ACTIVE REGION INCLUDING NANODOTS (REFERRED TO ALSO AS QUANTUM DOTS) IN MATRIX CRYSTAL GROWN ON SI SUBSTRATE AND CONSTITUTED OF ZINCBLENDE (REFERRED TO ALSO AS CUBIC) ALYINXGA1-Y-XN CRYSTAL (Y≥0, X>0), AND LIGHT-EMITTING DEVICE (LED AND LD) OBTAINED USING SAME

摘要

[Problem] To provide the structure of a high-luminance light-emitting device (LED) or high-luminance LD. [Solution] The present invention provides an LED characterized by including both AlyInxGazN crystals (y≥0, x>0) as matrix crystals which retain a zincblende crystal structure and In dots which have a higher In concentration than the AlyInxGazN crystals (y≥0, x>0) as matrix crystals, the matrix crystals and the In dots having been disposed over a zincblende BP crystal layer formed on an Si substrate.
