Organic LEDs: DNA benefits

The nucleic acid bases that form DNA can serve as a useful hole-transport (electron blocking) layer in organic light emitting diodes (OLEDs), according to scientists in the USA. Eliot Gomez and co-workers report that because adenine and thymine can be thermally evaporated, they can be easily incorporated into the fabrication of OLEDs made by vacuum deposition and offer efficient hole-transport ...

Measurement of Leds

Semiconducting Polymer LEDs

Technologies based on organic semiconductors may answer the increasing demands that consumers make in the areas of large-area electronics, lightweight displays, and portable computing. Advances in scientific understanding, technology, and device performance have occurred particularly rapidly in the area of polymer light-emitting diodes (LEDs). Material properties and economic considerations sug...

Impurity Influence on Nitride LEDs

Light emitting diodes (LEDs) are widely used nowadays. They are used in major parts of our life. But it is still necessary to improve their characteristics. In this paper the impurity and Indium atoms influence on the LEDs characteristics is investigated by computer simulation. Simulation was carried out in Sim Windows. The program was improved for this purpose by creating new files for AlGaInN...

Resonant Cavity Quantum Dot LEDs

Quantum dot LEDs (QD-LEDs), which capitalize on the excellent color saturation and high photoluminescence efficiencies offered by quantum dots, promise to be part of future generations of display technologies [1]. The goal of our project is to integrate the already developed technology of the QD-LED into a resonant cavity (RC) and thereby achieve enhanced, directed electroluminescence (EL) that...
