3. The green excitation source, a Diode Pumped Solid State (DPSS) laser emitting at 532 nm with an output power of ~ 80 mW at 0.85 A is used to excite luminescence in AlInGaP. Can this be replaced by an Argon ion laser (514nm) with an output power of 5 mW, or a high-powered 0.5W GaAlAs laser diode at 815 nm? Explain.

3) A Particle Trapped in a Shallow Defect This is a simple model for a shallow trap or defect in a semiconductor, for example, or a more realistic model for a quantum dot. We are interested in the trap states, i.e., states where the particle is localized in the trap. Hence this requires E 0 dij(x) dx √x = - 1²/2 2 din(x) dx = For the odd solution, use the following solution with A' = - C': 4₁(x) = A' exx (x) = {₁(x) = B′ sin kx B' m(x)=C'e-xx III = din(x) dx You should also apply in each case the continuity conditions: 4₁ (x = -²2 ) = ₁ (x = -1) Pu (x=+) = m(x=+) dpm(x) dx |x=+12/2 VI 8 -- / x VI 212 x≤ - 1²/12 ≤x≤ 11/27 ≤ x |x=+23/23 Use these conditions in the solution to find a set of two homogeneous equations of two unknowns. Solve these equations to find a relation between k and K and plot the solutions on a graph.

2) A thin crystal of the metal oxide with a tetragonal crystal structure and lattice parameters a = 4.05 Å and c = 2.517 Å is tilted so that a 200 kV electron beam travels along the [001] zone axis. Create a schematic diagram of zero order Laue zone (ZOLZ) diffraction pattern for a crystals of thickness: a) 75 Å b) 400 Å You should assume there are no forbidden reflections and that the diffraction intensity drops to zero when the excitation error, s, exceeds the first minimum of the relrod. You should show the approximate number of beams in the ZOLZ circle. (10)
