Electronic Structure of Phase Separated Material Revealed by Nanospot Angle-Resolved Photoemission Spectroscopy

Phase separation frequently occurs in strong correlated materials. The electronic structures of different phases are very important but difficult to access due to very small grain size. As an electronic structure microscopy, nanospot angle-resolved photoemission spectroscopy (NanoARPES) can measure the electronic structure both in real and momentum spaces and provides the unique ability to measure the electronic structures of different phases in phase separated materials. Here I will present our recent experimental results on the electronic structure of phase separated material by using NanoARPES.
