In this study, we demonstrate the effects of surfactants on morphology Nb2C MXene-derived ferroelectric KNbO3 crystals. We synthesized plate-like crystals using MXene and KOH as niobium potassium sources, respectively, sodium dodecyl sulfate surfactant. addition, conducted same hydrothermal process for benzyltriethylammonium chloride a surfactant; found that final product exhibits bulk morpholo...
