(TaSe4)2I是一个非常有意思的材料。早在1982年就被合成出来，后续作为准一维的CDW材料已经被研究了很...
The vacuum ultraviolet photoemission spectra of quasi-one-dimensional charge density wave ( CDW ) system, (TaSe4)2I, were measured for photon energies between 32 and 100 eV at room temperature ( in the normal phase ) and at about 100 K ( in the CDW phase ). The spectrum of Ta 4f ...

We have measured the electric field dependence of the resonant period in linear chain conductor (TaSe)I using a vibrating reed technique. Transient behavior was observed in very low electric field, which seems to depend on the thermally and electrically deformed charge-density wave (CDW) states. ...

Hall effectcarrier densityWe present Hall effect measurements on the charge density wave (CDW) system ( TaSe 4) 2 I. The room temperature carrier density is found to be (1.7 卤 4). 10 21 cm 3. In the semi-conducting Peierls state the Hall voltage ( V H) is measured both below and...
Our theory qualitatively applies to the quasi-one dimensional CDW material (TaSe4)2I. This material exhibits peculiar properties: above the CDW transition temperature Tc, thermal fluctuations were found to die out rapidly, but robust pseudogap behavior is still detected. Namely, the experimental ...

We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe4)2I following ultrafast infrared photoexcitation. From the time-dependent diffraction signal at the CDW sidebands we identify a 0.11THz amplitude mode derived primarily from a transverse ...
