Ambipolar to unipolar irreversible switching in nanosheet transistors: the role of ferrocene in fullerene/ferrocene nanosheets

Abstract

Recently, cocrystals containing organic donors and acceptors have been explored as active elements in organic field-effect transistors (FETs). Herein, we report the ambipolar charge transport properties of C60/ferrocene (C60/Fc) single...

Fullerene C70/porphyrin hybrid nanoarchitectures: single-cocrystal nanoribbons with ambipolar charge transport properties

“…[27][28][29] Recently, we succeeded in evaluating the electronic structure of C 60 /Fc nanosheets with high sensitivities using PYSA. 30 The ionization energy (I s ) of the C 70 /3,5-TPP nanoribbons was determined to be 5.71 eV, which is 0.51 eV smaller than that of the C 70 powder, similar to that of 3,5-TPP. Fig.…”

Ambipolar Charge Transfer of Larger Fullerenes Enabled by the Modulated Surface Potential of H-Bn/Rh(111)

“…Previous research has shown promising results in overcoming the challenges to achieve ambipolar charge transport in fullerenes by designing fullerene derivatives [12,13], synthesizing metallofullerene peapods to reduce the HOMO-LUMO gap [14], or introducing co-crystals that contain organic donors and acceptors [15]. However, these approaches significantly increase the complexity of the devices.…”

Ambipolar to Unipolar Conversion in C70/Ferrocene Nanosheet Field-Effect Transistors

“…Hence, fabricating organic cocrystals provides a feasible means of obtaining ambipolar materials; nevertheless, the preparation of these semiconductors remains a challenge owing to complex organic syntheses. However, using a simple and efficient liquid-liquid interfacial precipitation method for the synthesis of low-dimensional nanomaterials based on fullerenes [33][34][35][36][37], our group has successfully synthesized cocrystals of fullerenes with ambipolar transport characteristics [1,38,39]. Recently, we successfully demonstrated the capability to irreversibly switch the electrical properties of C 60 /Fc nanosheets from ambipolar to unipolar by thermal stimulation [39].…”

Recently, we successfully demonstrated the capability to irreversibly switch the electrical properties of C 60 /Fc nanosheets from ambipolar to unipolar by thermal stimulation [39]. However, the C 60 /Fc nanosheet devices were thermally unstable-more than half of the C 60 /Fc nanosheet devices lost their ambipolar properties below 80 • C [39].…”
