Calculate the short-circuit current for a photodiode under uniform illumination of light intensity 100 w/cm2 . the light is monochromatic, and the photon energy is larger than eg. assume light is absorbed uniformly through the thickness (not physically correct, but a simplification we will apply nonetheless), and 1 out of 100 incident photons produces an electron/hole pair. the relevant dimensions of the diode are: total length between one ln and one lp from the transition region edge on the p side and n side, respectively, is 2 mm, and the width and height are both 1 cm. the lifetimes for both electrons and holes is 10 μs.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
