2 EE2 - Semiconductor Devices 2012
The course aims:
(1) To review the operation of diodes and bipolar junction transistors.
(2) To extend knowledge on bipolar devices to include the influence of recombination.
(3) To investigate the physical mechanisms underlying the delays and speed limitations of the devices.
(4) To extract equivalent circuit models for the devices.
Objectives:
Students should be able to
(1) Explain qualitatively the mechanisms of electronic conduction in bipolar devices, and calculate relevant
quantities from given data.
(2) Calculate and explain DC current-voltage behaviour of diodes and BJTs, given their geometry and material
properties.
(3) Explain the influence of excess minority carrier recombination of the performance of the devices.
(4) Explain the large signal behaviour of the devices from the internal storage of charge.
Recommended textbooks
EE1 background knowledge on semiconductors and semiconductor devices is required. The EE1 course notes
can be found on blackboard.
It is strongly recommended that you read these notes in order to understand the basic principles of
semiconductor devices.
Solid State Electronic Devices, B.G. Streetman & S. K. Banerjee, Prentice Hall International Editions, 6th
ed. This is a more expensive book but the course is based on this book. It contains a lot more than what is
taught in the 1
st
and 2
nd
year.
“Microelectronic Devices”, K.D. Leaver, IC Press, 2nd ed. This is a compact and relatively inexpensive book
which covers all the essentials.
Note that in popular books such as Microelectronics circuits by Sedra & Smith some very brief descriptions
of semiconductor device operation can be found. Whilst previous two books are very physics oriented, this
book is more oriented towards the circuit engineer and thus might give additional insight.
There are plenty of copies available of all these books in the Central Library.
An interesting on-line text books can be found on:
