Behavior of charges in the active zone of composite OFET under the source-drain electric field

[摘要] Charge accumulation and relaxation processes in the OFET active zone are studied. It is found that positive and negative charges injection from metal electrodes under drift field occurs. Characteristic time of these processes is found to be about 30 sec. Behaviour of charges under the combination of source-drain and gate potentials is also investigated.
