TL;DR: In this paper, the fundamental properties of InGaN materials, such as optical, structural, and electrical properties, are reviewed, and the erroneous measurements of the indium composition by using X-ray diffraction (XRD) are also described.

TL;DR: The LED structures from the basic pn homoj junction, to heterojunction, and eventually the use of nano-scale low-dimensional structures in the device fabrication are described, and the conventional and innovative ways of producing white LEDs are briefly discussed.

TL;DR: The Burstein-Moss shift and band gap narrowing of sputtered indium-doped zinc oxide (IZO) thin films are investigated as a function of carrier concentrations, and the c lattice constant as well as film stress is observed to increase in stages with increasing carrier concentration.

TL;DR: In this paper, the effect of the Tauc plot scale and bandgap extrapolation technique on estimated optical bandgap values is often not strongly emphasized; however, it is observed that the proper extrapolation method for bandgap estimation is more appropriate as compared to the values obtained from the traditional direct extrapolation.

TL;DR: In this article, the effect of thin and uniform TiO 2 coatings within TiO2 nanotube layers for photocurrent generation and photocatalytical degradation of methylene blue are demonstrated for the first time.
