"An extrinsic semiconductor is a semiconductor that has been doped.." What about extrinsic semiconductors that are insulators before they are doped e.g. boron doped diamond? That's a doped insulator, not a doped semiconductor. 82.46.3.220 ( talk) 13:32, 7 November 2010 (UTC)
And again "During doping, impurity atoms are introduced to an intrinsic semiconductor" This assumption is also made through most of the article. There is a lot to be fixed. 82.46.3.220 ( talk) 13:38, 7 November 2010 (UTC)
I guess then that it's too much to ask to use more informative images, like the one that has the silicon matrix with the dopeant (although i disagree with some of it, it needs to be redone with chemistry in mind) Charlieb000 ( talk) 07:44, 23 July 2014 (UTC)
For the P-type semiconductors the concept of " positive charge of the hole" needs to be rethought. Calling holes positively charged is a way to common miss-understanding of semiconductor function. The "hole" is the missing valance electron in the silicone crystal matrix due to boron only having 3 valance electrons. The net charge of the boron atom is 0 so slipping it into the silicon matrix does not create a positive charge. This "hole" will be a lower energy level for the extra electron from the N material to fall into, creating the negative charge in the P material at the PN interface and the plus charge in the N material when the electron jumps over and into the P valence hole. And this creation at the PN junction of a + charged N material and a - charged P material is the foundation of diode function, eg the depletion region. If the hole were in fact + then the electron would just cancel it to no net charge and there would be no diode and no semiconductors. CJr2d2 ( talk) 22:19, 3 March 2015 (UTC)
Suggestion: The table should also list type II-VI semiconductors like CdTe.
I suggest merging Extrinsic semiconductor and Intrinsic semiconductor. Both these articles are little more than stubs, and both articles are basically redundant; to explain one of these two complementary concepts requires explaining the other. Either article could be the target of the merger; but I think it might make more sense to merge both into a new article: Intrinsic and extrinsic semiconductor. What do you all think? -- Chetvorno TALK 03:12, 4 August 2018 (UTC)
Under p-type semiconductor here could mention A Super-Thin Element Offers 'Positive' Potential for Transparent Electronics ? beta-telluride. (or maybe it's more significant for transparent conducting oxide) - Rod57 ( talk) 17:40, 21 April 2021 (UTC)
