Emergent Trion Resonance Driven by Lattice Reconstruction in a Moiré Superlattice
Zhida Liu, Haonan Wang, Xiaohui Liu +20
We investigate how many-electron excited states emerge in twisted MoSe2 homobilayers when the lattice reconstructions evolve. Notably, we identify a new trion resonance that arises…
Electrostatic moiré potential from twisted-hBN layers
Dong Seob Kim, Roy C. Dominguez, Rigo Mayorga-Luna +17
Moiré superlattices formed by vertically stacking van der Waals layers host a rich variety of correlated electronic phases and function as novel photonic materials. The moiré poten…
Implementing Microwave Impedance Microscopy in a Dilution Refrigerator
Zhanzhi Jiang, Su Kong Chong, Peng Zhang +5
We report the implementation of a dilution-refrigerator-based scanning microwave impedance microscope (MIM) with a base temperature of ~ 100 mK. The vibration noise of our apparatu…
Nanoscale Imaging of Super-High-Frequency Microelectromechanical Resonators with Femtometer Sensitivity
Daehun Lee, Shahin Jahanbani, Jack Kramer +2
Implementing microelectromechanical system (MEMS) resonators calls for detailed microscopic understanding of the devices, such as energy dissipation channels, spurious modes, and i…
Observation of Gigahertz Topological Valley Hall Effect in Nanoelectromechanical Phononic Crystals
Qicheng Zhang, Daehun Lee, Lu Zheng +8
Topological phononics offers numerous opportunities in manipulating elastic waves that can propagate in solids without being backscattered. Due to the lack of nanoscale imaging too…
Nonvolatile Electric-Field Control of Inversion Symmetry
Lucas Caretta, Yu-Tsun Shao, Jia Yu +20
In condensed-matter systems, competition between ground states at phase boundaries can lead to significant changes in material properties under external stimuli, particularly when…
