Electron-Phonon Coupling Drives the Gapless Charge Density Wave in Few-Layer 1T-VSe 2
The driving mechanism of the charge density wave (CDW) remains debated, particularly between Fermi surface nesting (FSN) and electron-phonon coupling (EPC) scenarios. Here, gate-tunable electrical and thermoelectric transport measurements were used to probe the CDW-related electronic structure in few-layer 1T-VSe...
