copper oxide

I see two references that seem to give conflicting information -- one claims that "copper oxide also conducts electricity"; while the other says that "oxidized copper is almost as bad as oxidized steel as an RF conductor".

Is this the right page to list the actual conductivity value of copper oxide? Or is there some other, more appropriate page? --76.209.28.222 (talk) 05:14, 11 February 2009 (UTC)[reply]

Copper oxide is a semiconductor. It was used in metal rectifiers. Biscuittin (talk) 18:00, 17 October 2012 (UTC)[reply]

Silicon

Resistivity of pure Si (rt) is 10⁵ Ohm*cm = 10³ Ohm*m. The value here is probably for doped Si. Beware, WEL and many other sources in chemical elements data references could be plain wrong. I have just started checking Si, and already Young modulus, sound speed and resistivity are off by a factor of >5. NIMSoffice (talk) 00:25, 1 May 2009 (UTC)[reply]

Insufficient information

The unit used in the tables is nΩm. Does this mean nano ohms per metre? If so, it should be nΩm^-1. Also, the cross-sectional area of the wire needs to be specified, otherwise the data is meaningless. Biscuittin (talk) 18:09, 17 October 2012 (UTC)[reply]

My mistake. I am confusing Electrical resistivity with electrical resistance. Biscuittin (talk) 20:36, 17 October 2012 (UTC)[reply]

[sic]?

I see [sic] several times in the data. What does it mean? That the phase or chemical name is misspelled? (It isn't) Or does it mean the numeric data value is wrong..in which case, if the correct one is known, why not just fix the error? --RProgrammer (talk) 14:02, 1 October 2017 (UTC)[reply]
