Atomic engineering of interfacial polarization switching in van der Waals multilayers
Madeline Van Winkle, Nikita Dowlatshahi, Nikta Khaloo +6
In conventional ferroelectric materials, polarization is an intrinsic property limited by bulk crystallographic structure and symmetry. Recently, it has been demonstrated that pola…
Molecular beam epitaxy growth of cadmium telluride structures on hexagonal boron nitride
Adam Krzysztof Szczerba, Julia Kucharek, Jan Pawłowski +3
We investigate the feasibility of epitaxial growth of a three-dimensional semiconductor on a two-dimensional substrate. In particular, we report for the first time on molecular bea…
Quantum Octets in Air Stable High Mobility Two-Dimensional PdSe2
Yuxin Zhang, Haidong Tian, Huaixuan Li +10
Two-dimensional (2D) materials have drawn immense interest in scientific and technological communities, owing to their extraordinary properties that are profoundly altered from the…
Exciton-exciton Interaction in Monolayer MoSe from Mutual Screening of Coulomb Binding
Ke Xiao, Tengfei Yan, Chengxin Xiao +7
The potential for low-threshold optical nonlinearity has received significant attention in the fields of photonics and conceptual optical neuron networks. Excitons in two-dimension…
Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride
Håkon I. Røst, Simon P. Cooil, Anna Cecilie Åsland +9
Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body e…
Berry Curvature Signatures in Chiroptical Excitonic Transitions
Samuel Beaulieu, Shuo Dong, Viktor Christiansson +10
The topology of the electronic band structure of solids can be described by its Berry curvature distribution across the Brillouin zone. We theoretically introduce and experimentall…
