Capacitive Response of Wigner Crystals

ORAL

Abstract

Here, we report our capacitance measurement of Wigner crystal near $ u$ = 1/5. We observe an anomalously large capacitance when the crystal forms, which is likely caused by the polarization charge. Our thorough study reveals several interesting new features, and shine light on the study of the dynamic response of this electron solid phase.
