Bati2sb2o
웹We report an optical spectroscopy study on single crystals of Na2Ti2As2O, a sister compound of the superconductor BaTi2Sb2O. The study unexpectedly reveals two density wave phase transitions. The first transition, at 320 K, results in the formation of a large energy gap and removes the majority of the Fermi surfaces. But the compound remains metallic with … 웹2024년 8월 19일 · Δ E is determined as double the energy of the lowest level. This demonstrates that the CBS energies are proportional to half-odd integers. The solid line is calculated using EL /Δ E = EL / ( Δ2 ...
