For those interested... if u know any seniors who has this
book:
A-level Physics by Roger Muncaster, Fourth Edition, first
published 1981, fourth edition in 1993, reprinted in 1995
It has both notes on semicon and lots of questions on
Semiconductors at the back of the book. Right now, I'm typing the
questions into a worksheet for my students... Not sure if I can
finish in time... And then maybe try to do some on ExamWorld
Example question for those who would want to try:
1) What is the difference between intrinsic and extrinsic
conduction in semiconductors? Explain the effect of an increase of
temperature on intrinsic conduction. How does this differ from the
effect of an increase in temperature on a metallic conductor?
2)
(a) Give a typical sketch of the energy bands or levels at which
electrons may reside in a pure semiconductor, such as
silicon.
(b) Use your sketch to explain briefly:
(i) electric conduction
in pure silicon due to holes and electrons,
(ii) the variation of
semiconductor resistivity with temperature.
Do try... maybe u can do and let me put on ExamWorld, so save me
the effort
