摘要：

Electron band structure calculations reveal that ZrSe3 is a semiconductor with Eg approximately 1.5 eV whereas NbSe3 and TaSe3 are both highly anisotropic metals. The Peierls transition in NbSe3 is related to the presence of four quasi-one-dimensional free-electron-like bands crossing the Fermi energy. This feature does not exist in TaSe3, and the differences in properties are related to structural differences.
