Abstract
The thermodynamic and transport properties of a long granular array with strongly connected grains (intergrain conductance g≫1) were studied. It was found that the system's conductance and differential capacitance exhibits activated behavior ∼ exp{-T*/T}. The gap T *represents the energy needed to create a long single-electron charge soliton propagating through the array. It was shown that the inelastic tunneling and weak charge quantization lead to the insulating behavior at the temperature below T*∼Ece-g/4.
