Nitride nanowire light emitting diodes
2015 Edition, July 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Here we present our recent results on nitride nanowire light emitting diodes. In particular, we discuss the single wire light emitting diode fabrication and coupling of single nanowire emitters with waveguides in order to form a functional photonic...

Superconducting Light-Emitting Diodes
2015 Edition, Volume 21, March 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Cooper pairs form spin singlet states and are regarded as entangled electron pairs. Extracting entangled electrons has been actively studied by the use of superconductor-normal metal junctions. We have proposed to convert Cooper pairs to entangled photon pairs via interband radiative recombination...

Organic light emitting diodes
1996 Edition, January 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Organic light emitting diodes with a complex multilayer structure have been successfully fabricated for bright light emission in the entire visible spectral region. The CIE coordinates of the blue, green, and red emitting electroluminescent devices are plotted in...

Light-emitting diodes
1971 Edition, Volume 18, September 1, 1971 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper gives a brief review of the technology and performance of some of the currently interesting light-emitting diodes. Rather more attention is paid to gallium phosphide than to some of the other materials both because of its scientific interest and its potential...

Light-emitting diodes
1970 Edition, January 1, 1970 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

There is a growing interest in the development of devices that can efficiently convert electrical energy into light, particularly visible light. Of special interest is the possibility that such devices may be electrically and, hopefully, even physically compatible with existing...

Comparative performance evaluation and assessment of organic light emitting diodes and light emitting diodes
2016 Edition, October 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Organic Light Emitting Diodes (OLED) are solid state devices having a great potential for commercial and industrial lighting applications. They are flexible and have an added advantage of not containing any toxic materials and hence are highly sustainable. In this paper, a...
