Correlated Charge Density Wave Insulators in Chirally Twisted Triple Bilayer Graphene Open
Electrons residing in flat-band system can play a vital role in triggering spectacular phenomenology due to relatively large interactions and spontaneous breaking of different degeneracies. In this work we demonstrate chirally twisted trip…

Metastable Charge Distribution Between Degenerate Landau Levels Open
We study two dimensional electron systems confined in wide quantum wells whose subband separation is comparable with the Zeeman energy. Two N = 0 Landau levels from different subbands and with opposite spins are pinned in energy when they …

Dynamic Response of Wigner Crystals Open
The Wigner crystal, an ordered array of electrons, is one of the very first proposed many-body phases stabilized by the electron-electron interaction. This electron solid phase has been reported in ultra-clean two-dimensional electron syst…

High Precision, Low Excitation Capactiance Measurement Methods from 10 mK- to Room-Temperature Open
Capacitance measurement is a useful technique in studying quantum devices, as it directly probes the local particle charging properties, i.e. the system compressibility. Here we report one approach which can measure capacitance from mK to …

Capacitive Response of Wigner Crystals at the Quantum Hall Plateau Open
In this report, we study ultra-high-mobility two-dimensional (2D) electron/hole systems with high precision capacitance measurement. We find that the capacitance charge appears only at the fringe of the gate at high magnetic field when the…

Contactless transport method of two-dimensional electron system studies Open
We introduce two contactless measurement methods at extremely low temperature: capacitances and surface acoustic waves. Both methods can be used to study the physical properties of the quantum system through the interaction between electro…
