چکیده
Abstract In this study, the monolithic integration of LEDs with different emission colors (wavelengths 543, 573, and 597 nm) directional radiation profiles was demonstrated. InGaN/GaN nanocolumn arrays ordered in a triangular lattice were prepared side by side, changing diameter n-GaN ( D ). The periodic arrangement nanocolumns led to photonic crystal (PC) effect. band edge wavelength λ B ) InGaN bandgap controlled . By controlling closely at wavelength, PC effect provided beam from angles approximately ±30°.

Blue–green–red LEDs based on InGaN quantum dots grown by plasma-assisted molecular beam epitaxy
Self-assembled InGaN quantum dots were grown in the Stranski–Krastanov mode by plasma-assisted molecular beam epitaxy. The average dot height, diameter and density are 3 nm, 30 nm and 7 × 1010 cm–2, respectively. The dot density was found to decrease as the growth temperature increases. The cathodoluminescence emission peak of the InGaN/GaN multiple layer quantum dots (MQDs) was found to red sh...
متن کاملPeriodically arranged GaN nanocolumns for the application to visible nanocolumn emitters
The selective area growth (SAG) of GaN nanocolumns with the diameter less than 100 nm was carried out on GaN/sapphire templates through a careful initial nucleation process of nanocolumns at the mask opening. We got the success of the fabrication of orderly arrayed fine nanocolumns down to the diameter of 25 nm, as shown in Fig. 1, where the nanocolumn period was 100 nm. The growth of highly un...

In this paper, five-period InGaN/GaN multiple quantum well green light-emitting diodes (LEDs) were grown by metal organic chemical vapor deposition with 405-nm light beam in situ monitoring system. Based on the signal of 405-nm in situ monitoring system, the related information of growth rate, indium composition and interfacial quality of each InGaN/GaN QW were obtained, and thus, the growth co...
متن کاملColor-saturated green-emitting QD-LEDs.
Semiconductor nanocrystals (NCs) or quantum dots (QDs) show great promise for use in QD-LED (quantum dot lightemitting device) displays, owing to their unique optical properties and the continual development of new core and core–shell structures to meet specific color needs. This in combination with the recent development of more efficient and saturated QD-LEDs as well as new QD-LED fabrication...

In this study, we report the concerted fabrication process, which is easy to transform the size of active emitting area and produce polarized surface light, using the electric-field-assisted assembly for horizontally assembled many tiny nanorod LEDs between two metal electrodes. We fabricate the millions of individually separated 1D nanorod LEDs from 2D nanorod arrays using nanosphere lithograp...
