Application of scanning probe microscopy

The aim of the research is capturing high-resolution atomic force microscopy images from nanostructures, from materials science samples or even from biological samples using a Bruker Dimension Icon set. The tool diameter is 210 mm and is equipped with a general purpose vacuum probe holder, ensuring the possibility of a large surface area measurements. Our research can be carried out in air and fluid medium. In addition to the topological imaging of materials, we also researching the nano-electrical and nano-mechanical properties of the material.

CVD: Chemical Vapour Deposition Technique for synthesis of diamond layers

In this lab our main research field is to study the synthesis of diamond phase thin layers deposited by MPECVD (Microwave Plasma Enhanced Chemical Vapour Deposition): investigation of the formation of micro-, nano- and ultrananocrystalline phase of diamond layers; MEMS-, sensor- and 3D coating applications of MPECVD diamond, SAD (Selective Area Deposition) of diamond, coating technology for passivation; investigation the formation, properties and applications of active color centers in diamond for quantum optics and photonic applications; In 2020 in co-operation with the Wigner Research Centre for Physics we installed a new, compact, modular built MPECVD platform in the Institute for Solid State Physics and Optics, Department of the Applied and Nonlinear Optics, and based on this agreement the operation of the equipment and the research activity will be proceeded in Wigner-RC in co-operation with the Department of Atomic Physics of FNS, BME.

LIBS: Laser Induced Breakdown Spectroscopy

The Laser Induced Breakdown Spectroscopy is a widely used method for materials characterization. Using a high energy laser pulse focused on the sample a small amount of the material will be vaporized transforming the components of the measured sample to plasma state. Analysing the spectra of this plasma the composition of the material can be determined. In the Department of the Atomic Physics the LIBS measurements are supported by an Andor Mechelle 5000 echelle spectrograph equipped with an Andor iStar 734 ICCD camera, a Quantel Brilliant and an EKSPLA NL300 Nd:YAG laser sources. In addition, for on-the spot measurements we have a portable instrument: Porta-LIBS 2000 by Stellarnet Inc.
