▎ 摘　　要

Herein, nonsaturating negative magnetoresistance (NMR) in laser-induced graphene (LIG) is observed at all temperatures (300-10 K) for the first time to the best of our knowledge. Three-dimensional (3D) variable range hopping conduction is a dominant conduction mechanism in the as-grown and, 350 degrees C and 400 degrees C annealed specimens. Flexible and wearable magnetoelectronic devices are possible as LIG is fabricated on polyimide. (C) 2019 Elsevier B.V. All rights reserved.
