摘要: According to a first-principles study of the transport properties of two thiolated anthracene-9, 10-diono molecules sandwiching ethyl, a new method to induce molecular low bias negative differential resistance with multi-peaks for strong n-or p-type molecules is proposed. The anthracene-9, 10-diono molecule shows strong n-type characteristics when in contact with Au and Ag electrodes via a thiolate. The multiple negative differential resistance effect originated from the molecule–electrode couple is different between Ag and Au electrodes …
