The present work demonstrates that the three Raman modes observed above 220cm1 (high frequency region) at room temperature exhibit remarkable frequency changes toward low wavenumbers in the vicinity of 200K, where 1T-TaS2 undergoes a first-order transition of the charge density wave (CDW) from ...
Although we analyze the full RPES range, we restrict the quantitative Raman fraction and charge transfer time analysis to the 227.5–228.5 eV photon energy range, just above the Fermi level. Here, the l- and d-channels are ideally separable and address the physically relevant density of ...

With this method we are able to image metastable states occurring in the transition between the nearly commensurate and commensurate charge density wave state in bulk 1T-TaS2 and compare the results to Raman spectroscopy. 展开 关键词: A. Transition metal dichalcogenides D. Phase transitions E. ...
随着电场的增加,不同CDW状态的停留时间也发生了变化。在较低温度下,由于中间相之间的较高能量势垒和较低温度下较低的热激发能量,多态振荡消失。相关成果以“Raman Spectroscopic and Dynamic Electrical Investigation of Multi-State Charge-Wave-Density Phase Transitions in 1T-TaS2”为题发表在Nano Letter上。
The multiple-excitation results show a selective coupling of each Raman-active phonon with specific electronic transitions hidden in the optical spectra of 1T-TaS2, suggesting that selectivity in the electron–phonon coupling must also play a role in the CDW order of 1T-TaS2....
