Impumelelo yakamuva yentuthuko yamamojula okupholisa e-thermoelectric

I. Ucwaningo Oluphumelelayo Ngemikhawulo Yezinto Ezisetshenziswayo Nezokusebenza

1. Ukujula komqondo we-“phonon glass – electronic crystal”: •

Impumelelo yakamuva: Abacwaningi basheshise inqubo yokuhlola izinto ezingaba khona ezinokushisa okuphansi kakhulu kwe-lattice kanye ne-Seebeck coefficient ephezulu ngokusebenzisa i-high-throughput computing kanye nokufunda komshini. Isibonelo, bathole ama-Zintl phase compounds (njenge-YbCd2Sb2) anezakhiwo zekristalu eziyinkimbinkimbi kanye nama-compounds amise okwekheji, amanani awo e-ZT adlula lawo e-Bi2Te3 yendabuko ngaphakathi kwamazinga athile okushisa. •

Isu “lobunjiniyela be-Entropy”: Ukwethula ukuphazamiseka kokwakheka kwama-alloy e-entropy aphezulu noma izixazululo eziqinile zezingxenye eziningi, ezihlakaza kakhulu ama-phononi ukuze kuncishiswe kakhulu ukuhanjiswa kokushisa ngaphandle kokufaka engcupheni izakhiwo zikagesi, sekuyindlela entsha ephumelelayo yokuthuthukisa isibalo se-thermoelectric of merit.

2. Ukuthuthuka Kwasemngceleni Kwezakhiwo Eziphansi Nezakhi Ezincane:

Izinto zokushisa zikagesi ezinezinhlangothi ezimbili: Izifundo ku-SnSe enezingqimba ezimbili/i-monolayer, i-MoS₂, njll. zikhombisile ukuthi umphumela wazo wokuvalelwa kwe-quantum kanye nezimo zobuso kungaholela ezintweni zamandla eziphezulu kakhulu kanye nokushisa okuphansi kakhulu, okunikeza ithuba lokwenziwa kwama-micro-TEC amancane kakhulu, aguquguqukayo. Amamojula okupholisa e-thermoelectric amancane, ama-micro peltier coolers (izinto ze-Micro peltier).

Ubunjiniyela be-interface yesilinganiso se-nanometer: Ukulawula ngokunembile izakhiwo ezincane ezifana nemingcele yezinhlamvu, ukuhlukaniswa, kanye nokushisa kwe-nano-phase, njenge-"izihlungi ze-phonon", zisakaze ngokukhetha abathwali be-thermal (ama-phonon) ngenkathi zivumela ama-electron ukuthi adlule kahle, ngaleyo ndlela ziphule ubudlelwano bendabuko bokuxhumanisa kwamapharamitha e-thermoelectric (ukuqhuba, i-Seebeck coefficient, ukuqhuba kwe-thermal).

II. Ukuhlola Izindlela Namadivayisi Amasha Okuqandisa

1. Ukupholisa kwe-thermoelectric okusekelwe ku-on-based:

Lesi isiqondiso esisha esishintshashintshayo. Ngokusebenzisa ukufuduka kanye nokuguqulwa kwesigaba (njengoku-electrolysis kanye nokuqina) kwama-ion (esikhundleni sama-electron/imigodi) ngaphansi kwensimu kagesi ukuze kufezwe ukumuncwa kokushisa okuphumelelayo. Ucwaningo lwakamuva lubonisa ukuthi ama-gel athile e-ionic noma ama-electrolyte aketshezi angadala umehluko omkhulu kakhulu wokushisa kune-TEC yendabuko, amamojula e-peltier, amamojula e-TEC, ama-cooler e-Thermoelectric, ngama-voltage aphansi, okuvula indlela entsha ngokuphelele yokuthuthukiswa kobuchwepheshe bokupholisa besizukulwane esilandelayo obuguquguqukayo, obuthule, nobusebenza kahle kakhulu.

2. Imizamo yokunciphisa ukuqina kwefriji kusetshenziswa amakhadi kagesi namakhadi okucindezela: •

Nakuba kungewona uhlobo lomphumela we-thermoelectric, njengobuchwepheshe obuncintisanayo bokupholisa isimo esiqinile, izinto (ezifana nama-polymers kanye ne-ceramics) zingabonisa ukushintshashintsha okukhulu kwezinga lokushisa ngaphansi kwamasimu kagesi noma ukucindezeleka. Ucwaningo lwakamuva luzama ukunciphisa nokuhlanganisa izinto ze-electrocaloric/pressurcaloric, futhi luqhube ukuqhathanisa okusekelwe kumgomo kanye nokuncintisana ne-TEC, i-peltier module, i-thermoelectric cooling module, kanye nedivayisi ye-Peltier ukuze kuhlolwe izixazululo ze-micro-cooling ezinamandla aphansi kakhulu.

