Query: Devices for Thermal Conductivity Measurements of Electroplated Bi for
  X-ray TES Absorbers   Electroplated Bismuth (Bi) is commonly used in Transition-Edge Sensors (TESs)
for X-rays because of its high stopping power and low heat capacity.
Electroplated Bi is usually grown on top of another metal that acts as seed
layer, typically gold (Au), making it challenging to extrapolate its
thermoelectric properties. In this work, we present four-wire resistance
measurement structures that allow us to measure resistance as a function of
temperature of electroplated Bi independently of Au. The results show that the
thermal conductivity of the Bi at 3 K is high enough to guarantee the correct
thermalization of X-ray photons when used as an absorber for TESs.
