  • Publication number: 20250072164
    Abstract: A method for forming an indium gallium nitride quantum well structure is disclosed. The method includes forming a gallium nitride microdisk on a substrate, with the gallium nitride microdisk having an inverted pyramid form and an end face; and forming multiple quantum well layers on the end face, with each quantum well layer including an indium gallium nitride quantum well and a barrier layer. The indium gallium nitride quantum well is grown at a growth temperature adjusted using a trend equation within a temperature range of 480° C. to 810° C.

  • Publication number: 20030122276
    Abstract: A method for manufacturing a substrate strap for electrical elements has arts of preparing materials, mixing the materials with a mixer, pressing the mixed materials to a strap with a desired thickness, roller pressing the strap at a high temperature to a precious thickness, roller pressing the strap at a low temperature to set and defining holes in the strap with a punching machine. Accordingly, the molecules of the uncrystallized material can be connected between the crystals of the crystallized material so as to form multiple fibers in the strap, such that the substrate strap has an excellent structural strength.
