研究目的
To investigate the ionic conduction response under extending deformation of a silver iodide (AgI) thin film.
研究成果
The ionic conductivity of β-AgI thin films decreases and the activation energy increases with increasing extension ratio, attributed to the deformation of the crystalline framework. Future research will explore ionic conduction perpendicular to the tensile direction and the Liang effect in these films.
研究不足
The study focused on ionic conduction in the direction parallel to the tensile direction; the response perpendicular to the pulling direction was not investigated. Additionally, the Liang effect in AgI thin films on PET substrates was suggested but not studied in detail.
1：Experimental Design and Method Selection:
The study involved applying tensile stress to β-AgI thin films prepared on polyethylene terephthalate (PET) films and investigating the ion conduction response.
2：Sample Selection and Data Sources:
AgI thin films were fabricated on PET films by vacuum deposition and reaction with iodine.
3：List of Experimental Equipment and Materials:
Equipment included a 3D microscope (OLS4000 LEXT, Olympus Co., Ltd.), X-ray diffractometer (RINT2100/PC, Rigaku Co., Ltd.), and impedance analyzer (HP4194A, Hewlett Packard). Materials included PET films and AgI.
4：Experimental Procedures and Operational Workflow:
The process involved fabricating AgI thin films, applying tensile stress, and measuring impedance under controlled conditions.
5：Data Analysis Methods:
The DC resistivity was estimated from impedance measurements, and activation energy was calculated using a thermal-activation formula.
