From Bill Gawne at the Space Telescope Science Institute

Hi all.  Is there anyone out there in netland interested in
discussing IR detector materials?  I was thinking of InSb
Pt:Si, and HgCdTe in particular; but any lead chalcogenide
folks would be welcome too.

I'm interested in fundamental physics, crystallography,
and chemistry of the materials.  Also engineering involved
in producing detector arrays for both astronomical and
terrestrial applications.

Please e-mail or post replies to sci.materials.  Thanks,

-Bill

I'm interested, particularly in the preparation of these materials.  I'm a
crystal grower and would like to know what problems exist with the above
mentioned state-of-the-art materials.  Is their composition uniform enough?
Is the defect desity low enough? Is the available size large enough?  Do
they posses sensitivities high enough?

I'd be interested in hearing what experience others have had in using and
preparing these materials.
