General description

Bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) is an organic superconducting polymer that is used as an electron donor with a superconducting transition temperature (Tc) of 10K.

Application

BEDT-TTF may be used as a counter-anion with tetrathiocyanatocuprate which can be prepared by the galvanostatic electrocrystallization process. It may also be used in the preparation of novel paramagnetic conductors by synthesizing multifunctional molecular materials with manganese containing complexes. BEDT-TTF based doping may be used in the fabrication of a hybrid organic change generation layer which can potentially be used in the development of tandem organic light emitting diodes (OLEDs).
Used as a component for organic superconductors.

A Mott insulator sometimes induces unconventional superconductivity in its neighbors when doped and/or pressurized. Because the phase diagram should be strongly related to the microscopic mechanism of the superconductivity, it is important to obtain the global phase diagram surrounding the

The exotic properties of quantum spin liquids (QSLs) have continually been of interest since Anderson's 1973 ground-breaking idea. Geometrical frustration, quantum fluctuations, and low dimensionality are the most often evoked material's characteristics that favor the long-range fluctuating spin state without
