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…
