Ngexesha lokusebenza kwe-transistor, kwakheka umjelo wemingxunya, ngelixa umaleko wombane ophindwe kabini obangelwa yi-cation
Abaphandi beYunivesithi yeSizwe yaseSeoul baphuhlise i-transistor ye-electrochemical organic ekhupha ukukhanya engaphantsi kakhulu enokwenza ngaxeshanye ukucubungula isignali, imemori kunye nokukhupha ukukhanya ngaphakathi kwesixhobo esinye se-semiconductor. Ngokungenisa i-ion-transport enhancer kwitshaneli ye-polymer ekhupha ukukhanya, iqela lenze ukuba ukwenziwa kombane-kabini-umaleko kwindawo yokudibanisa i-drain electrode, okuvumela ukujova kwe-electron okusebenzayo ngaphandle kokuxhomekeka kwi-voltage ephezulu okanye i-n-type doping engazinzile esetyenziswa kwiindlela eziqhelekileyo.
Ngenxa yoko, esi sixhobo sagcina isakhiwo esilula esisebenza ngombane omnye ngelixa sisebenza nge-low voltage kunye nokukhupha ukukhanya okubanzi, okufakwe kwindawo, kunye nokusebenza kokucubungula isignali ye-neuromorphic.
Lo msebenzi upapashwe kwijenali iNature Materials.
Izixhobo ze-elektroniki ezinxitywayo ziyatshintsha ngokukhawuleza ngaphaya kwee-smartwatches kunye neeglasi ezikrelekrele zibe ngamaqonga alula okusebenziseka kwisizukulwana esilandelayo, kunye nokwandiswa kwexesha elizayo ukuya kwizixhobo ezifakwe eluswini nakwizixhobo ezifakelwayo.
Ngokukodwa, izixhobo ezinxitywayo eluswini, kunye neetekhnoloji ze-semiconductor ezidibeneyo ezidibanisa ukuva, ukucubungula imiqondiso, inkumbulo kunye nemisebenzi yokubonisa kwiqonga elinye, zithathwa njengeetekhnoloji ezibalulekileyo ezivumela ukhathalelo lwempilo lwesizukulwana esilandelayo kunye nomzi-mveliso we-elektroniki wexesha elizayo.
Kutshanje, izixhobo ze-elektroniki ezinxitywayo ziye zaphucuka ngaphaya kokufunyanwa kwesignali yebhayoloji ukuya ekucwangcisweni kwesignali ngexesha langempela kunye nokubonakala.
Nangona kunjalo, kude kube ngoku, le misebenzi ibisoloko isetyenziswa kusetyenziswa izixhobo ezidityanisiweyo ezahlukeneyo, nto leyo ebangela izakhiwo ezintsonkothileyo, izinto ezinkulu neziqinileyo, kunye nokusetyenziswa kwamandla aphezulu. Ke ngoko, ukudibanisa imisebenzi emininzi ngaphakathi koyilo lwesixhobo esilula kube ngumceli mngeni omkhulu.
1. Kutheni izixhobo zangoku zingaphumeleli
Iitransistors ezikhupha ukukhanya kwezinto eziphilayo zitsale ingqalelo njengabantu abathembisayo kwii-elektroniki ezinxitywayo zesizukulwana esilandelayo kuba zinokudibanisa imisebenzi ye-transistor kunye ne-light-emitting diode kwisixhobo esinye.
Nangona kunjalo, ii-transistors zendalo eziqhelekileyo ezinesakhiwo se-electrode esecaleni zifuna ii-voltage eziphezulu zokusebenza ze-80 ukuya kwi-180 V ngenxa yomgama omde phakathi kwee-electrodes kunye nomqobo omkhulu we-electron-injection.
Nokuba kusetyenziswa i-electrochemical ion doping ukunciphisa i-voltage yokusebenza, kusafuneka ngaphezulu kwe-3.5 V, kwaye indawo yokukhupha umoya ihlala incinci kwaye ingazinzanga, nto leyo ethintela ukusetyenziswa okusebenzayo kwizibonisi zokwenyani nakwiinkqubo ze-elektroniki ezikrelekrele nezinxitywayo.
2.Indlela esebenza ngayo i-transistor entsha
Iqela lophando liphuhlise i-transistor ye-electrochemical organic ekhupha ukukhanya okuphantsi kakhulu edibanisa ukucubungula imiqondiso, inkumbulo kunye nokukhupha ukukhanya ngaphakathi kwe-transistor enye yendalo.
