研究目的
Investigating the performance of optically controlled organic field effect transistors based on a binary mixture of fullerene C60 and spiropyran as the active layer compared to multilayer transistors.
研究成果
The designed OFETs with active layers based on fullerenes and spiropyran exhibit high charge carrier mobility, photosensitivity, and responsivity, making them suitable for optical memory cells, optrons, and photosensors. Their manufacturing process is compatible with modern printed organic electronics technology.
研究不足
The study highlights the advantages of mixed-layer transistors over multilayer ones but does not explore the long-term stability or scalability of these devices for industrial applications.
1：Experimental Design and Method Selection:
The study involved the fabrication of optically controlled OFETs with either a binary mixture of fullerene C60 and spiropyran or separate layers of these materials as the active layer.
2：Sample Selection and Data Sources:
The active layers were prepared by thermal vacuum deposition from a Knudsen cell.
3：List of Experimental Equipment and Materials:
A glass substrate with a conducting indium tin oxide (ITO) layer as the gate, polyaniline (PANI) as the gate dielectric, and aluminum electrodes for drain and source.
4：Experimental Procedures and Operational Workflow:
The films were deposited at 300 °C, with aluminum electrodes deposited by thermal sputtering.
5：Data Analysis Methods:
The charge carrier mobility was estimated from the current-voltage characteristics, and the response to UV light was measured.
