SPECIFIC-HEAT OF THE ORGANIC METAL BIS(TETRATHIOTETRACENE) TRI-IODIDE FROM 20-K TO 100-K, THE VICINITY OF THE METAL-NONMETAL PHASE-TRANSITION Academic Article uri icon

abstract

  • Specific-heat measurements on pressed pellet samples of highly disordered bis(tetrathiotetracene) tri-iodide (TTT2I3) have been made from 20 to 100 K using thermal relaxation methods. An anomaly at 50 K in the form of a broad bump is reported which is coincident with magnetic susceptibility structure and occurs approximately 25 K above anomalies in electrical and optical behavior. The specific-heat discontinuity is consistent with a mean-field model for a Peierls phase transition with correction for fluctuations. 1981 The American Physical Society.