Ngokufaka isincedisi sokuthutha ii-ion kwi-active layer ukuze kukhuthazwe ukwakheka kwe-electric-double-layer kwi-interface ye-electrode, iqela lizise indlela entsha yokufaka i-electron ngempumelelo ngaphandle kokuxhomekeka kwi-voltage ephezulu okanye i-doping engazinzile esetyenziswa kwiindlela zesiqhelo.
Oku kwenze ukuba ukukhanya kukhutshwe nokuba kukwii-voltages <3.5 V, ezazikade zithathwa njengeziphantsi kakhulu ukuba zingasetyenziswa, ngelixa zigcina indawo ebanzi nezinzileyo yokukhupha.
Esi sixhobo sikwabonise iimpawu zokucubungula imiqondiso kunye nememori, kunye neempendulo eziqokelelana phantsi kweempawu eziphindaphindwayo kwaye zigcinwe ngokuhamba kwexesha, kwaye saboniswa ngakumbi kwinkqubo yokubonisa eguquguqukayo esetyenziswa ziibhetri ezimbini ze-1.5 V kuphela.
Olu phononongo lubonisa ukuba ukukhutshwa kokukhanya okuzinzileyo kunye nokusebenza okukrelekrele kunokufezekiswa ngaxeshanye nakwisakhiwo esilula esisebenzayo somaleko omnye, okwandisa kakhulu amandla ee-transistors zendalo kwizicelo ezinokunxitywa.
3. Impembelelo enokubakho kwizinto ezinxitywayo
Olu phononongo lubalulekile kuba ludibanisa ukucubungula imiqondiso, inkumbulo kunye nokukhutshwa kokukhanya kwisixhobo esinye, nto leyo enciphisa imida yeenkqubo ze-elektroniki eziqhelekileyo ezinxitywayo ezifuna ukuba kwenziwe kwaye kudityaniswe izinto ezininzi ezahlukeneyo.
Ngokukodwa, ngokubonisa iimpendulo eziqokelelweyo nezigcinayo kwizinto ezifakwayo, igxininisa amandla e-elektroniki yesizukulwana esilandelayo anokucubungula ulwazi aze abonise iziphumo ngoko nangoko ngokukhanya.
Nangona izixhobo eziqhelekileyo ezinxitywayo zenza kube nzima kubasebenzisi ukujonga imiqondiso elinganisiweyo ngexesha langempela ngelixa behamba, le teknoloji ibhekisa ekubekweni esweni ngexesha langempela kunye nokunikezelwa kolwazi ngoko nangoko.
Kulindeleke ukuba yandiselwe kwizicelo ezifana nokuvuselelwa, ukhathalelo lwezigulane olungxamisekileyo, ukujonga umthambo, izixhobo ze-elektroniki ezisebenza eluswini kunye nokhathalelo lwempilo olukrelekrele, kwaye ingasebenza njengobuchwepheshe obuphambili obuvumela amashishini anxulumene noko.
UNjingalwazi uTae-Woo Lee ubonakalise ukukhuphisana kophando olukhokelayo kwihlabathi liphela ngeempapasho ezilandelelanayo kwiSayensi neNdalo ngo-2026.
Lo msebenzi udlula izixhobo eziqhelekileyo ezikhupha ukukhanya ngokuhlanganisa ukukhutshwa kokukhanya, ukucubungula imiqondiso kunye nemisebenzi yememori kwisixhobo esinye se-semiconductor kwi-voltage ephantsi, nto leyo ebonisa indlela entsha yesizukulwana esilandelayo sezixhobo zombane ezinxitywayo ezikrelekrele.
UNjingalwazi uTae-Woo Lee, owayekhokela olu phando, uthe, "Lo msebenzi unentsingiselo ngakumbi kuba ubonisa ukuba yonke imisebenzi ingadibaniswa kwisixhobo esinye se-semiconductor, ngaphandle kwemfuneko yokwenza nokudibanisa iiyunithi zokucubungula, imemori, kunye nokubonisa ngokwahlukeneyo."
Wongeze wathi, "Ukuya phambili, siceba ukuphuhlisa obu buchwephesha bube yiplatifomu ye-semiconductor ekwisikhumba esebenza kulusu olukrelekrele lokwenziwa kunye nonyango olunxitywayo."
