Recently, the Samsung Advanced Institute of Technology and Seoul National University have made an announcement that the first LEDs to be fabricated on amorphous glass substrates. As we know, manufacturers may peffer to improve GaN LEDs on silicon substrates (GaN-on-Si) rather than to choose gallium nitride (GaN)-based LEDs grown on crystalline sapphire wafers due to their expensive cost and are not amenable to large-sized wafer arrays. But the research conducted by the Samsung Advanced Institute of Technology and Seoul National University has found that...
