Photoluminescence Spectroscopy
... In this experiment, the energy levels in a semiconductor quantum well structure are investigated using the technique of photoluminescence (PL). A laser is used to photoexcite electrons in a GaAs semiconductor and when they spontaneously de-excite they emit luminescence. The luminescence is analyzed ...

... Another equation for working kinetics problems involving particles can be derived by integrating the equation of motion (F = ma) with respect to displacement. By substituting at = v (dv/ds) into Ft = mat, the result is integrated to yield an equation known as the principle of work and energy. This p ...

... 11) Configure two timers to the correct height so that they measure the time it takes a glider to pass. The timers should be set to “gate” and “memory on”. 12) Shove one or both of the gliders so that they collide. If they collide with their Velcro sides, then it will be an inelastic collision. If ...
