Regulation and mechanism of graphene electrode bending on negative differential resistance of 2-phenylpyridine molecular devices

Acta Physica Sinica, 2023
Combining non-equilibrium Green’s function with density functional theory, we study the electronic transport properties of the molecular devices comprised of 2-phenylpyridine and zigzag graphene nanoribbon (ZGNR) electrodes. The <i>I-V</i> characteristics and transmission coefficients under external voltage biases are analyzed, and the ...
