Pyramid LED arrays on amorphous glass

The structures consisted of an array of nearly single-crystalline truncated pyramids of gallium nitride (GaN) on which further layers of indium gallium nitride (InGaN) multi-quantum wells, magnesium-doped p-GaN, polymer filling and indium tin oxide (ITO) were deposited.



The researchers see potential applications as including using the pyramids as pixels in displays such as for large-area inorganic LED televisions, concluding: “This method should provide a new and attractive tool for realizing ideal high-performance electroluminescence devices that demonstrate both low cost and high device performance, as well as scalability to large sizes.”
