- The work function is crucial for understanding electron behavior in materials, impacting corrosion rates and the development of photosensitive and electron-emitting devices.
- Various experimental methods, with a focus on Kelvin probe force microscopy (KPFM), are reviewed for measuring work functions, highlighting KPFM as the most effective technique.
- Computational methods like the stabilized Jellium model (SJM) and high-throughput density functional theory with machine learning (HTDFTML) are recommended for efficiently predicting work functions in complex materials, while maintaining lower costs.
In this study, five mathematical models were fitted in the absence of space charge with experimental data to find a more appropriate model and predict the emission current density of the graphene-based thermionic energy converter accurately. Modified Richardson Dushman model (MRDE) shows that TEC's electron emission depends on temperature, Fermi energy, work function, and coefficient of thermal expansion. Lowest Least square value of [Formula: see text] makes MRDE most suitable in modelling the emission current density of the graphene-based TEC over the other four tested models.

Films were grown via the wet-chemical electro-deposition technique and characterized for structural, optical, surface morphology, and photoluminescence (PL) properties. The X-ray Diffraction (XRD) result of the host matrix (pristine film) showed films of monoclinic structure with an average grain size of 36.
