What is the work function of Nichrome?

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

Ok, thanks.
