We have demonstrated that the advanced analysis of low-frequency noise measurements supplies a rich source of information on the controlled electrobreakdown process of graphene nanojunctions. Following the evolution of the relative noise amplitudes we were able to optimize the electrical breakdown protocol and to identify distinct regimes of the nanogap formation process.

…published in MDPI Nanomaterials (link) by the Nanosensors Group in cooperation with other MFA teams Here, we propose and optimize a simple fabrication method for VO2 rich layers by the oxidation of metallic vanadium in atmospheric air. It was shown that a sufficiently broad annealing time window of 3.0–3.5 h can be obtained at an optimal oxidation temperature of 400 °C.

We have shown by Piezoresponse Force Microscopy (PFM) that the quality of the deposited AlN layer depends strongly on the negative substrate bias, i.e., the energy transferred via the bombardment of the accelerated positive ions on the sample.
