Electrically and optically active charge carrier traps in silicon-doped few-layer GaSe
M. Bissolo, R. Li, M. Ogura +9
Understanding defects in atomically thin van der Waals (vdW) semiconductors is essential for advancing their use in next-generation optoelectronic and photovoltaic devices. Here, w…
Van der Waals CrSBr alloys with tunable magnetic and optical properties
Shalini Badola, Amit Pawbake, Bing Wu +4
Van der Waals magnets are attracting a lot of attention for their potential integration in spintronic and magnonic technologies. CrSBr is an A-type antiferromagnet that shows a cou…
Wafer-Scale Films of Two-Dimensional Materials via Roll-to-Roll Mechanical Exfoliation
Yigit Sozen, Thomas Pucher, Bhagyanath Paliyottil Kesavan +6
In this study, we demonstrate an improved version of the roll-to-roll mechanical exfoliation method, incorporating a controlled sliding motion into the exfoliation process to achie…
Magnetic phases and zone-folded phonons in a frustrated van der Waals magnet
A. Pawbake, F. Petot, F. Le Mardelé +14
2D magnetic materials have attracted extensive research interest due to their potential application in nanospintronics, optospintronics, and in magnonics. Ferromagnetic as well as…
Electric-field switchable chirality in rhombohedral graphene Chern insulators stabilized by tungsten diselenide
Jing Ding, Hanxiao Xiang, Jiannan Hua +10
Chern insulators host topologically protected chiral edge currents with quantized conductance characterized by their Chern number. Switching the chirality of a Chern insulator, nam…
