WebAug 11, 2024 · Charge density wave (CDW) is a periodic modulation of electron density in real space below the critical temperature (T CDW), which opens a gap at the zone boundary of the new unit cell [].This charge density modulation changes the potential in the lattice so that the ions move to new equilibrium positions, resulting in a periodic lattice distortion. WebUnlike the robust transition in η -Mo 4 O 11, the CDW modulation in γ -Mo 4 O 11 is rather broad and flexible, which results in negligible anomaly in specific heat. (2) γ -Mo 4 O 11 shows a clear nonlinear current-voltage relation below T CDW due to a sliding motion of the CDW electrons. recording king rphWebJul 11, 2024 · Moiré Modulation of Charge Density Waves.
