“…The higher the critical temperature T C of the base material, the thicker the layer of a normal metal is needed to suppress T C to the required values by the proximity effect. In this regard, the latest TES generations for operating temperatures of 30 to 50 mK are based on such materials as tungsten and iridium [ 8 , 9 , 10 ]. The values of their critical temperatures, 15 mK and 112 mK, respectively, are the closest to the required ones [ 11 , 12 , 13 , 14 ].…”

“…The iridium critical temperature can also be suppressed by the proximity effect [ 9 , 12 , 16 , 17 ]. But iridium is more expensive compared to hafnium, and the iridium technology is more complicated since it requires substrate heating and magnetron sputtering [ 8 , 10 ]. While tungsten has a critical temperature close to 15 mK [ 18 ], it has its drawbacks, such as several crystal modifications that can turn into each other during thermal cycles [ 13 ].…”

“…A superconductor such as iridium can also be used to accomplish the tasks set [10][11][12]. Iridium has superconducting properties close to hafnium; its critical temperature is 112 mK [10].…”

“…But there are difficulties with depositing iridium to the substrate; it is a more refractory and dense metal than hafnium. Therefore, it requires a magnetron sputtering machine and a heating of a substrate [10,12]. In addition, iridium is much more expensive compared to hafnium.…”
