报告摘要：At low temperature and in magnetic field, high quality 2D electron system(2DES)shows rich phases demonstrating various behaviors.Among these phases,the Winger crystal(WC)is one of the earliest predicted many-body phases of an interacting electron system: it is expected to be a periodic array of electrons with long-range order, when the electron Coulomb repulsion energy dominates over the kinetic energy. In this report,I would like to introduce my works on exploring the properties of wC phase of 2DES in GaAs quantum well,including probing the lattice structure of WC with another many-body phase of 2DES, and a new method to precisely map out the WC phase diagram.
