What is the work function of Nichrome?

AI Thread Summary
The work function of nichrome varies between 5.1 and 8 eV, influenced by the surface cleanliness. A chemically clean surface, typically achieved through strong acid washing, is ideal for accurate measurements. Washing with isopropanol and dry air may improve cleanliness but does not meet the criteria for being chemically clean. The discussion highlights the importance of surface treatment in determining the work function. Overall, achieving a precise work function value requires careful consideration of the surface condition.

Hello,
Does anyone know the work function of nichrome ? I can't seem to find it online.

Thanks,

Hmmm. I found the following info, but I'm not sure it helps that much: http://lappddocs.uchicago.edu/documents/230/sendit
Depending on the cleanliness of the surface of the nichrome, work functions range from 5 to 8 eV.

Check the source to make sure it's what you actually need.

I had seen that but didn't notice what you pointed out. Any idea about very clean nichrome wire ?
Thanks.
 
Not sure, sorry.

Not specifically, but 'chemically clean' often means washed with a strong acid, such as nitric.

Hi,
Would washed with isopropanol and dry air count as clean ?

It would help, but probably not qualify as 'chemically clean.' There are too many things that alcohols do not dissolve.

Hopefully someone else can jump in here with more detailed answers. I'm an electronics guy and chemistry is just random stuff I've picked up along the way.
 
Hello,
I'm the opposite to you then, with chemistry as my main area ! Anyway, thanks for your help, it's been very useful.
Thanks,

The article says
The work function of Nichrome runs between 5.1 and 8 eV, depending on the cleanliness of the surface
