Electrically tunable moiré magnetism in twisted double bilayers of chromium triiodide
Guanghui Cheng, Mohammad Mushfiqur Rahman, Andres Llacsahuanga Allcca +10
Moiré superlattices in van der Waals structures can be used to control the electronic properties of the material and lead to emergent correlated and topological phenomena. Its firs…
Emergence of electric-field-tunable interfacial ferromagnetism in 2D antiferromagnet heterostructures
Guanghui Cheng, Mohammad Mushfiqur Rahman, Zhiping He +12
Van der Waals (vdW) magnet heterostructures have emerged as new platforms to explore exotic magnetic orders and quantum phenomena. Here, we study heterostructures of layered antife…
Theoretical phase diagram for the room temperature Electron-Hole Liquid in photo-excited quasi-2D monolayer MoS
Avinash Rustagi, Alexander F. Kemper
Strong correlations between electrons and holes can drive the existence of an electron-hole liquid (EHL) state, typically at high carrier densities and low temperatures. The recent…
Sub-picosecond acoustic pulses at buried GaP/Si interfaces
Kunie Ishioka, Avinash Rustagi, Andreas Beyer +5
We report on the optical generation and detection of ultrashort acoustic pulses that propagate in three-dimensional semiconductor crystals. Photoexcitaiton of lattice-matched GaP l…
Intrinsic coherent acoustic phonons in indirect band gap semiconductors Si and GaP
Kunie Ishioka, Avinash Rustagi, Ulrich Hoefer +2
We report on the intrinsic optical generation and detection of coherent acoustic phonons at (001)-oriented bulk Si and GaP without metallic phonon transducer structures. Photoexcit…
