AbstractParticle-like topological structures such as polar skyrmions in ferroelectrics have the potential for application in high-density information storage. Since the polar topologies arise from a complicated competitive energy balance, such non-trivial topological states are difficult to manipulate by applying non-persistent external stimuli, such as bias or strain. Thus, a flexible strategy for manipulating topological polar states is needed to realize ultrahigh-density topological devices.

AbstractElectrochemical deposition has been widely used to prepare conformal coatings but has rarely been used to design well-defined micro/nanostructures. Here we report electrochemical synthesis of complex, hierarchical inorganic microarchitectures simply via programming the applied potential waveforms. We identify two distinct electrochemical growth modes—the stacking mode and the flattening mode—under different potential waveforms.
