Of Organic Materials
Conductivity s = enm
n: number of carriers; m: mobility of the carriers
Conductivity is controlled by the phthalocyanine ring.
The metal core does not interfere the conductivity.
(2) Is there any one dimensional conductor in principle?
(3) How a charge hop from one p array to another adjacent p array?
