Talk:List of semiconductor materials

IV-VI semiconductors

Correct me if I'm wrong, but the lead sulphide and telluride and selenide materials are in fact II-VI semiconductors.

Lead is group IV, and sulphur, selenium, tellurium are group VI in the periodic table.

Some elements have more than one oxidation state, but that doesn't change their periodic table group. Gah4 (talk) 06:09, 9 May 2023 (UTC)

Oxides

Why are the oxides not arranged in the same categories as other semiconductor compounds? e.g. Copper (I,II) Oxide is I-VI material. Jcb.h6t (talk) 18:42, 2 April 2010 (UTC)

Graphene

Shouldn't Graphene be included in this list? Graphene differs from most conventional three-dimensional materials. Intrinsic graphene is a semi-metal or zero-gap semiconductor. Wbm1058 (talk) 18:52, 2 December 2011 (UTC)

Indium Selenide

Recent discoveries have been made on this compound, which would probably allow it a spot on the list. — Preceding unsigned comment added by 93.211.36.145 (talk) 02:20, 24 November 2016 (UTC)

Proposed merge with Compound semiconductor

Talk:Compound semiconductor I ended up on this article after a customer sent in a materials data request that had the first paragragh as a direct quote. I was suspicious as there was a distinct difference between the language of the email and the quotation.

I am not sure why this article is here - the information that it supplies is already very well explained in http://en.wiki.x.io/wiki/List_of_semiconductor_materials and in http://en.wiki.x.io/wiki/Semiconductor.

Additionally the opening statement "A Compound Semiconductor is a semiconductor compound " is a circular reference as a definition and is misleading - a compound semiconductor can be understood to be a device made of several discrete elements ( E.G. - die stacking) and not necessarily a direct reference to the materials used in doping the wafer. 209.68.160.241 (talk) 17:49, 30 January 2012 (UTC)skysail  Senator2029 ➔ “Talk”  02:22, 24 August 2013 (UTC)

Mercury telluride HgTe

Mercury telluride HgTe is absent at table. But it is a semi-metal related to the II-VI group of semiconductor materials. Voproshatel (talk) 16:24, 1 March 2020 (UTC)

Error, when sorting via band gap

Sorting depends on number of digits instead of actual value, for ex. 0.9 < 0.17 or 0.95 < 0.726

Should be fixed now. Or at least close. Gah4 (talk) 06:07, 9 May 2023 (UTC)

I used this awk program:

 
BEGIN {
   FS="\\|\\|"
   OFS="||"
   }

/\|\|/ {
   gap = int($5*1000)
   $5 = "data-sort-value=\"" gap "\"|" $5
   print substr($5,1,50)
   gap = int($6*1000)
   $6 = "data-sort-value=\"" gap "\"|" $6
   print substr($6,1,50)
   }

{ 
   print  > "output.table"
}

Split non-list content

This article contains a significant amount of information about semiconductors, compound semiconductors and alloys which, in my opinion, would deserve their own article or to be part of the Semiconductor article. I think we should move the section about compound semiconductors to the Semiconductor article. This section was merged into this list from its own article in 2016 and appears to me to be too hidden in this list article.

People interested in learning about compound semiconductors should be directed either to a section of the Semiconductor article or to a stand-alone "compound semiconductor" article, but not to a long list article about semiconductors, compound or elemental. What is the general opinion on this?--ElMagyar (talk) 12:03, 27 September 2021 (UTC)

Seems to me that alloy semiconductors could have their own article. Especially as there are a large number of them. Gah4 (talk) 09:48, 8 August 2022 (UTC)

table should specify temperature for band gap

The table current just calls its 5th column as "Band gap (eV)", but doesn't the temperature really need to be specified? The ref for Silicon's gap being 1.12 V says that is for 300 Kelvins. But I haven't checked whether the other materials are also for 300 K or some other temperature.

I'm thinking maybe have two columns: one for 0K, and one for around room temperature. Em3rgent0rdr (talk) 01:12, 4 October 2023 (UTC)

It does change with temperature, but not all that fast. What does change is carrier concentration. Pretty much, at 0K they are insulators instead of semiconductors, so wouldn't be in this table. On the other hand, one of the complications with quantum computers is getting information in and out. As QC's need low temperature, transistors that can work at low, though not quite that low, temperature are needed. Gah4 (talk) 13:52, 4 October 2023 (UTC)

OK, it seems that silicon gets to 1.170eV at 0K as shown here. It seems, as shown, what they actually do is a quadratic fit. As noted in that one, there are two ranges. I suspect, but didn't check, that the band edges that define the gap change at that point. But okay, we could have such a column. Gah4 (talk) 14:04, 4 October 2023 (UTC)
