This investigation shows enhanced mobility and low resistivity in flexible ITO thin films, indicating low-temperature processing benefits.

Excellent performance was achieved with an Indium Tin Oxide resistivity of 203 μΩ·cm and 89.2% visible light transmittance.
Surface roughness was measured at 0.76 nm, and samples sustained 100,000 bending cycles with minimal resistance change.
Microstructural analyses were conducted to assess low-temperature deposition and subsequent atmospheric annealing effects.
These findings highlight the potential for flexible electronics and transparent electrodes utilizing low-temperature fabrication methods.

Zhang et al. (2025) studied this question.
