# Clarification on the Seebeck Effect

Alright, I've been interested in the Seebeck effect lately, so I've been trying to learn it. From what I understand, this is measured with the Seebeck Coefficient, which gives you the $\mu\textrm{V}$ (Millionth of a volt) per $\textrm{K}$ (Kelvin). For example (according to this), if I take Molybdenum and Nickel, with 1 Kelvin of difference, I will produce 25 $\mu\textrm{V}$.

This is where I need clarification, is this per contact (of any size)?

I'd assume that size DOES matter, at which point I'd ask, what unit of surface area is this in? (ex: $\mu\textrm{V}/\textrm{K}/\text{cm}^2$)

The only reason why I'd think that it is per contact, is that I can't find any unit of surface area.
