1. Semiconductors for which the minimum of the conduction band does not occur at the same wavevector as the maximum of the valence band, then they are known to have a smaller absorption coefficient that's why they are not used in light emitting devices.
2. Direct band semiconductors comes up in a design of multi junction solar cells. Solar cells have higher band semiconductors as we move deeper into wafer sothat they can absorb both low as well as high energy photons efficiently.
1. Explain why it is difficult to make light emitting devices out of indirect band gap...
Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 225 W/m2. If the polarization angle between the filters increases by 25° from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized.
Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 280 W/m2. 1) If the polarization angle between the filters increases by 25° from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized.

2. An unpolarized beam of light with intensity lo = 98.8 lux is incident on three ideal polarizing filters (lux = ). The axis of the first filter (filter A) makes an angle of 18° with the vertical and the axis of the second filter (filter B) makes an angle of 37° with the vertical. The third filter (filter C) is oriented so that its axis is horizontal. a. What is the intensity and polarization direction of the light after...

Unpolarized light passes through two polarizing filters. After passing through the first filter the intensity of the light (11) is 17 W/m2. The first filter is vertical (0 degrees), while the second filter is angled at 34 degrees. What is the new intensity of the light? If you have unpolarized light passing through two polarizing filters that are lined up to the same direction. How can you rotate them to block all light from passing through? rotate one by 45°...
