Transmission and its relation on Current

[medeepak]

Hi

Is current anyay related to the values of transmission. like if it is directly proportional to value of transmission??

i measured the current carried by a small AGNR for different potential biases and plotted its transmission spectrum

then i removed an atom from the AGNR and then plotted its transmission spectrum

though the value of transmission had decreased in the second case, the current conducted at certain potential biases is like 8 times the current carried by the defectless structure.

can this thing be right??

i have attached the images of AGNR's i used

regards

The current obtained by integrating the transmission spectrum at a given bias voltage. The single vacancy in graphene sheet (or graphene nanoribbon) will induce the defect states  near the Fermi level, which will be the scattering center for the electron transport.   The effect of defect on the electron transport of graphene has been extensively studied in literature. Please do a literature survey for such topic by yourself.
