W dniu 22.03.2019 Rada Wydziału Inżynierii Materiałowej i Ceramiki Akademii Górniczo-Hutniczej w Krakowie podjęła uchwałę o nadaniu dr Igorowi Iatsunskiemu stopnia doktora habilitowanego w dziedzinie nauk technicznych, w dyscyplinie inżynieria materiałowa.
The performance gain-oriented nanostructurization has opened a new pathway for tuning mechanical features of solid matter vital for application and maintained performance. Simultaneously, the mechanical evaluation has been pushed down to dimensions way below 1 μm. To date, the most standard technique to study the mechanical properties of suspended 2D materials is based on nanoindentation experiments. In this work, by means of micro-Brillouin light scattering we determine the mechanical properties, that is, Young modulus and residual stress, of polycrystalline few nanometers thick MoS2 membranes in a simple, contact-less, nondestructive manner. The results show huge elastic softening compared to bulk MoS2, which is correlated with the sample morphology and the residual stress.
The Organizing Committee of the NanoTech Poland 2019, 5th-8th June 2019 held in Poznań, has a great pleasure to invite you to attend this scientific event and to enjoy the community of professionals in the field of nanoscience and nanotechnology.
