Efrös and shklovskii variable range hopping (ES-VRH) conduction mechanism 0.5 0 0 ( ) exp ( / ) R T R T T is observed in the multiwall carbon nanotube (MWNTs) solid embedded in polymer poly(3,4éthylènedioxythiophène) polymerized with poly(styrène sulfonate de sodium) PEDOT-PSS at high temperatures, The presence of quasi-one-dimensional (MWNTs) helps in lowering the tunnel barriers at low temperatures, which explains the large negative magnetoresistance (MR) in this temperature interval. .
