6th Nanomaterials Webinar

Strain Engineering of 2D Materials

One of the most intriguing properties of two-dimensional (2D) materials is their high stretchability. In fact, these materials can sustain very large mechanical deformations without breaking. This remarkable mechanical resilience opens up the possibility to use external strain to manipulate, in a controlled manner, their optical and electronic properties. Therefore, strain engineering, the field of research that study how the physical properties of materials can be tuned by controlling the elastic strain fields applied to it, has found a perfect platform for its implementation in 2D materials. In this webinar we will count with leading experts that will review their contributions to this timely topic.

Spanish National Research Council (CSIC), Spain

Dr. Andres Castellanos-Gomez is a Tenured Scientist in the Spanish National Research Council (Consejo Superior de Investigaciones Científicas, CSIC). He explores novel 2D materials and studies their mechanical, electrical and optical properties with special interest on the application of these materials in nanomechanical and optoelectronic devices. He is author of ~150 articles in international peer review journals and 6 book chapters. He is the principal investigator of a prestigious ERC Starting Grant. Among other recognitions has been appointed Fellow of the International Association of Advanced Materials (IAAM) in 2020, has been included in the Highly Cited Researchers 2018, 2019 and 2020 lists of Clarivate/WOS and has been also recognized with the Young Researcher Award (experimental physics) of the Royal Physical Society of Spain (2016).

Invited Speakers

Sapienza Università di Roma, Italy

Prof. Antonio Polimeni coordinates the group of “Optical Spectroscopy of Nanostructured Materials” at the Physics Department, Sapienza Università di Roma ( During the PhD in Rome, his activity concerned the effects of disorder on the optical properties of semiconductor quantum wells. In the group of “Quantum Transport and Spectroscopy of Semiconductors” at the University of Nottingham, he investigated the transport, structural, and magneto-optical properties of quantum dots and their application as active medium in lasers. In particular, he engineered and characterized lasers based on InGaAs self-assembled quantum dots with top-notch performances. Back in Rome, he studied the electronic and optical properties of different semiconductor material systems also under high magnetic fields and hydrostatic pressure. Antonio Polimeni discovered the hydrogen-induced passivation of nitrogen atoms in dilute nitrides. This enabled the fabrication of novel nanostructures with planar architecture leading to the recent realization of site-controlled single photon sources embedded in photonic structures. He investigated also the structural, optical and magneto-optical properties of nanowires. He worked in several laboratories abroad: Philipps-University of Marburg, High Field Magnet Laboratory in Nijmegen (The Netherlands) and Grenoble, Synchrotron SOLEIL Paris, European Synchrotron Radiation Facility Grenoble. Recently, he pioneered a novel method for creating strain-engineered nanostructures via the formation of hydrogen bubbles in two-dimensional materials by hydrogen irradiation. He is author of 233 peer-reviewed papers, 5 contributed book chapters and 5 invited articles.

Free University of Berlin, Germany

Prof. Dr. Kirill Bolotin is an expert in the field of electron transport and optoelectronics of two-dimensional materials. He holds the chair of electrical transport in 2D materials. His main results include the discovery of the fractional quantum effect in graphene, the demonstration of strain-engineering of 2D MoS2, first measurements of the exciton binding energy in 2D MoS2, and the discovery of the renormalization of the elastic constants of the 2D materials. He was awarded the US NSF Career award (2010), the Sloan foundation award (2011), and the ERC starting grant (2016).

University of Münster, Germany

Dr. Steffen Michaelis de Vasconcellos received his PhD from the University of Paderborn. After his postdoc stay at the Laboratoire de Photonique et de Nanostructure (CNRS), Marcoussis, France, he moved to Chemnitz University of Technology. Currently, he is a senior scientist at the University of Münster. His research area is the experimental study of the light-matter interaction in low-dimensional semiconductor nanostructures. In the focus of his work are the ultrafast exciton dynamics in 2D materials, the coherent control of localized quantum systems and single-photon emitters.

Vienna University of Technology, Austria

Dr. Thomas Mueller received his M.S. and Ph.D. degrees in Electrical Engineering from TU Vienna in 2001 and 2004, respectively. In 2007 he joined the IBM Watson Research Center, USA, as a Postdoc, working on carbon-based optoelectronics. At the end of 2009 he returned to TU Vienna, where he currently holds an Associate Professor position. His research focuses on electronic and photonic devices based on two-dimensional materials. He (co-)authored more than 100 peer-reviewed publications in leading scientific journals. Selected awards include the START-Prize, the Fritz Kohlrausch-Prize, and the ASciNA Award.
