英文摘要 | This paper reports that a charge-transfer salt dibutylammonium bis-7,7,8,8-tetracyanoquinodimethane [DBA (TCNQ)(2)] has been prepared. The temperature dependences of the DC electrical conductivity of the DBA (TCNQ)2 single crystal measured along the crystallographic a, b, and c axes are reported. The crystal shows semiconducting behaviour and the room-temperature conductivities are highly anisotropic (sigma(a) = 3.63 x 10(-4)S/CM, sigma(b) = 2.84 x 10(-6)S/cm, and (sigma(c) = 1.82x 10(-5)S/cm). Particularly, a sharp semiconductor to semiconductor transition has been observed around 270 K on the resistivity curves measured under cooling and heating. In addition, thermal hysteresis phenomena on conductivity and differential scanning calorimetry curves are also reported.; Physics, Multidisciplinary; SCI(E); EI; 中国科学引文数据库(CSCD); 4; 6; 2251-2256; 17 |
