摘要：

Recently, we have shown that unconventional charge density wave (UCDW) is the most likely candidate for the unidentified low-temperature phase (LTP) in alpha-(ET), salts. In particular, UCDW describes reasonably well the temperature dependence of the threshold electric field of LTP in alpha-(ET)(2)KHg(SCN)(4). Here, we shall show that the imperfect nesting in UCDW is crucial to further improve the theoretical description of the threshold electric field. (C) 2002 Elsevier Science B.V. All rights reserved.
