[mems-talk] Wettability of EB evaporated Au surface

[Steven Yang]

Hi, all
Does anyone know what is the wettability of EB evaporated Au Surface?
Always treat it as hydrophobic, which means water contact anlge large
than 90degree. However, recently read a paper giving the data of
around 60 degree on smooth surface and 80 degree on rough surface.
Kind of confusing. So, it wil be appreciated if you have any
experiment data to share on water contact angle on EB evaporated gold
surface.

Thank you very much in advance!
Best regards,
Steven
