The electron transport and electrical properties in a methanofullerene PCBM are investigated. It is demonstrated that the temperature dependent and thickness dependent current density versus voltage characteristics of PCBM devices can be accurately described by using the improved mobility model. In addition, the width of the Gaussian density of states of PCBM is significantly smaller than the values usually reported for conjugated polymers. Furthermore, it is shown that the variatio n of voltage with boundary carrier density is dependent on the current density. Both the maximum of carrier density and the minimum of electric field appear near the interface of devices..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
