Antimonide-based compound semiconductors

At the lowest end of the power spectrum is ABCS. Here's a technology that can operate at only one tenth of a volt! It is possible to create low noise amps that dissipate only one milliwatt - using ABCS. The market for these? Space-based arrays, where power is limited to solar cells, and received power from earth is pretty-well attenuated to next to nothing. Don't look for ABCS applications where high linearity is a priority, voltage breakdown is very low.

Antimony is number 51 on the periodic chart, right below arsenic. This puts it in Group Five, so it has an extra electron and acts as a donor. Antimony's symbol is Sb.

ABCS foundry examples:

Teledyne (was Rockwell Scientific)

Hey Teledyne, how about sending us an I-V curve?
