This assumes thermal expansion coefficients have been fixed. Some thermocouple materials currently aren't usable due to incorrect thermal expansion values, and haven't been included on this list for now.

All values were empirically obtained on the ingame RTG designer, and might be off by about 1~2% on materials with high temperature deltas.

Aluminum: 13 K
Bismuth: 224 K
Cadmium: 42 K
Copper: 16 K
Gold: 185 K
Iron: 20 K
Lead: 13 K
Molybdenum: 347 K
Nickel: 130 K
Platinum: 125 K
Silver: 34 K
Tantalum: ~~132~~ 533 K
Tungsten: 510 K

Amorphous Carbon: 148 K
Diamond: 1456 K
Graphite: 2361 K
Pyrolytic Carbon: 1040 K
Selenium: 810 K
Silicon: 225 K

Sodium: 13 K

Constantan: 30 K
Nickel Chromium Cobalt: 251 K
Nickel Chromium Iron: 746 K
Platinum Molybdenum: 99 K
Tungstenium Rhenium: 310 K

Uranium Dioxides: 75 K

The value in that table may be off.

Pretty sure this is actually modelled. The very highly resistive ones (looking at you diamond) simply don't offer any reasonable efficiency.
