Ancak bu yeni nesil LED\u2019ler, sunduklar\u0131 potansiyelin yan\u0131nda ciddi verimlilik sorunlar\u0131n\u0131 da beraberinde getiriyor. <\/figure>\n

500 nanometrenin alt\u0131na inildi<\/b><\/p>\n

\u0130sve\u00e7 merkezli giri\u015fim Polar Light Technologies<\/strong>, Ocak ay\u0131nda 500 nanometreden daha k\u00fc\u00e7\u00fck prototip mavi LED\u2019lerini tan\u0131tarak sekt\u00f6rde dikkat \u00e7ekti. Geleneksel microLED teknolojisinde pikseller mikrometre seviyesinde \u00fcretilirken \u015firket, LED\u2019lerin nanoskopik boyutlara ula\u015fabilece\u011fini g\u00f6sterdi.<\/p>\n

\u015eirket, LED \u00fcretiminde yayg\u0131n olarak kullan\u0131lan galyum nitr\u00fcr<\/strong> (GaN) ve indiyum galyum<\/strong> nitr\u00fcr<\/strong> (InGaN) tabanl\u0131 yar\u0131 iletken malzemeleri kullanmaya devam ediyor. Ancak \u00fcretim y\u00f6ntemi geleneksel s\u00fcre\u00e7lerden ayr\u0131l\u0131yor. Standart LED \u00fcretiminde yar\u0131 iletken yap\u0131 yukar\u0131dan a\u015fa\u011f\u0131ya do\u011fru oyularak olu\u015fturulurken Polar Light, alt tabandan ba\u015flayarak alt\u0131gen piramit formunda<\/strong> b\u00fcy\u00fct\u00fclen bir yap\u0131 kullan\u0131yor. Bu yakla\u015f\u0131m, hem boyut k\u00fc\u00e7\u00fcltme hem de \u00fcretim kontrol\u00fc a\u00e7\u0131s\u0131ndan \u00f6nemli avantajlar sunuyor.<\/p>\n

\u015eirket, aslen microLED pazar\u0131na y\u00f6nelik geli\u015ftirilen bu piramit yap\u0131l\u0131 LED\u2019leri 2026 sonlar\u0131nda ticari \u00fcretime<\/strong> ta\u015f\u0131may\u0131 planl\u0131yor. \u015eu ana kadar 300 nanometre geni\u015fli\u011fe kadar<\/strong> k\u00fc\u00e7\u00fclt\u00fclen LED piramitlerinin teorik s\u0131n\u0131r\u0131na ise hen\u00fcz ula\u015f\u0131lm\u0131\u015f de\u011fil.<\/p>\n

Hedef daha da k\u00fc\u00e7\u00fclmek<\/b><\/p>\n

NanoLED alan\u0131ndaki geli\u015fmeler yaln\u0131zca Polar Light ile s\u0131n\u0131rl\u0131 de\u011fil. \u0130svi\u00e7re\u2019deki ETH Zurich<\/strong> ara\u015ft\u0131rmac\u0131lar\u0131, organik yar\u0131 iletken tabanl\u0131 OLED<\/strong> teknolojisini kullanarak \u00e7ok daha k\u00fc\u00e7\u00fck pikseller \u00fcretmeyi ba\u015fard\u0131. Elektron demeti litografisi y\u00f6ntemiyle geli\u015ftirilen ye\u015fil OLED dizilerinde piksel boyutu 100 nanometre seviyesine kadar indirildi<\/strong>.<\/p>\n

<\/span> Bu \u00f6l\u00e7ekte geli\u015ftirilen nanoOLED<\/strong> paneller, piksel yo\u011funlu\u011fu a\u00e7\u0131s\u0131ndan dikkat \u00e7ekici sonu\u00e7lar ortaya koyuyor. G\u00fcn\u00fcm\u00fczde en geli\u015fmi\u015f ekranlar in\u00e7 ba\u015f\u0131na yakla\u015f\u0131k 14.000 piksel yo\u011funlu\u011fa<\/strong> ula\u015fabilirken yeni nanoLED<\/strong> prototipleri teorik olarak 100.000 piksel\/in\u00e7<\/strong> de\u011ferine eri\u015febiliyor. <\/figure>\n

