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.
