Subject: Re: Homemade Hall Effect Sensor
Some instructions on making Hall measurements from a doped wafer are in the
1. Adrian C. Melisinos, "Experiments in Modern Physics", page 90, Academic
2. Daryl W. Preston, Eric R. Dietz, "The Art of Experimental Physics", page
312, John Wiley & Sons, 1991.
I hope that is what your are looking for. Many years ago, when I had to
make doped germanium samples, I used to follow the procedure from
Melisinos. The trickiest part is making the contacts to the doped wafer
If you could not find the books, please let me know. I could fax or email
information from those 3-4 pages. Jack
