Nitride-Based Asymmetric Two-Step Light-Emitting Diode With In$_{0.08}$Ga$_{0.92}$N Shallow Step

IEEE Photonics Technology Letters, 2009

A nitride-based asymmetric two-step light-emitting diode (LED) with In0.08Ga0.92N shallow step was proposed and fabricated. It was found that the low indium content In0.08Ga0.92N layer can significantly enhance phase separation and/or inhomogeneous indium distribution in the active In0.27Ga0.73N layer. It was also found that we can enhance LED output power by a factor of 2.27 by simply inserting an In0.08Ga0.92N ...

IEEE Photonics Journal, 2012

We demonstrate a color-tunable smart display system based on a micropixelated light-emitting diode $(\mu\hbox{LED})$ array made from one InGaN epitaxial structure with high (0.4) indium mole fraction. When integrated with custom complementary metal–oxide–semiconductor (CMOS) electronics and a CMOS driving board with a field-programmable gate array (FPGA) configuration, this $\mu\hbox{LED}$ device is computer controllable via a simple USB interface and is ...

  • CMOS-Controlled Color-Tunable Smart Display

    We demonstrate a color-tunable smart display system based on a micropixelated light-emitting diode $(\mu\hbox{LED})$ array made from one InGaN epitaxial structure with high (0.4) indium mole fraction. When integrated with custom complementary metal–oxide–semiconductor (CMOS) electronics and a CMOS driving board with a field-programmable gate array (FPGA) configuration, this $\mu\hbox{LED}$ device is computer controllable via a simple USB interface and is capable of delivering programmable dynamic images with emission colors changeable from red to green by tailoring the current densities applied to the $\mu\hbox{LED}$ pixels. The color tunability of this CMOS-controlled device is attributed to the competition between the screening of piezo-electric field and the band filling effect. Comparable brightness of the $\mu\hbox{LED}$ pixels emitting at different colors was achieved by adjusting the duty cycle. Further measurement suggests that this microdisplay system can also be used for high-speed visible light communications.

  • Efficiency improvement of the structure InGaN/GaN for solar cells applications

    In this work, we were interested about the study of modeling and simulation of a structure based on In1-xGaxN/GaN for photovoltaic applications. This ternary alloy who is an III-V semiconductor presents important characteristics especially its bandgap energy, thus the enhancement of the absorption of photons with wavelengths near to red. We had also studied a different parameters characterized the solar cell which served us to calculate the efficiency of photovoltaic conversion. For the In0.35Ga0.65N/GaN structure, we obtained efficiency around 23%. This study of structures allowed us to fabricate structures for solar cells based on multi-junction.

  • Effects of prestrained layers on piezoelectric field and indium incorporation in InGaN/GaN quantum wells

    We investigated the effects of prestrained layers on piezoelectric fields and indium incorporation in blue-emitting InGaN/GaN quantum wells by using reverse-biased electroreflectance spectroscopy. We compared two sets of samples, which have identical structures except an insertion of an additional UV quantum well at the bottom of the blue-quantum well. Indium composition of quantum wells with the additional layer is larger than in the wells without the added layer. In contrast, the magnitude of the piezoelectric fields in the quantum wells with the added well is smaller even with higher In composition. The result shows that the strain in the quantum well is partially released and can be controlled by the insertion of the prestrained layer underneath.

  • Numerical simulations of novel InGaN solar cells

    Finite element simulations of novel InGaN solar cells, requiring no p-type InGaN, were carried out using the commercial software package APSYS. Simulations show that efficient, compositionally graded p-GaN/n-InxGa1-xN solar cells can be achieved, provided the graded layer is confined within the depletion region. These compositionally graded solar cells can be used as the top cell in an InGaN/Si double-junction cell to achieve AM 1.5 efficiencies over 27% using realistic material parameters.

  • The effect of mole-fraction on power spectral density of single quantum well based InxGa1-xN/GaN blue light emitting diode

    A single quantum well Light Emitting Diode (LED) is designed from two different semiconductors and the main advantages of quantum well structure are high radiative efficiency, surface recombination etc. We have designed the device in order to observe the impact of mole fraction on power spectral density at different wave length by keeping the anode voltage fixed. A nearly lattice matched AlGaN-InGaN-GaN double hetero-structure semiconductor device has been simulated to get the maximum power spectral density at a particular wave length. For the anode voltage of 5V, at a mole fraction of x= 0.24 for Indium in InxGa1-xN, it is observed that a power spectral density of 9.31 W /cm-eV is obtained at a wave length of 452 nm. Observations were made for mole fraction varying from x=0.01 to 0.30.

  • Orange–Red Light-Emitting Diodes Based on a Prestrained InGaN–GaN Quantum-Well Epitaxy Structure

    The implementations of an orange and a red light-emitting diode (LED), which are fabricated with a prestrained InGaN-GaN quantum-well (QW) epitaxy structure, are demonstrated. The prestrain condition is created by growing a low-indium QW before the growth of five high-indium QWs. Without the prestrain condition, the five high-indium QWs of the same growth condition lead to green electroluminescence emission. With the prestrained growth, indium incorporation in the QWs grown after the low-indium one becomes higher and hence the orange-red LEDs can be fabricated for elongating the emission wavelength by more than 100 nm. Although the crystal quality and electrical properties of the orange-red LEDs may need to be improved, our results have shown the important effect of prestrained growth for elongating the LED wavelength
