| Abstract Scope |
Piezoelectric and semiconducting materials have drawn intense interest for their excellent potential to advance the field of wearable electronics and piezotronic devices. Moreover, two-dimensional (2D) nanomaterials, valued for their enhanced mechanical, electronic, and structural properties, have moved to the forefront of compliant electronic devices. Therefore, a thorough understanding of the size effects in piezoelectric semiconductors such as zinc-oxide (ZnO), is required at the nanoscale. We present a thickness-dependent study of the piezoelectric response of nanometer-thick 2D ZnO nanosheets (NS) grown via Ionic Layer Epitaxy (ILE) with unit cell precision. The size dependence of the piezoelectric effect within ZnO-NSs, is monitored in situ via piezo force microscopy (PFM). Using PFM, we illustrate the size effects of piezoelectric nanomaterials and its role in the polarization charge distribution across the surface of the 2D ZnO-NS for future piezotronic applications. |
