Light-emitting diode (LED) and micro LED substrates and methods for making the same
Micro LED displays offer brighter screens and wider color gamuts than that achievable using traditional LED or OLED displays. Various embodiments are directed to LED and micro LED structures having substrates comprising a metal and oxygen, such as gallium and oxygen, and methods of forming the same. An integrated circuit (IC) structure can include a substrate comprising a metal and oxygen and a core over the substrate. The core can include a group III semiconductor material and nitrogen, and the core can be doped with n-type or p-type dopants. An active layer comprising indium can be provide on a surface of the core. The indium concentration can be adjusted to tune a peak emission wavelength of the IC structure. The IC structure can include a cladding on a surface of the active layer. The cladding can be doped with dopants of opposite type than those used to dope the core.
