High chern number
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. http://isynonym.com/en/high-number
