Üretim yöntemimiz, numunenin özellik boyutlarının ve alanlarının ölçeklenebilirliği ve çeşitli materyallerin kullanımı için daha da modifiye edilebilir. EBL&#39;yi kullanarak alt mikrometre çizgi genişliğinde ( Şekil 3a-3c ) bakır EMTE&#39;lerin başarıyla üretilmesi, LEED üretiminde, elektrod kaplama ve baskı aktarımı da dahil olmak üzere EMTE yapısının ve kilit basamaklarının güvenilir bir şekilde bir alt mikrometre aralığına ölçeklendirilebilece...

Dünya çapında, esnek / gerilebilir TE&#39;lerin imal edilmesi için gelecekte esnek / esnek olarak kullanılmak üzere, indiyum kalay oksit ve flor katkılı kalay oksit (FTO) filmleri gibi katı şeffaf iletken oksitler (TCO&#39;lar) için yer değiştirmeleri aramak için çalışmalar sürdürülmektedir. Gerilebilir optoelektronik cihazlar 1 . Bu yeni imalat yöntemleri ile yeni malzemeler gerektirir. Grafen 2 , iletken polimerler 3 , 4 , karbon nanotüpleri 5 ve rasgele metal nanotel ağları 6 , 7 , 8 , 9 , 10 , 11 gibi nanomalzemeler incelenmiş ve bunların esnek TE&#39;lerdeki yeteneklerini göstermiş ve Mevcut TCO tabanlı TE&#39;ler, Filmin kırılganlığı 12 , düşük kızıl ötesi transmitans 13 ve düşük bolluk 14 dahil . Bu potansiyeli bile olsa, sürekli bükülme altında bozulma olmadan yüksek elektriksel ve optik iletkenlik elde etmek zor. Bu çerçevede, normal metal kafesler 15 , 16 , 17 , 18 , 19 , 20 umut verici bir aday olarak gelişmekte ve isteğe bağlı olarak ayarlanabilen oldukça yüksek optik şeffaflık ve düşük sac direnci sağlamışlardır. Bununla birlikte, metal kafes tabanlı TE&#39;lerin yaygın kullanımı birçok zorluk yüzünden engellenmiştir. Birincisi, imalat sıklıkla metallerin pahalı, vakum bazlı çökelmesini içerir 16 , 17 , </sup&gt; 18 , 21 . İkincisi, kalınlık, ince film organik optoelektronik cihazlarda elektrikli kısa devre 22 , 23 , 24 , 25&#39;e neden olabilir. Üçüncüsü, alt tabaka yüzeyi ile zayıf yapışma zayıf esneklikle sonuçlanır 26 , 27 . Yukarıda belirtilen kısıtlamalar yeni metal örgü tabanlı TE yapıları ve bunların imalatı için ölçeklenebilir yaklaşımlar için bir talep yarattı. Bu çalışmada, bir polimer filmde tamamen gömülü bir metal örgü içeren esnek TE&#39;lerin yeni bir yapısı bildirilmektedir. Litografi, elektrodepozisyon ve baskı transferini birleştiren, yenilikçi, çözüm tabanlı ve düşük maliyetli imalat yaklaşımı da açıklanmaktadır. Örnek EMTE&#39;de 15k&#39;ye kadar FoM değerleri elde edilmiştir. Gömülü doğası gereğiEMTE, dikkat çekici kimyasal, mekanik ve çevresel stabilite gözlemlendi. Ayrıca, bu çalışmada oluşturulan çözüm ile işlenmiş üretim tekniği, önerilen EMTE&#39;lerin düşük maliyetli ve yüksek üretim kapasiteli üretimi için potansiyel olarak kullanılabilir. Bu üretim tekniği, daha ince metal örgü çizgi genişliklerine, daha geniş alanlara ve çeşitli metallere ölçeklenebilir.

scalable solution-processed fabrication strategy for high-performance, flexible, transparent electrodes with embedded metal mesh

Burada yazarlar, bir polimer filmin içine tamamen gömülmüş bir metal örgülü yeni bir şeffaf elektrot (TE) gömülü metal örgülü şeffaf elektrotu (EMTE) rapor ediyorlar. Bu yazıda ayrıca bu yeni TE için düşük maliyetli, vakum içermeyen bir imalat yöntemi sunulmuştur; Yaklaşım lithography, electroplating ve imprint transfer (LEIT) işlemlerini bir araya getiriyor. EMTE&#39;lerin gömülü doğası, organik elektronik cihaz üretimi için gerekli olan yüksek yüzey yumuşaklığı gibi birçok avantaj sunar; Büküm esnasında üstün mekanik stabilite; Kimyasallara ve neme karşı elverişli direnç; Ve plastik film ile güçlü yapışma. LEIT imalatı, vakum içermeyen metal biriktirme için bir elektroliz işlemi içerir ve endüstriyel seri üretim için uygundur. Ayrıca, LEIT yüksek bir en-boy oranı ( örn . Çizgi genişliğine) sahip metal örgü imalatına izin verir ve optik tr&#39;yi olumsuz bir şekilde kaybetmeden elektriksel iletkenliğini önemli ölçüde arttırır.ansmittance. Birden fazla levha direnci 1 Ω / sq ve transmitansları% 90&#39;dan fazla olan, esnek EMTE&#39;lerin birkaç prototipini sergiledik ve 1.5 x 10 4&#39;e kadar çok yüksek değerlere (FoM) yol açtı. Bu, en iyi değerler arasındadır. Yayınlanmış edebiyat.

Şekil 1 , EMTE örneklerinin şematik ve üretim akış şemasını göstermektedir. Şekil 1a&#39;da gösterildiği gibi, EMTE, bir polimer filmde tamamen gömülü bir metal örgüden oluşur. Izgaranın üst yüzü alt tabaka ile aynı seviyededir ve daha sonraki cihaz üretimi için genellikle düz bir platform gösterir. Üretim tekniği Şekil 1b - e&#39;de şematik olarak a?...

Scalable Solution-processed Fabrication Strategy for High-performance, Flexible, Transparent Electrodes with Embedded Metal Mesh

Bu protokol, tamamen gömülü, kalın metal örgülü, yüksek performanslı, esnek, şeffaf elektrotlar için çözüm bazlı bir üretim stratejisi tanımlamaktadır. Bu yöntemle üretilen esnek transparan elektrotlar, ultra düşük sac direnci, yüksek optik transmitans, eğilme sırasındaki mekanik stabilite, güçlü alt katman yapışması, yüzey pürüzlülüğü ve çevresel stabilite dahil olmak üzere en yüksek performansı gösteriyor.
