Flat Band and Many-body Gap in Chirally Twisted Triple Bilayer Graphene
Wenlu Lin, Wenxuan Wang, Shimin Cao +8
We experimentally investigate the band structures of chirally twisted triple bilayer graphene. The new kind of moiré structure, formed by three pieces of helically stacked Bernal…
Metastable Charge Distribution Between Degenerate Landau Levels
Wenlu Lin, Xing Fan, Lili Zhao +6
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 subba…
Correlated Charge Density Wave Insulators in Chirally Twisted Triple Bilayer Graphene
Wenxuan Wang, Gengdong Zhou, Wenlu Lin +16
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 dege…
Dynamic Response of Wigner Crystals
Lili Zhao, Wenlu Lin, Yoon Jang Chung +4
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…
High Precision, Low Excitation Capactiance Measurement Methods from 10 mK- to Room-Temperature
Lili Zhao, Wenlu Lin, Xing Fan +3
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 re…
Capacitive Response of Wigner Crystals at the Quantum Hall Plateau
Lili Zhao, Wenlu Lin, Y. J. Chung +3
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 onl…
