Enhanced thermionic emission from annealed CNT cathodes assessed via chaos-based electrical diagnostics

Key Points

• Enhanced thermionic emission was observed from CNT cathodes after annealing, highlighting a significant performance boost.
• Key measurements indicate a marked increase in emission current densities, particularly at elevated temperatures.
• Assessment using chaos-based electrical diagnostics effectively evaluated the performance characteristics of the cathodes.
• Findings suggest substantial implications for future electronic devices, with a focus on thermionic energy applications.
