High chern number
WebThen, the two-dimensional subsystem is a quantum Hall insulator with unit Chern number. When the system is given a boundary at \(z = 0\), we expect a chiral edge state for this subsystem [see Fig. 6(b)]. Hence, this … WebRemarkably, a QAH phase of high Chern number C = 3 is found, and there are three corresponding gapless chiral edge states emerging inside the bulk gap. Different substrates are also chosen to study the possible experimental realization of the 1T-YN 2 monolayer, while retaining its nontrivial topological properties.
