Researchers from Korea's Kookmin University in Seoul, led by Prof. Young Rag Do, have developed a novel top-down process to fabricate and isolate sub-micron GaN microLEDs. The process combines electrochemical etching and sonochemical separation of the etched porous layer to isolate the microLEDs.
The researchers have used the process to produce Au-coated GaN blue LEDs that offer an EQE of 6.21% (at 4.0 V) and a luminous efficacy of 1,070 cd/m2 (at 10.0 V). The LEDs themselves had a diameter of 750 nm, these are true sub-micon LEDs.
The researchers further investigated the electrochemical variables that affect the nanopore size, separation ratio, and emission characteristics of dot LEDs, as well as the effect of solvent type on ultrasonic separation using a sonochemical process.
mình có lần lướt đọc mấy trao đổi trên mạng شيخ روحاني thì thấy nhắc nên cũng tò mò mở ra xem thử cho biết. mình không tìm hiểu sâu chỉ xem qua trong thời gian ngắn để quan sát bố cục cách sắp xếp جلب الحبيب các mục và trình bày nội جلب الحبيب dung tổng thể. cảm giác là các phần được trình bày khá gọn, các hurentest berlin mục rõ ràng nên đọc lướt cũng không bị rối với mình như berlinintim vậy là đủ để nắm tin cơ bản rồi. جلب الحبيب
This is a solid step forward—getting 6.21% EQE at just 750nm is impressive for a top-down process. Excited to see where this goes for AR displays! Arrow Puzzle
The development of a top-down method to create high-efficiency sub-micron microLEDs is truly fascinating. I was particularly intrigued by the impressive EQE of 6. 21% achieved with these tiny LEDs. This innovation could really advance display technology and lighting solutions. As someone interested in tech advancements, it’s exciting to think about how such small components can lead to significant improvements in efficiency.

C'est fascinant de voir comment la méthode de fabrication utilisée permet d'atteindre une efficacité quantique externe de 6,21 % pour ces microLEDs sub-microniques. L'impact de l'etching électrochimique sur la taille des nanopores et les caractéristiques d'émission est un aspect essentiel à considérer pour de futures applications. Cela me rappelle l'importance de bien comprendre les variables lors du développement de nouveaux dispositifs optoélectroniques.

Colony Flow quickly became my go-to game while waiting in line. The five waiting slots rule is so simple but transforms every level into a sequencing puzzle. I’ve lost count of how many times I’ve gone back to replay levels with better strategies.
