ive never heard of this increasing work function

always thought it was constant for a given material

so just guessing

actually i thought...

Energy required to knock out an electron is work function.. but if due to increase of temp.. electron initially has some energy then less energy will be needed...

Edited above ... should decrease with increase in temperature..
