I saw that the graph of resistivity to temperature of alloys like nichrome is like so
Meaning that even at 0 K it has some resistivity just like copper :
I read some where "It is the residual resistivity due to defect scattering" Is this related to the defects that i studied in solid state chemistry about lattice defects.Can some body elaborate?
- An alloy is a mixture of metals and a temperature coefficient of resistivity comparable to metals then why is its graph more linear than metals.
- Is this because of the lattice structure of an alloy?
