| Popis: |
Two types of conjugated molecular wires, biphenyldithiol (BPD) and 1,4-benezenedithiol (BDT), were introduced at the interface of NCF joints. The molecular wires could adsorb on the gold electrodes and improve the interface properties. Formation of electrical junction with molecular wires between Au electrodes could tune the effective work function (Φ) of Au electrodes. The lower work function reduced the tunnel resistivity and thus improving the electrical conduction significantly. The joint resistance of NCF with BDT and BPD was reduced by 1/3 and 2/3, respectively. The more distinct improvement with BPD was due to the higher thermal stability of BPD than BDT. Improvement of electrical performance of NCF enables the application of NCF in fine pitch and high performance interconnects in microelectronics. |
