The pure (x = 0) single crystals show only one TSDC peak at 183 K with the maximum current of 5.5 nA, which is attributed to 'detrapping of charge carriers'. But three peaks were observed in impurity doped (x =1 and 2 mole %) Cu(HCOO)2 single crystals. The maximum current in these crystals was in the order of few microamps. The two new peaks have been assigned to ‘Trap-limited band transport model’ and ‘Maxwell-Wagner effect’. Relaxation parameters and activation energies of these crystals have been calculated.</span
