Recently we established a sintering approach, namely Cold Sintering Process (CSP), to densify ceramics and ceramic-polymer composites at extraordinarily low temperatures. In this work, the microstructures and semiconducting properties of V 2 O 5 ceramic and (1-x)V 2 O 5-xPEDOT:PSS composites cold sintered at 120 °C were investigated. The electrical conductivity (25 °C), activation energy (25 °C) and Seebeck coefficient (50 °C) of V 2 O 5 are 4.8×10-4 S/cm, 0.25 eV, and-990 μV/K, respectively. The conduction
