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

The specific objectives of the PN-Junction Lab are:

== Recommended Reading ==

Users who are new to the physics of pn-junctions and their modeling should consult the following resources:

1. Rober F. Pierret. (1996). ''Semiconductor Device Fundamentals.'' 2nd ed. Reading, MA: Addison-Wesley. (Specifically on the theory of pn-diodes)

2. Michael Shur. (1990). ''Physics of Semiconductor Devices.'' Englewood Cliffs, NJ: Prentice Hall. (Specifically on theory of pn-diodes)

3. Dragica Vasileska, Stephen M. Goodnick and G. Klimeck. (2010). ''Computational Electronics: Semiclassical and Quantum Device Modeling and Simulation.'' Boca Raton, LA: CRC Press. (Specifically on the modeling of pn-diodes)

== Theoretical descriptions ==

* [[Resource(7224)]] (tutorial)

* [[Resource(9094)]] (physical, analytical model)

* [[Resource(8797)]] (simulation)

* [[Resource(9098)]] (computational model)

* [[Resource(9092)]] (implementation details and source code dissemination)

== Tool Verification ==

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 only while running the tool, as it superimposes the depletion charge approximation results.


== Examples ==

The following [[Resource(9096)]] are described in detail:

Example 1: Equilibrium PN-Junction

Example 2: PN-Junction Under Bias

Example 3: Non-Symmetric Junction

Example 4: Series Resistance
