    Material Properties of n‐Type β‐Ga2O3 Epilayers with In Situ Doping Grown on Sapphire by Metalorganic Chemical Vapor Deposition by Fu‐Gow Tarntair, Chih‐Yang Huang, Siddharth Rana, Kun‐Lin Lin, Shao‐Hui Hsu, Yu‐Cheng Kao, Singh Jitendra Pratap, Yi‐Che Chen, Niall Tumilty, Po‐Liang Liu, Ray‐Hua Horng

    Published 2025-01-01
    “…Abstract In this study, in situ, Si‐doped heteroepitaxial Ga2O3 layers are grown on c‐plane sapphire by metalorganic chemical vapor deposition. The X‐ray diffraction peaks of the doped Ga2O3 epilayers shows ß‐phase of Ga2O3 ,and full width at half maximum of Ga2O3 crystallinity is decreased at a Tetraethoxysilane (TEOS) molar flow rate of 2.23 × 10−7 mol min−1 but increased with higher flow rates. …”

    Spatially Resolved Cathodoluminescence in the Vicinity of Defects in the High-Efficiency InGaN/GaN Blue Light Emitting Diodes by Manh-Ha Doan, Jaejin Lee

    Published 2014-01-01
    “…In addition to the standard 447 nm blue emission from the InGaN/GaN multiple quantum wells, a high-energy shoulder is clearly observed in cathodoluminescence spectra of the high-efficiency InGaN/GaN blue light emitting diodes grown on sapphire substrates by metalorganic chemical vapor deposition. Monochromatic cathodoluminescence images of the samples measured at low temperature reveal a competition between the two emissions in the vicinity of the dislocations. …”

    Performance of InGaN Light-Emitting Diodes Fabricated on Patterned Sapphire Substrates with Modified Top-Tip Cone Shapes by Hsu-Hung Hsueh, Sin-Liang Ou, Chiao-Yang Cheng, Dong-Sing Wuu, Ray-Hua Horng

    Published 2014-01-01
    “…InGaN light-emitting diodes (LEDs) were fabricated on cone-shaped patterned sapphire substrates (PSSs) by using low-pressure metalorganic chemical vapor deposition. To enhance the crystal quality of the GaN epilayer and the optoelectronic performance of the LED device, the top-tip cone shapes of the PSSs were further modified using wet etching. …”
