[mems-talk] Electrochemical setup for Porous silicon

[LSujatha]

Dear Narasimhan,
You can make the set-up by yourself. Buy a Teflon block of 5 or 7cm dia then 
cut it into the height approx. 12cm. Make it hollow with the inner dia of 2cm 
and make 6 holes for screws (3mm).

Make a groove to place o-ring.

Buy a stainless steel of same 7cm dia and make holes for threading screws 
matching with the holes on teflon. Buy screws and nuts.

You should have a Platinum mesh for cathode.


Refer Lehmann's paper.

With best wishes,
Sujatha
