zonke izigaba eziningi zobuchwepheshe obuphezulu:
Izicelo Zesikhumba Nokunakekelwa Kwezempilo Eziguquguqukayo Ze-elekthronikhi
Ukuvela kwezinto eziguquguqukayo ze-thermoelectric ezingaphili—njengezinhlanganisela ezisekelwe ku-bismuth telluride (Bi₂Te₃) kanye ne-silver chalcogenides—kunqobe ukuhwebelana okude phakathi kokusebenza okuphezulu kwe-thermoelectric kanye nokukhubazeka kwemishini.
Ukunciphisa Ama-Hot-Spot e-Microscale: Ama-cooler e-thermoelectric asekelwe ku-Bi₂Te₃ amancane kakhulu, amamojula okupholisa e-thermoelectric (amamojula e-Peltier) afinyelela ukwehla kwezinga lokushisa okungaphezu kuka-10 °C ngaphansi komthamo omncane wokufaka (isb., 84 mA), ngesikhathi sokuphendula esishisayo esisheshayo esingaba ngu-25 μs. Lokhu kwenza ukuphathwa kokushisa okunembile, kwendawo yamasekethe ahlanganisiwe anamandla aphezulu, ngaleyo ndlela kuthuthukiswe ukuthembeka kwama-chip kanye nokuzinza kokusebenza.
Amadivayisi Ezokwelapha Agqokwayo Nafakelwayo: Ngenxa yokunamathela kwawo okufana nezicubu zezinto eziphilayo—njengesikhumba se-elekthronikhi—amadivayisi e-thermoelectric aguquguqukayo, amadivayisi e-peltier, (amamojula e-thermoelectric) enza imisebenzi emibili: (i) ukuqoqa amandla okushisa kusuka kuma-gradient omzimba kuya ezindaweni ezizungezile kuya ezinzwa ze-biomedical ezinamandla aphansi kakhulu (isb., iziqaphi zenhliziyo eziqhubekayo); kanye (ii) ukuvumela ukuzwa kokushisa okunembile kakhulu, okuxazululwe ngokwendawo ukuze kutholakale kusenesikhathi ukuvuvukala kwendawo, ukuhlolwa kokuphazamiseka kokuphuma kwegazi okungaphandle, kanye nokulawulwa kokushisa okusebenzayo kumadivayisi afakelwayo esizukulwane esilandelayo—kufaka phakathi izixhumi ze-neural kanye nezixhumi ze-brain-computer.
Izindawo Ezibucayi Nezinhlelo Zezindiza
Ukuvuthwa kwezimboni kwama-semiconductor e-wide-bandgap esizukulwane sesithathu—ikakhulukazi i-silicon carbide (SiC) kanye ne-gallium nitride (GaN)—kuyandisa kancane kancane ukusebenza kwamadivayisi e-semiconductor, amamojula e-thermoelectric, amamojula e-TEC (amamojula e-peltier) ezimweni ezimbi kakhulu.
Ukuzwa Kwezinga Lokushisa Eliphezulu Nokulawula Ukushisa: I-voltage yangaphakathi yokuwohloka okuphezulu, ukuzinza kokushisa okumangalisayo, kanye nokubekezelela imisebe ye-SiC ne-GaN kwenza kube nokusebenza okuqinile kwezinhlelo zokulawula ukushisa ezisebenzayo kanye nezinhlelo zokulawula ukushisa ezisebenza ezindaweni ezibalulekile—kufaka phakathi amapulatifomu ezindiza kanye nokuqapha inqubo yezimboni ezishisa kakhulu—lapho ukunemba okuqinile, ukuthembeka, kanye nokuphila isikhathi eside kubaluleke kakhulu.
Amarobhothi Ahlakaniphile Nokuqonda Okuthintayo
Ukusungula izinto ezintsha kudlulela ngale kokuphathwa kokushisa ukuze kusekelwe intuthuko ephelele kuma-elekthronikhi aguquguqukayo. Isibonelo, abacwaningi baklame inzwa yokuthinta esebenzayo esebenzisa ama-semiconductors anezici ezimbili amancane kakhulu, ahambisana nomshini (isb. i-molybdenum disulfide). Uma ihlanganiswe kuma-grippers athambile e-robotic, le nzwa ithola izisusa zokucindezela ezingeni eliphansi le-millipascal—ezilingana namandla amnene omoya esikhumbeni somuntu—ngaleyo ndlela inika imishini amandla okuthinta afana nawomuntu. Ukuhlangana kokuqonda okunjalo kokuthinta okuphezulu nokulawula ukushisa okuguqukayo kusungula ipulatifomu yehadiwe eyisisekelo yezinhlelo ze-robotic ezizimele ze-biomimetic zesikhathi esizayo.
Ukuhumusha Kwezimboni Nobukhosi Bobuchwepheshe Basekhaya
Ezweni lakithi, imizamo ehlangene yezikhungo zocwaningo kanye nababambiqhaza embonini isheshisa ukuguquka kwezinto ezintsha ezisezingeni lelebhu zibe imikhiqizo ephumelelayo kwezentengiselwano. Icala elimele yiShanghai Institute of Ceramics, iChinese Academy of Sciences, enikeze amalayisense amaningi kuma-thermoelectrics epulasitiki angaphilile—okwenza kube lula ukuwasebenzisa ekuzinziseni ukushisa kwe-module ye-optical, ukusatshalaliswa kokushisa kwezinga le-chip elithuthukisiwe, kanye nezinhlelo zokusebenza ze-microsensor ezizisebenzisayo. Lokhu kuthuthuka kubonisa intuthuko eqhubekayo yeShayina ekuzimeleleni kwezobuchwepheshe ezintweni ze-semiconductor ezithuthukisiwe, ukunciphisa ukuthembela ezinketheni zokuphakelwa kwamanye amazwe kanye nokuqinisa amandla asekhaya okusungula izinto ezintsha ngamasu.
