Anomalous CDW ground state in Cu2Se: A wave-like fluctuation of the dc I-V curve near 50 K

Anomalous CDW ground state in Cu2Se: A wave-like fluctuation of the dc I-V curve near 50 K

A charge density wave (CDW) ground state is observed in polycrystalline Cu2Se below 125 K, which corresponds to an energy gap of 40.9 meV and an electron-phonon coupling constant of 0.6. Due to the polycrystalline structure, the Peierls transition process has been expanded to a wide temperature rang...
