Description
ZrSiS is a layered Dirac semimetal known for its well-defined Fermi pockets and quantum transport features. It supports Weyl fermions under magnetic fields and is predicted to transition into a topological insulator under external stimuli. Crystals are typically 2–3 mm in size and are suitable for STM, ARPES, and electronic transport studies.
