Fig. 5: Electrical properties and defect characterization of SC-1 and SC-2.

a The I-V curves of SC-1 and SC-2 (insert: single crystal I-V curve test device illustration, silver paste at both ends of the crystal). b Time-dependent I-V curves under UV treatment. c Time-dependent electrical conductivity under UV treatment from 2 to 14 min (insert: The conductivity of UV treatment showed a similar linear increase for 5–12 min). d temperature-dependent I–V curves of SC-1, variable temperature I-V curves of 298 K-353 K were depicted in Supplementary Fig. 42. e Arrhenius linear fitting of temperature change. f Electrochemical Impedance Spectroscopy of SC-1, 2. g, h EPR spectrum (black curve) and EPR simulation result (red curve) of SC-1, SC-2 and TCNB (pink line) at 2 K. Normalized ultralow temperature 2 K blue line weak signal at g = 2.0018. i PALS spectra of SC-1 and SC-2.
