Defects in crystalline solids are ubiquitous. It is the second law of thermodynamics that gives rise to the appearance of a certain amount of disorder in materials at finite temperatures. Defects have a strong influence on the electronic, optical, thermal, and mechanical properties of the solids, normally deteriorating their characteristics, but they can also be useful, e.g., for doping of semiconductors or quantum computing. Defects are also present in two-dimensional (2D) materials, which have recently been on the forefront of research in materials science, physics and chemistry. The reduced dimensionality of 2D materials, strongly affects the behavior of native and irradiation-induced defects in these systems, so that many concepts of the physics of defects in bulk systems are not applicable for 2D materials or requirem substantial modifications. The goal of the Seminar is to bring together active researchers in the field to discuss "state of the art" in theory and experiment dealing with the physics of defects in 2D materials. The effects of various imperfections on the properties of 2D systems will be addressed. The attendees will learn about recent developments in the theorectical methods and characterization techniques used to study deffects in 2D materials. Particular attention will be paid to defects in technologically important graphene and transition metal dichalcogenides. The response of 2D materials to ion and electron irradiation will also be addressed. The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
