2014年10月1日 · In this study, we developed thin film of Fe (TCNQ) x∼2, other variation of organic-based magnetic thin film, which displays semiconducting behavior with room temperature conductivity σ ∼ 8.5 × 10 2 S/cm. The IR and photoemission spectra display the coordination between metal ion and TCNQ based on the charge transfer rather than a physical mixture.

We exposed a TCNQ thin film stepwise to sodium vapour and monitored the electronic structure by X-ray photoelectron spectroscopy (XPS) and ultra-violet photoelectron spectroscopy (UPS). During the insertion experiment three stages were observed, which can be related to three different phases, predominantly consisting of TCNQ, TCNQ and TCNQ 2−.

2018年2月14日 · The XPS pattern of the Cu (TCNQ) NA/CF reveals the presence of Cu and N elements. The strong peak of N1s at 398.3 eV appears as a single feature (figure 1 (e)) and proved that there is only one type TCNQ [20].

The substrate to TCNQ film electron transfer is accompanied by an XPS peak shift toward higher binding energies in both C1s and N1s spectra. This progressive XPS peak shift is indicative of a band bending in the TCNQ –film interface.
