I want to know the answer to the following question:
By what year will% of all GaN LEDs be made with gallium-nitride-on-silicon wafers?
All the background I'm provided with is that "A new style of wafers composed of gallium-nitride-on-silicon (GaN-on-Si) is being used to produce white LEDs using 200-mm silicon wafers.". Is that enough to answer the question?
Answer: no
