Lars Breuer

Lars Breuer is a Principal Investigator at the Collaborative Research Centre 1242 (CRC 1242) at the University of Duisburg-Essen, focusing on particle-induced excitations in the time domain. His work centers on interactions between highly charged ions and low-dimensional materials, particularly graphene, MoS2, and black phosphorus systems.

• Key Research Areas: Ion irradiation effects, ultrafast electronic response of 2D materials, charge exchange dynamics, and surface modification at atomic scales
• Techniques: Time-resolved spectroscopy, supersonic gas beam ion sources, sputtering analysis, and pump-probe experiments

Recent publications highlight collaborations with Marika Schleberger's team and advancements in understanding nonequilibrium electron dynamics (2024) and ion-induced memory effects in 2D transistors (2023). His work bridges fundamental physics and applied material engineering through precise ion-beam manipulation.

Notable contributions include:

• Developing ultrashort ion pulse generation for time-domain studies
• Characterizing defect-induced properties in Janus MoSSe structures
• Investigating metal-2D material interfaces for optoelectronic applications
