3 By completing the PN-Junction Lab in [[Resource(5065)]], you will be able to:
4
5 a) conduct drift-diffusion modeling,
6
7 b) describe the physical and mathematical operation of PN-Junctions, and
8
9 c) build and validate a simple PN Junction simulation tool.

18 == Recommended Reading ==
19
20 If you have not had experience with pn-junction physics and modeling, here is a list of resources that will help you have the required knowledge to get the most of these materials:
21
22 1. Rober F. Pierret, Semiconductor Device Fundamentals (Addison-Wesley Publishing Company, 2000). (theory of pn-diodes)
23
24 2. Michael Shur, Physics of Semiconductor Devices (Prentice Hall, 1990). (theory of pn-diodes)
25
26 3. Dragica Vasileska, Stephen M. Goodnick and G. Klimeck: Computational Electronics: Semiclassical and Quantum Device Modeling and Simulation, (CRC Press, 2010). (modeling of pn-diodes)

38 * [[Resource(9094)]] (physical, analytical model)
39
40 * [[Resource(8797)]] (simulation)
41
42 * [[Resource(9098)]] (computational model)

48 == Tool Verification ==
49
50 Verification of the pn-junction tool is done by comparison of the simulation results for the electric field in equilibrium with the depletion charge approximation results. This verification process can be done while running the tool only, as it superimposes the depletion charge approximation results.
