Metal-chalcogen bond-length induced electronic phase transition from semiconductor to topological semimetal in ZrX${}_2$ (X = Se and Te)

I. Kar, Joydeep Chatterjee, Luminita Harnagea +6

Using angle resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations we studied the low-energy electronic structure of bulk ZrTe${}_2$. ARPES stud…
