Abstract
About 20 nm large LiNbO3 nanocrystals are produced by high-energy ball milling, and then suspended in water by surrounding them with amyl acetate ligands. The formed colloids are allowed to penetrate into etched swift heavy ion tracks in an oxide layer on silicon. After appropriate contacting, both a source-drain and a gate voltage are connected to the resulting electronic structure. Depending on the applied external voltages, the current-voltage characteristics shows peculiar properties, ranging from Ohmic-type via forward- or backward-rectifying types up to double-rectifying types, eventually with hysteresis showing up. These structures could become relevant to gas sensorics.

N1 - Funding Information: A part of this work (yet unpublished) was performed more than a decade ago at the former Hahn-Meitner-Institute (HMI) Berlin. We are specially obliged to Mrs. Bloeck and to Dr. Giersick, both from former HMI Berlin, for performing the TEM imaging. Also thanks to Dr. P. Apel from JINR Dubna for providing us with the nanoporous PET foils used here, and to the crew of the former swift heavy ion accelerator ISL at HMI Berlin, for enabling the irradiation of the Si/SiO 2 structures. Finally, we are obliged to Prof. L.T.Chadderton (formerly: ANU Canberra; now deceased) for leaving us the TEM micrograph for illustration of the technique of anisotropization of materials by energetic ion impact. D.F. thanks the Universidad Autónoma Metropolitana, Cuajimalpa, México City for his former invitation as guest researcher in the frame of the Cathedra “Alonso Fernandez", and J.V. the Grant Agency of the Czech Republic (No. 19-02804S ) regarding the possible application of these novel nanostructures as gas sensors. P. H. is grateful to the Deutsche Forschungsgemeinschaft (DFG) for financial support in the frame of the former SFB 173 with respect to high-energy ball milling. D. Fink Study at the Free University of Berlin (1974: PhD in Physics). Scientist at Hahn-Meitner-Institute Berlin (1974-2008). Since 2008: work at UAM Mexico as guest professor.
