## Description

- description: Emergent functionalities created by applying mechanical stress to flexible
    devices using SnO2 microrods and Ga2O3/SnO2-core/shell microribbons are reviewed.
    Dynamic lattice defect engineering through application of mechanical stress and
    a voltage to the SnO2 microrod device leads to a reversible semiconductor-insulator
    transition through lattice defect creation and healing, providing an effective
    and simple solution to the persistent photoconductivity (PPC) problem that has
    long plagued UV semiconductor photosensors. Here, lattice defects are created
    near slip planes in a rutile-structured microrod by applying mechanical stress
    and are healed by Joule heating by applying a voltage to the microrod. Nanoscale
    amorphous structuring makes the Ga2O3/SnO2-core/shell microribbon with a large
    SnO2 surface area more sensitive to changes in temperature, while mechanical bending
    of the wet device improves its sensitivity to adsorbed water molecules. These
    results illustrate the potential for developing flexible devices with new functionalities
    by enhancing the intrinsic properties of materials through miniaturization, mechanical
    stress, and hybridization.
