## Abstract We report here a curious effect of spontaneous fracturing of the silicon layers formed in galvanostatic conditions at medium and high current densities. Instead of formation of homogeneous pโSi layer as at low currents, a stack of thin layers is formed. Each layer is nearly separated fr
