Negative TCR materials

I'm on a search for negative temperature coefficient suitable UHV
material for electron amplification (gain) using high aspect ratio row
and column geometry; i.e., six micron pores on eight micron centers 390
microns thick. Searches to date with experimentation have used
semiconductors which are positive TCR. Present experiments use copper
oxide or silver sulphide. Any suggestions welcome.
Thank you,
