Where to buy a pure semiconductor?

[Stanley514]

I do not know if this question relates to this division and would appreciate if it would be moved to proper division.

I want to buy a piece of fine, pure, highly doped semiconductor with dimensions approximately:
7 cm X 7 cm X 1 cm (2 in. X 2 in. X 1/2 in.) It supposed to be just fine and well polished piece of material without any electronic components. In which type of stores it is best to look for?
No online trade or stores please.

Here's a surplus silicon dealer. If you don't want to order online, you can hoof it to Mound, Texas:

Otherwise, try lab supply houses. No online trade, huh? Trying to evade the NSA or some kind of embargo?

cool ... I didn't know one could buy blank wafers ... I assumed it was all inhouse with chip manufacturers

haha that thought also went through my mind

BTW .. isn't pure and highly doped a bit of a contradiction ?

Yah. The operative word about the wafers was that they were 'surplus' to the chip makers needs.