III. Imingcele Yokuhlanganiswa Kwesistimu Nokusungula Izinhlelo

1. Ukuhlanganiswa kwe-on-chip kokusabalalisa ukushisa “kwezinga le-chip”:

Ucwaningo lwakamuva lugxile ekuhlanganiseni i-micro TEC, imodyuli encane ye-thermoelectric， (imodyuli yokupholisa ye-thermoelectric), izakhi ze-peltier, kanye nama-chip asekelwe ku-silicon asebenza ngokufana (ku-chip eyodwa). Kusetshenziswa ubuchwepheshe be-MEMS (Micro-Electro-Mechanical Systems), ama-array amakholomu e-thermoelectric amancane enziwa ngqo ngemuva kwe-chip ukuze ahlinzeke ngokupholisa okusebenzayo "kwe-point-to-point" ngesikhathi sangempela kwezindawo ezishisayo zasendaweni zama-CPU/ama-GPU, okulindeleke ukuthi aphule imbobo yokushisa ngaphansi kokwakhiwa kwe-Von Neumann. Lokhu kubhekwa njengenye yezixazululo zokugcina zenkinga "yodonga lokushisa" yama-chip wamandla ekhompyutha wesikhathi esizayo.

2. Ukuphathwa kokushisa okuzenzela amandla kagesi agqokekayo futhi aguquguqukayo:

Ukuhlanganisa imisebenzi emibili yokukhiqizwa kwamandla kagesi okushisa kanye nokupholisa. Impumelelo yakamuva ifaka phakathi ukuthuthukiswa kwemicu ye-thermoelectric eguquguqukayo nelula futhi enamandla aphezulu. Lokhu akukwazi nje kuphela ukukhiqiza ugesi wamadivayisi agqokwayo ngokusebenzisa umehluko wokushisa， kodwa futhi kufezwe ukupholisa kwendawo (njengokupholisa iyunifomu yomsebenzi okhethekile) ngokusebenzisa ugesi obuyela emuva， ukufeza ukuphathwa kwamandla okuhlanganisiwe kanye nokushisa.

3. Ukulawula izinga lokushisa okunembile kubuchwepheshe be-quantum kanye nokuzwa kwe-bio:

Emasimini asezingeni eliphezulu njenge-quantum bits kanye nezinzwa zokuzwela okuphezulu, ukulawulwa kokushisa okunembe kakhulu ezingeni le-mK (millikelvin) kubalulekile. Ucwaningo lwakamuva lugxile ezinhlelweni ze-TEC ezinezigaba eziningi, i-peltier module (thermoelectric cooling module) ngokunemba okuphezulu kakhulu (±0.001°C) futhi luhlola ukusetshenziswa kwe-TEC module, i-peltier device, i-peltier cooler, ekukhanseleni umsindo osebenzayo, okuhlose ukudala indawo yokushisa eqinile kakhulu yamapulatifomu e-quantum computing kanye namadivayisi okuthola ama-molecule eyodwa.

IV. Ukusungula Izinto Ezintsha Kwezobuchwepheshe Bokulingisa Nokwenza Kahle

Umklamo Oqhutshwa Ubuhlakani Bokwenziwa: Ukusebenzisa i-AI (njengenethiwekhi yokukhiqiza ephikisanayo, ukufunda kokuqinisa) komklamo ophambene "wesakhiwo-ukusebenza kwezinto ezibonakalayo", ukubikezela ukwakheka kwezinto ezihlukaniswe ngezigaba eziningi kanye ne-geometry yedivayisi ukuze kufezwe i-coefficient ephezulu yokupholisa ngaphakathi kobubanzi bokushisa obubanzi, okunciphisa kakhulu umjikelezo wocwaningo nokuthuthukiswa.

Isifinyezo:

Impumelelo yakamuva yocwaningo lwe-peltier element, i-thermoelectric cooling module (i-TEC module) isuka "ekuthuthukisweni" iye "ekuguqulweni". Izici ezibalulekile yilezi ezilandelayo: •

Izinga lezinto ezibonakalayo: Kusukela ekusetshenzisweni kwezidakamizwa eziningi kuya ekusetshenzisweni kwezinga le-athomu kanye nokulawulwa kobunjiniyela be-entropy.

Ezingeni eliyisisekelo: Kusukela ekuthembeleni kuma-electron kuya ekuhloleni izithwali ezintsha zokushaja ezifana nama-ion nama-polaron.

Izinga lokuhlanganisa: Kusukela ezingxenyeni ezihlukene kuya ekuhlanganisweni okujulile nama-chips, izindwangu, namadivayisi ebhayoloji.

Izinga eliqondiwe: Ukusuka ekupholiseni kwezinga elikhulu kuya ekubhekaneni nezinselele zokuphathwa kokushisa kobuchwepheshe obusezingeni eliphezulu njenge-quantum computing kanye ne-optoelectronics ehlanganisiwe.

Lokhu kuthuthuka kubonisa ukuthi ubuchwepheshe bokupholisa be-thermoelectric besikhathi esizayo buzosebenza kahle kakhulu, bube buncane, buhlakaniphe, futhi buhlanganiswe ngokujulile enkabeni yobuchwepheshe bolwazi besizukulwane esilandelayo, ubuchwepheshe be-bio, kanye nezinhlelo zamandla.
