Lanthanide complexes as molecular dopants for realizing air-stable n-type graphene logic inverters with symmetric transconductance

Abstract

In this communication we have unveiled the importance of lanthanide dopant, to realize n-doping of GFETs with an exceptional ambient stability and enhanced mobility. An unconventional mechanism proposed for such phenomenon is well supported by various analytical methods and rationalized by computational calculations.

“…The detailed synthetic procedure and crystal structure of 1 were reported by us elsewhere, which is the first air-stable inorganic dopant that stabilizes the N-doping of graphene field-effect transistors with exceptional ambient stability of the device. 30 In the crystal lattice of 1, there are no solvate molecules and the complex is stable up to 350 °C as revealed by thermogravimetric analysis (TGA) reported elsewhere (called the data again in Fig. S1 of the ESI †).…”

“…Beyond this, domain 2 (blue, Figure b) is marked by the saturation of the signal response and extends up to pH 2 S of 330 ppb. The observed saturation in the signal from the cCNT corresponds to the saturation of its surface with H 2 S. The Stone–Wales defect centers on the cCNT act as pinning points for the π-electron charge density and hence form the preferred reactive sites.…”
