Giant nonlinear conduction in the charge ordered organic conductor theta-(BEDT-TTF)(2)MM'(SCN)(4) (M = Cs Rb M' = Co Zn) is analyzed in relation to the current-induced suppression of the charge ordered state characterized by a wave vector of q(2) = (0k 1/2) On the basis of a theory of the nonequilibrium Peierls transition the energy gap is calculated as a function of current density J(ext) which is found to depend weakly on temperature in an intermediate temperature range This justifies the evaluation of the found to be consistent with the calculation We compare the present results with nonequilibrium and Ail i IS charge-order energy gap Delta from the nonlinear resistivity rho assuming rho proportional to exp[Delta(J(ext))/k(B)T] and Delta(J(ext)) superconducting states induced by excess quasiparticles and discuss a mechanism of current-Induced suppression of the charge ordering in the title compound (C) 2009 Elsevier B V All rights reserved
