A stable superconducting state at 8 K and ambient pressure in $$\alpha _t - (BEDT - TTF^ \star )_2 I_3 ^1 $$

Resonant Raman scattering from superconducting single crystals of (BEDT-TTF)2I3

“…1. These spectra are similar to those reported by Swietlik et al [9,11]. However, the spectrum of a,-(BEDT-TTF)2 13 ( Fig.…”

Development of Conductive Organic Molecular Assemblies: Organic Metals, Superconductors, and Exotic Functional Materials

“…436,437 Scanning tunneling microscope (STM) measurements revealed that the surface structure of -(ET) 2 I 3 crystals contains many defects, voids, and reconstruction of donor packing ( The polymerized anion molecules in -(ET) 2 Cu(NCS) 2 form an anion layer having openings, as seen in Fig. 33.…”

“…827,828 This finding suggests the occurrence of superconductivity below 9 K, which substantially exceeds that of the previous work and is comparable to that of the single crystal. 449 Thin films of iodine-doped NiPc were also grown on a quartz glass substrate 829 in the same manner as TTF Á I 0:71 . Interestingly, it shows metallic behavior, although the RT value is as low as 0.1-1 S cm À1 .…”

“…449,450 Since the T c % 8 K phase thus obtained was stable and can be isolated at ambient pressure, it was designated as t -(ET) 2 I 3 . The AMRO was first observed on -(ET) 2 IBr 2 499 and -(ET) 2 I 3 , 500 and subsequently has been utilized to study the precise shape of the Fermi surface topologically.…”

Optical Absorption of Polymer Films Doped with BEDT-TTF Polyiodides

“…The attempt is to make use of the well known conversions of α-(BEDT-TTF)2I3 crystals into the superconducting phase αt-(BEDT-TTF)2I3 [5,6] or the transformations of the various BEDT-TTF polyiodides into the α-or,β*-phase of (BEDT-TTF) 2 I3 7]. Such superconducting polymer films are very interesting due to their potential applications.…”
