L. Pósa et al: A Rational Fabrication Method for Low Switching-Temperature VO2

January 15th, 2021|

…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. [...]

N. Q. Khánh et al: The effect of substrate bias on the piezoelectric properties of pulse DC magnetron sputtered AlN thin films

November 13th, 2020|

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. November 13 2020: N. Q. Khánh et al: The effect of substrate bias on the piezoelectric properties of pulse DC magnetron sputtered AlN thin films published in Journal of Materials [...]

Binderiya Oyunbolor (supervisor: Nguyen Quoc Khánh), Reactive magnetron sputtering of AlN and ScAlN thin films for piezoelectric applications Zsolt Filep (supervisor: István Endre Lukács), Two-dimensional electron gas based electromechanical microsensors A well-deserved congratulation to all of them!

Dose rate mapping measurement at the KFKI Campus using the DoziMobile unit

October 2nd, 2020|

In the frame of the DoziNet project it was demonstrated that the radiation detector system developed by the Space Research Laboratory for sounding rocket experiments could be combined with the communication units and protocol used and developed by the Nanosensors Department for self-organizing scalable networks and that the combined system could be integrated into the network of Geiger–Müller (GM) probes installed and operated by the Environmental Protection Service [...]
