Muraayadaha iyo qaybaha kale ee muraayadaha indhaha ayaa si caadi ah loo abuuray iyada oo loo marayo isticmaalka daahannada indhaha ama geeddi-socodka nadiifinta. Habka cilmi-baarayaasha, oo ay soo saareen koox uu hoggaaminayo Yuji Oki oo ka tirsan Jaamacadda Kysuhu oo kaashaneysa koox ka socota Jaamacadda North Carolina State University oo uu hoggaaminayo Michael Dickey, ayaa adeegsaday fal-celin kiimikaad oo koronto lagu kaxeeyo si ay ugu sameyso dusha sare milicsiga birta.

Kala beddelka u dhexeeya milicsiga iyo kala firdhinta gobollada waxaa lagu samayn karaa iyadoo keliya 1.4 V, qiyaastii isla danab loo isticmaalo in lagu iftiimiyo LED-ka caadiga ah, iyo heerkulka cimilada.

Cilmi baarayaashu waxay diyaariyeen dariiq si firfircoon loogu beddelo dusha sare ee biraha dareeraha ah ee u dhexeeya milicsiga (bidix iyo bidix midig kore) iyo gobollada firidhsan (midigta sare iyo bidixda bidix). Marka korantada la isticmaalo, falcelinta kiimikada ee la beddeli karo ayaa qiiqa biraha dareeraha ah, iyadoo la abuurayo xoqado ka dhigaya birta inay kala firidho Awood siinta Keisuke Nakakubo, Jaamacadda Kyushu.

"Mustaqbalka dhow, tikniyoolajiyadan waxaa loo isticmaali karaa in lagu abuuro qalab loogu talagalay madadaalo iyo muujinta farshaxanimada oo aan horay loo helin," ayuu yiri Oki. "Hormarin dheeri ah waxaa suurtagal ah in lagu balaariyo tikniyoolajiyaddan wax u shaqeeya sida daabacaadda 3D si loogu soo saaro optics koronto lagu xakameeyo oo laga sameeyay biraha dareeraha ah. Tani waxay u oggolaan kartaa optics-ka loo adeegsado aaladaha lagu baaro caafimaadka ee iftiinka ku shaqeeya in si fudud oo raqiis ah loogu been abuuro meelaha adduunka oo aan lahayn tas-hiilaad shaybaadh caafimaad

Shaqada, cilmi baarayaashu waxay abuureen barkad iyadoo la adeegsanayo kanaal qulqulaya. Kadib waxay isticmaaleen "habka riixitaanka" si ay u sameeyaan dusha sare ee indhaha iyagoo ku ridaya biraha dareeraha ku jira gallium-ka godka ama nuugaya. Nidaamkan waxaa loo isticmaalay in lagu abuuro sagxad, fidsan, ama dusha sare, mid kasta oo leh astaamo muuqaal oo kala duwan.

Laga soo bilaabo isticmaalka korontada, kooxdu waxay kicisay falcelin kiimikaad oo la beddeli karo, taas oo oksijiinta biraha dareeraha ah ee geeddi-socodka isbeddelaya xaddiga dareeraha si ay u abuurmaan xoqitaanno yaryar oo badan oo dusha sare ah, taas oo keenaysa iftiinka inuu kala firdho.

Marka korantada loo adeegsado jihada ka soo horjeedka, biraha dareeraha ah waxay ku noqdaan sideedii hore. Xiisadda dusha sare ee biraha dareeraha ah ayaa soo saareysa xoqitaanka, kuna soo celinaysa xaalad muraayad milicsi nadiif ah leh.

"Ujeedkeenu wuxuu ahaa inaan u adeegsano qiiqa si aan u bedelno xiisadda dusha sare iyo xoojinta dusha sare ee biraha dareeraha ah," ayuu yiri Oki. “Si kastaba ha noqotee, waxaan ogaanay in duruufaha qaarkood awgood ay iskood isu beddeli doonaan oo ay noqon doonaan meel dusha ka firidhsan. Halkii aan u tixgelin lahayn inay taasi tahay guuldaro, waxaan sii wanaajinay xaaladaha oo aan xaqiijinay ifafaalaha.

Tijaabooyinku waxay muujiyeen in beddelaadda korantada dusha ka ah -800 mV illaa +800 mV ay yareynayso xoogga iftiinka maadaama dusha sare laga beddelay milicsiga loona kala firdhiyey. Cabbiraadaha korantada ayaa shaaca ka qaaday in isbeddelka korantada ee 1.4 V uu ku filan yahay inuu abuuro falcelinno diimeed oo leh dib-u-soo-celin wanaagsan.

"Waxaan sidoo kale ogaanay in xaaladaha qaarkood dusha sare ee waxoogaa oksijiin ah oo wali ilaalin kara dusha sare ee milicsiga," ayuu yiri Oki. "Adoo xakameynaya tan, waxaa suurtagal ah in la abuuro xitaa meelo kala duwan oo muuqaal ah adoo adeegsanaya qaabkan oo horseedi kara codsiyada aaladaha horumarsan sida jajabka biochemical ama loo isticmaalo in lagu sameeyo walxaha indhaha ee 3D-daabaca.
