Abstract

The transport properties in molecule consisting of two phenyl-rings connected via Co and N atoms are investigated by first principles, where the molecule is put between two ZGNR electrodes. Rectification and spin filtering effects are found in our designed molecule. The current at positive biases is much bigger than that at negative biases for both the P and AP configurations, which results in rectification effect. In addition, the spin down current (the spin up current) is nearly depressed for the (anti) configuration, while the spin up current (the spin down current) owns comparable values. So spin filter can be achived. Detailed explanation via transmission spectra is given to the above useful phenomenon.
