QUESTION
Consider an LED made of In 1-x Ga x As y P 1-y . An empirical relation that gives the band gap energy in terms of x and y is found as: E g (x,y)...
Consider an LED made of In1-xGaxAsyP1-y. An empirical relation that gives the band gap energy in terms of x and y is found as:
Eg(x,y) =1.35 + 0.668x -1.17 y + 0.758 x2 + 0.18y2- 0.069xy - 0.322x2y + 0.33xy2 eV
Find the band gap energy and the peak emission wavelength of In0.74Ga0.26As0.56P0.44.
