Effect of Geometry, Joule Heating, and Critical Current on the Responsivity of MOD Superconducting Transition Edge Sensors

Three-dimensional analysis of bolometers responsivity using Green functions

“…The numerical results of this work are comparable to the previous experimental work in which an array of bolometer with different track widths is fabricated [15]. The results of ref.…”

“…The results of ref. [15] show that the responsivity increases by increasing the meander width except for the 40 μm case (fig. 5 of ref.…”

“…Generally, a superconducting bolometer for infrared radiation consists of thin-film meanders of a superconducting material on an insulating substrate which is attached to a heat sink [13]. Many works have been focused on the response optimization of this type of detectors both theoretically and experimentally [14][15][16][17][18]. Due to the improvement of thin-film fabrication techniques, the low-cost large-scale fabrication method is now available and therefore the structural optimization of the sensor plays an important role during fabrication [15][16][17][18][19].…”
