SUMMARY:RTG Colloquium: Bruno Schuler
DESCRIPTION:Probing atomic defects in 2D semiconductors with light-coupled STM\n\n\n\nEmpa\, Switzerland \n\n\n\n \n\n\n\nTwo-dimensional (2D) semiconductors provide an exciting platform to engineer atomic quantum systems in a robust\, yet tunable solid-state system. This talk explores the intriguing physics of single point defects in transition metal dichalcogenide (TMD) monolayers\, investigated through atomically resolved scanning probe microscopy. \n\n\n\nWe demonstrate electrically induced exciton emission from both pristine MoS₂ and individual charged defects using scanning tunnelling microscope luminescence (STML) on ultrathin hBN decoupling layers [1]. Furthermore\, I will present our recent advances in time-resolved THz-STM using QEV maps to achieve state-selective ultrafast charge injection [2]. This approach enables the investigation of charge [3] and exciton dynamics [4] with atomic spatial\, millielectronvolt energy\, and picosecond temporal resolution. \n\n\n\nBy combining the structural and electronic properties accessible by conventional scanning probe microscopy with the optical fingerprint from STML and the excited-state dynamics revealed through pump-probe THz-STM\, we gain a comprehensive microscopic understanding of localized quantum states in low-dimensional materials. \n\n\n\n \n\n\n\n[1] L.

SUMMARY:Workshop: Drama and the Scientist
DESCRIPTION:One-day in person workshop with Julie Stearns (professional theater director & artistic director) for RTG 2905 students. \n\n\n\n\n\n\n\n\n\n\n\nTheater training for effective communication\n\n\n\nJulie Stearns\, impuls plus \n\n\n\n \n\n\n\n“Scientists often try to avoid dramatization – but on the stage\, the dramaturgy of a performance is the result of techniques that can be learned and applied. This workshop prepares participants for the challenges of interaction in academic and research settings\, especially when the goal is to engage and persuade an audience. Through exercises in physical presence and voice\, participants develop a new awareness of how to shape their own performance\, while also gaining confidence in improvisation.” [J. Stearns\, impuls plus] \n\n\n\n \n\n\n\nVenue: RUN Auditorium
