I am using grids made of Cu for my in-situ heating experiments (from 400°C to 600°C). However, there is a huge Cu- contamination after the heating, which is due to Cu thermal evaporation at high temperatures. Is the any TEM FIB Lift-Out Grids that doesn't produce metal evaporation at high temperatures?
Hi Minh-Anh,
Why don't you go for free standing TEM lift-outs? Are you doing in-situ heating in the TEM? If yes, then you can ex-situ (using an optical microscope) or In-situ prepare your lamella and transfer it onto the MEMS based chips. That's one way to transfer a free-standing lamella.
Check the attached file!
Hello Minh-Anh,
FIB lift-out grids made of pure carbon (Carb-N-Grids, offered e.g. by plano-em) can be also used for your purpose.
Best regrads,
Andriy
Thank you everyone for your useful suggestions! @Praveen Kumar I am using the double tilt heating holder from Gatan, so MEMS chips cannot be used for this holder.
