You might look into Constantan. These displayed good adhesion to flouride
crystals for me in grad school some years ago in phonon (heat pulse)
experiments. I applied 100-V, 10-ns pulses to these at 50-Ohms and they usually
held up (near 4.2-K).

Subject: [mems-talk] Thin film resistive heaters
Hello Everyone,
I am trying to pattern resistive heaters on a glass substrate. Au heaters
have been used with Cr as the adhesion metal layer on glass. However, we
noticed that at high temperature application the resistance of the Au
metal was unstable, resulting in varying temperature.
(1) Has any one tried a similar process and tested these heaters at
approximately 100 degree C. ?
(2) Any suggestions regarding which could be the other metals (and
adhesion layer) that could be used to pattern such heaters which would
have stable characteristics (of resistance) at approximately 100 C.
I would appreciate if anyone could take time off replying to my query.
Thanks.
Govind
