Z. Baji et al: Atomic layer deposition and characterization of Zn-doped Ga2O3 films
The present work focuses on the atomic layer deposition (ALD), annealing, and Zn doping of gallium oxide (Ga2O3) films using a novel Ga precursor, hexakis-dimethylamino-digallium. As ALD deposited Ga2O3 films are always amorphous, the optimal annealing procedure had to be found to achieve crystalline beta -Ga2O3. The bandgaps and dielectric properties of the layers were measured and the effects of the deposition parameters and postdeposition annealing on the [...]

L. Pósa et al: Noise diagnostics of graphene interconnects for atomic-scale electronics
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.

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