Bu yo\u011funluk, art\u0131r\u0131lm\u0131\u015f ger\u00e7eklik ve sanal ger\u00e7eklik uygulamalar\u0131 i\u00e7in yepyeni olas\u0131l\u0131klar anlam\u0131na geliyor.<\/p>\n

Benzer bir \u00e7al\u0131\u015fma \u00c7in\u2019deki Zhejiang University<\/strong> ara\u015ft\u0131rmac\u0131lar\u0131 taraf\u0131ndan ger\u00e7ekle\u015ftirildi. Bu ekip, y\u00fcksek verimli g\u00fcne\u015f panellerinde de kullan\u0131lan perovskit<\/strong> malzemelerini LED \u00fcretiminde kullanarak farkl\u0131 bir yakla\u015f\u0131m benimsedi. Ara\u015ft\u0131rmac\u0131lar, y\u00fczlerce mikrometre b\u00fcy\u00fckl\u00fc\u011f\u00fcnde ba\u015flayan LED piksellerini kademeli olarak k\u00fc\u00e7\u00fclterek 1 mikrometre s\u0131n\u0131r\u0131n\u0131 a\u015ft\u0131 ve sonunda 90 nanometre seviyesine<\/strong> kadar inmeyi ba\u015fard\u0131. Bu de\u011fer, g\u00fcn\u00fcm\u00fczde raporlanan en k\u00fc\u00e7\u00fck LED piksel boyutlar\u0131ndan biri olarak kabul ediliyor.<\/p>\n

En b\u00fcy\u00fck sorun verimlilik<\/b><\/p>\n

NanoLED teknolojisinin \u00f6n\u00fcndeki en b\u00fcy\u00fck zorluk ise boyut k\u00fc\u00e7\u00fcld\u00fck\u00e7e verimlili\u011fin d\u00fc\u015fmesi.<\/strong> Perovskit tabanl\u0131 nanoLED\u2019lerde harici kuantum verimlili\u011fi, yani enjekte edilen elektronlar\u0131n fotona d\u00f6n\u00fc\u015fme oran\u0131, yakla\u015f\u0131k y\u00fczde 5 ile y\u00fczde 10 aras\u0131nda de\u011fi\u015fiyor. Organik nanoOLED prototiplerinde bu oran y\u00fczde 13 seviyesine kadar \u00e7\u0131kabiliyor.<\/p>\n

Buna kar\u015f\u0131l\u0131k, milimetre \u00f6l\u00e7e\u011findeki geleneksel III-V LED\u2019ler renk t\u00fcr\u00fcne ba\u011fl\u0131 olarak y\u00fczde 50 ila y\u00fczde 70 verimlilik seviyesine ula\u015fabiliyor. Ara\u015ft\u0131rmac\u0131lar, \u00fcretim s\u00fcre\u00e7lerinin optimize edilmesi ve malzeme m\u00fchendisli\u011fi sayesinde nanoLED verimlili\u011finin gelecekte art\u0131r\u0131labilece\u011fini d\u00fc\u015f\u00fcn\u00fcyor<\/strong>. OLED tabanl\u0131 \u00e7\u00f6z\u00fcmlerde teorik olarak y\u00fczde 30 ila y\u00fczde 40 seviyelerine ula\u015f\u0131labilece\u011fi \u00f6ng\u00f6r\u00fcl\u00fcyor.<\/p>\n

