Ultrathin Al-Driven Polarity Engineering in Polycrystalline ZnO Thin Films on Flexible Glass for Sign-Reversible Piezoresistive and Photoconductive Responses

Flexible transparent devices require materials whose mechanical and optoelectronic responses can be tuned in a coordinated manner through interface design. This study shows that an ultrathin Al underlayer enables crystallographic polarity switching in c-axis-oriented polycrystall...
