An InGaAsP semiconductor laser operating at a wavelength of 1.3 x10-6m has a cavity (formed by its interfaces with the air) of length 300 x10-6m.

A 10 monolayers thick layer of Ag is deposited on Mo. The intensity of electrons emitted by the Ag and Mo can be measured separately. The ratio IAg/IMoi =100 for the deposited film. The mean free path of the electrons is 0.6 nm and the thickness of one layer is 0.18 nm. After heating the sample, the Ag layer has agglomerated in islands that cover a fraction q of the surface. Between the islands the Mo is “visible”. The intensity ratio after agglomeration is IAg/IMof = 1. Calculate the sensitivity of the electron spectroscopy technique for Ag with respect to Mo. I.e. how many electrons are emitted from one layer of Ag atoms compared to one layer of Mo atoms. And use this to determine what fraction of the surface is covered by islands?
Photoconductivity and speed Consider two p-type Si samples both doped with 1015 B atoms cm−3. Both have identical dimensions of length L (1 mm), width W (1 mm), and depth (thickness) D (0.1 mm). One sample, labeled A, has an electron lifetime of 1 μs whereas the other, labeled B, has an electron lifetime of 5 μs. a. At time t = 0, a laser light of wavelength 750 nm is switched on to illuminate the surface (L × W) of both the samples. The incident laser light intensity on both samples is 10 mW cm−2. At time t = 50 μs, the laser is switched off. Sketch the time evolution of the minority carrier concentration for both samples on the same axes. b.
