a OM and SEM images of raw fibers, filler matrix-coated fibers, and CTFs. Each scale bar in microscopic image denotes 200 nm. b Cross-sectional SEM images of the CTF with EDS mapping for (i) C K, (ii) Ag L, (iii) In L, and (iv) Ga L series. Each scale bar in microscopic image denotes 50 nm. c Relative atomic distributions of the CTF obtained through XPS depth-profiling analyses. The XPS spectra of the CTF from surface to core levels correspond to d O 1 s, e Ga 2p3/2, and f Ag 3 d orbitals. g Diameter and h electrical conductivity of each fiber as functions of the CTAC process speed. i Strain-stress curves for each fiber. j Relative resistance changes of each fiber as a function of strain.
