Electronic manipulation of polar order in electron crystal
Takashi Kikkawa, Ziyan Chen, Yuto Fujimoto +8
When interaction among atoms or ions is strong enough, they often arrange periodically, forming a crystal. The arrangement patterns of atoms or ions can encode information, a conce…
Negative longitudinal resistance of monolayer graphene in the quantum Hall regime
Alexey A. Kaverzin, Shunsuke Daimon, Takashi Kikkawa +2
In the quantum Hall regime the charge current is carried by ideal one-dimensional edge channels where the backscattering is prohibited by topology. This results in the constant pot…
