Shift current in 2D Janus Transition-Metal Dichalcogenides: the role of excitons
Yuncheng Mao, Ju Zhou, Myrta Grüning +1
We investigate the shift current in two-dimensional (2D) Janus transition-metal dichalcogenides (TMDs). The shift current is evaluated using a real-time approach, where the couplin…

A real-time approach to frequency-mixing spectroscopies: application to sum and difference frequency generation in two-dimensional crystals
Mike N. Pionteck, Myrta Grüning, Simone Sanna +1
We propose a computational framework to extract non-linear response functions from real-time simulations in the presence of more than one external field. We apply this approach to…

Strain-Induced Decoupling Drives Gold-Assisted Exfoliation of Large-Area Monolayer 2D Crystals
Jakob Ziewer, Abyay Ghosh, Michaela Hanušová +5
Gold assisted exfoliation (GAE) is a groundbreaking mechanical exfoliation technique, producing centimeter scale single crystal monolayers of 2D materials. Such large, high quality…
