We explain how to understand the relationship between the structural modes of 2D halides and their orbital order, why they're all insulating; e.g. RuCl3 can never have 3 degenerate t2g states. This applies to other materials with edge-connected octahedra. journals.aps.org/prb/abstrac…

Trigonal symmetry breaking and its electronic effects in the two-dimensional dihalides $M{X}_{2}$...

We study the consequences of the approximately trigonal (${D}_{3d}$) point symmetry of the transition metal ($M$) site in two-dimensional van der Waals ${MX}_{2}$ dihalides and ${MX}_{3}$ trihalides....

Congrats to Nathan and Lauren on the design of an oxynitride compound exhibiting a metal-insulator transition; work supported by @NSF_MPS and @NUMRSEC. journals.aps.org/prl/abstrac…

Design of Heteroanionic MoON Exhibiting a Peierls Metal-Insulator Transition

Using a first-principles approach, we design the heteroanionic oxynitride MoON to exhibit a first-order isosymmetric thermally activated Peierls-type metal-insulator transition (MIT). We identify a...

Tunable inversion symmetry to control indirect-to-direct band gaps transitions

Electric-field tunable indirect-to-direct band gap transitions occur in thin-film silicon and transition metal dichalcogenides; however, they remain challenging to access in three-dimensional...
