EGRE 303-electronic devices

This report should have continuous flow without any breaks or abrupt transitions! Everything included
in the report must serve a purpose! The report must reflect specifically what you learned in this lab project.
Use sections such as Introduction, Methods, Results and Discussion, and Conclusions.
Figures (schematics, simulation screenshots, etc.), tables, and equations (e.g. Fig. 1, Table 1, Eqn. 1) must be
consecutively numbered in the order they appear and must be properly cited in the text of the report (e.g. as
shown in Fig. 2 …, Table 1 tabulates …, According to Eqn. 3 …). All figures and tables must have captions.
References must be provided at the end of the document and all references must be cited properly within the
text. (Wikipedia is not acceptable)
Failure to satisfy these requirements will result in a lower grade.
Report Deliverables:
Introduction should overview the basics of PN junction devices including major features of their design and
typical applications.
For part 1, compile the results of your calculations:
List the equations used with a legible description of their purpose, specification of parameters, and values
of physical constants used (e.g. Boltzmann constant).
You are encouraged to use computer software for the calculations, when it is justified and possible.
For part 2, compile all the relevant the relevant simulation results: charge density, electric field, and
electrostatic potential as a function of position
Using the resulting plots, answer the following questions.
For the symmetrical (or nearly symmetrical) PN junction, problem 3 shows that the depletion approximation
works well, except for some small differences. For the asymmetrical PN junction, however, the depletion
approximation produces significant errors for the charge density and electric field. Use the plots to explain why
EGRE 303 Lab 3: PN Junction Lab
the depletion approximation fails for asymmetrical junctions. Why the depletion approximation breaks down so
obviously for the asymmetrical PN junction?
