“…The proposed new mechanism can not only help deepen the understanding of the formation and evolution of the seedlayer, but also provide a new method for the controllable growth of nanomaterials. Continuing with the growth mechanism study, Huang et al [2] investigated the controlled synthesis and the growth mechanism of two-dimensional (2D) ZnO by surfactant-assisted ion-layer epitaxy (SA-ILE), by controlling the growth parameters, such as the amounts of surfactant, temperature, precursor concentration, and growth time. Their work might guide the development of SA-ILE and pave the way for practical applications of 2D ZnO on photodetectors, sensors, and resistive switching devices.…”
