hello,
everyone, I am not in this filed. So I get a simple question. Besides field emission and thermionic emission, is there any other means to excite the eletron and get electron beam. Could anyone tell me some basic similar ways to excite the ion and photon?
Thanks.
thanks everyone
Perennial, your advice is helpful. I want to calculate the residual stress before deposition experiment, so is there any equations for that involving parameters, i.e. chamber geometry, pressue, without any experiment only pure theoretical calculation.
Thank you, Mapes.
It seems to be a really tough work. But is there any equation including the residual stress as a function of your mentioned parameters, i.e. chamber geometry, pressue. As I can't conduct the work without any theory support.
hi,
everyone, now I am trying to deposite some metal layers on micro-scale cantilever surface on the purpose of bending it under the residual stress caused by metal deposition. I read some literatures which mentioned and even gave the exact value of residual stress happened in both the...
