Overview

Observational analysis shows improved hydrogen sensing performance in WO3 films, suggesting interfacial stress influences crystal phase stability.

Key Points

  • Improved hydrogen sensing performance is observed in WO3 films under varying interfacial stress.
  • The orthorhombic WO3 film exhibited a high electrical response of 1.97 × 10^4 toward 2% H2 at 80 °C.
  • Analysis of WO3 films grown on single-crystal substrates reveals critical relationships between stress and crystal phase.
  • These findings emphasize the potential of stress-engineered design for developing effective hydrogen sensors.
