Blue LEDS are made from In,Ga1-N semiconductors with a band gap in eV given by E, = 3.40 – 3.75x + x2 (b) Given that the wavelength of blue visible light is 470 nm, what would be the value of x necessary to make a blue LED? Note the solutions to the quadratic equation 0 = ax? + bx +c are given by -b +Vb2 – 4ac x = 2a
