Both p- and n-doping of MEH-PPV were observed in the cyclic voltammograms, The chronoamperometric and AC impedance results indicate that the p-doping of MEH-PPV was controlled by the linear diffusion of counterions.展开更多
DURING the 1993’s expedition to the northern Fildes Peninsula of the King George Island,Antarctica, dark grey fine-sand and sub-clay sediments were found in the Xishi Gully, 250
