a) Draw the energy levels (including the Fermi levels) of a non-degenerate p-n junction with a reverse bias of Vr. Draw the hole and electron concentrations as well. b) If this pn junction is used as a photodetector, what is the threshold wavelength of this detector? Will lower or higher wavelengths be detected by this detector?

(a) Describe the behaviour of positive and negative charges within a p-n junction. Use a sketch/sketches (drawn by hand) to support your description. (b) Show your knowledge and understanding of the actions involved with the following devices; (i) A diode (ii) A bipolar transistor (iii) A MOSFET (c) Use semiconductor theory to describe the movement of charge carriers in each of the three devices given in Task (b). (d) For each of the devices given in Task (b) make a...

Elasticity a. Use two diagrams (one for Alberta, one for the world) to explain why the following might be true: A drought around the world raises the total revenue that farmers received from the sale of grain, but a drought only in Albert reduces the total revenue that Alberta farmers receive. b. You have the following information about good X and good Y: • Income elasticity of demand for good X: -3 • Cross-price elasticity of demand for good X...

1. Use two diagrams (one for Alberta, one for the world) to explain why the following might be true: A drought around the world raises the total revenue that farmers received from the sale of grain, but a drought only in Alberta reduces the total revenue that Alberta farmers receive. 2. You have the following information about good X and good Y: • Income elasticity of demand for good X: -3• Cross-price elasticity of demand for good X with respect...
