TÍNH TOÁN ĐỊNH HƯỚNG CHẾ TẠO CẤU TRÚC UVLED CHO BƯỚC SÓNG PHÁT XẠ 330nm

High-efficiency Ultraviolet Light Emitting Diodes (UVLEDs) have attracted
great attention in recent decades due to their promising applications in many fields. Such solid-state light sources are expected to replace the traditional fluorescent and incandescent lamps from the viewpoint of energy saving. Furthermore, UVLED are useful for application in the medical and biochemical fields, and the purification of the environment. In this paper, we provide an overview of research developments of UVLED. We calculate the physical and optical properties for the structure of UVLED with 3 multi-quantum wells of iAl y Ga 1-y N barrier - iAl 0.15 Ga 0.85 N QW - iAl y Ga
1-y N barrier by the SiLENSe software. This UVLED isemitted the wavelength of 330nm for sterilization.