Nelerde kullan\u0131lacaklar?<\/b><\/p>\n

NanoLED teknolojisinin geli\u015ftirilmesinin arkas\u0131ndaki en b\u00fcy\u00fck motivasyonlardan biri, ak\u0131ll\u0131 g\u00f6zl\u00fckler<\/strong> ve sanal ger\u00e7eklik<\/strong> cihazlar\u0131nda daha k\u00fc\u00e7\u00fck, daha keskin ve daha d\u00fc\u015f\u00fck enerji t\u00fcketimli ekranlar olu\u015fturmak. G\u00fcn\u00fcm\u00fczde ak\u0131ll\u0131 g\u00f6zl\u00fck \u00fcreticileri yakla\u015f\u0131k 3 mikrometre boyutunda piksel hedefleri belirlemi\u015f durumda.<\/p>\n

Ancak ara\u015ft\u0131rmac\u0131lar, sanal ger\u00e7eklik ekranlar\u0131nda piksel boyutunun yakla\u015f\u0131k 1 mikrometrenin alt\u0131na d\u00fc\u015fmesinin pratik fayda sa\u011flamayabilece\u011fini d\u00fc\u015f\u00fcn\u00fcyor. Bunun nedeni, \u0131\u015f\u0131\u011f\u0131n k\u0131r\u0131n\u0131m s\u0131n\u0131r\u0131n\u0131n a\u015f\u0131lmas\u0131 durumunda insan g\u00f6z\u00fcn\u00fcn daha k\u00fc\u00e7\u00fck pikselleri ay\u0131rt edememesi.<\/p>\n

<\/span> NanoLED\u2019lerin as\u0131l devrim yaratabilece\u011fi alanlardan biri ise yonga i\u00e7i fotonik sistemler<\/strong> olabilir. Bu teknoloji, \u00f6zellikle yapay zeka veri merkezlerinde veri ileti\u015fim h\u0131z\u0131n\u0131 \u00f6nemli \u00f6l\u00e7\u00fcde art\u0131rma potansiyeline sahip. D\u00fcnyan\u0131n en b\u00fcy\u00fck yar\u0131 iletken \u00fcreticilerinden biri olan TSMC, microLED tabanl\u0131 \u00e7ip i\u00e7i ba\u011flant\u0131lar<\/strong> \u00fczerinde halihaz\u0131rda \u00e7al\u0131\u015fmalar y\u00fcr\u00fct\u00fcyor. Uzmanlar, ilerleyen d\u00f6nemde daha k\u00fc\u00e7\u00fck nanoLED \u00e7\u00f6z\u00fcmlerinin bu alanda kullan\u0131labilece\u011fini de\u011ferlendiriyor. <\/figure>\n

NanoLED\u2019lerin dalga boyundan daha k\u00fc\u00e7\u00fck boyutlara ula\u015fmas\u0131, yaln\u0131zca ekran teknolojilerinde de\u011fil, optik m\u00fchendisli\u011fi<\/strong> alan\u0131nda da yeni f\u0131rsatlar yarat\u0131yor. Ara\u015ft\u0131rmac\u0131lar, bu piksellerin metay\u00fczey<\/strong> ad\u0131 verilen yap\u0131lar olu\u015fturabilece\u011fini g\u00f6sterdi. Bu yap\u0131lar, her pikselin kom\u015fular\u0131yla etkile\u015fimini kontrol ederek \u0131\u015f\u0131\u011f\u0131n davran\u0131\u015f\u0131n\u0131 hassas \u015fekilde y\u00f6nlendirebiliyor.<\/p>\n

Gelecekte bu t\u00fcr nanoLED dizilerinin lazer benzeri \u0131\u015f\u0131k demetleri \u00fcretmesi, holografik \u00fc\u00e7 boyutlu ekranlar\u0131n geli\u015ftirilmesi veya yeni nesil optik ileti\u015fim sistemlerinde kullan\u0131lmas\u0131 m\u00fcmk\u00fcn g\u00f6r\u00fcl\u00fcyor. Mevcut \u00e7al\u0131\u015fmalar hen\u00fcz erken a\u015famada olsa da nanoLED teknolojisi ekran ve fotonik d\u00fcnyas\u0131nda k\u00f6kl\u00fc de\u011fi\u015fimlerin habercisi olarak de\u011ferlendiriliyor.<\/p>\n\n
