Figure 1: Electronic structures before and after K dosing for a 30 uc FeSe film on SrTiO 3. Figure 2: Superconducting gaps in K-dosed FeSe films with varied thicknesses and that of K-dosed FeSe 0.93 S ...
Figure 1 is typical of a high-speed digital signal. As most of you are aware, the signal is anything but “digital.” Careful characterization of individual signal parameters like rise, fall, high, low, ...
