Unformatted text preview: Ga 1-x N composition to achieve this color? (Show your work) _____________________ (b) Sketch the band structure of the device (GaN/In x Ga 1-x N) layers placing the p-side on the left of your diagram. You need to show the Fermi level and a reasonably accurate estimation of the relative band gaps of the layers, taking into consideration the answer provided in (a). (c) Sketch the band structure of a device with the MQW layer replaced with AlN. Would it still emit light? __________________...
