The internally generated power within an LED (refractive index: 3.46) is 5 mW at a drive current of 70 mA. The external power efficiency of the device is 0.5 % at this drive current and the potential difference across the device is 1.8 V.

4.6.1 Determine the peak emission wavelength from the device when the radiative and nonradiative carrier recombination lifetimes in the active region are equal. (4)

4.6.2 Determine the transmission factor for the LED-air interface.

Banzhaf Power Index Consider 5 voters, labeled A, B, C, D, and E, who are shareholders on a company board. 1) If there are 11 votes total and a 2/3 majority is required to pass a motion, what is the quota? That is, how many votes are required to pass a motion? (Hint: the answer is a whole number between 0 and 11 that represents at least a 2/3 majority). 2) Suppose A has 5 votes, B has 3 votes,...
