The electric-field controlling of skyrmions in such devices is essential but remains technologically challenging. Here, using the first-principles calculation and the Ginzburg-Landau theory, we propose a reliable process for writing and deleting skyrmions by electric fields, on the platform of a multiferroic heterostructure, particularly the $\\text{Cr}_{2}\\text{Ge}_{2}\\text{Te}_{6} $/$ \\text{In}_{2}\\text{Se}_{3} $ heterostructure.
