Topological Semimetal KAlGe with Novel Electronic Instability

Topological Semimetal KAlGe with Novel Electronic Instability

Compounds with an anti-PbFCl structure exhibit a variety of electronic instabilities and intriguing physical properties. NaAlSi and NaAlGe are similar topological nodal-line semimetals, but they have distinct properties. NaAlSi is a superconductor at 6.8 K, whereas NaAlGe is an insulator with a pseu...
