In this study, we have investigated the deviation of the electron emission properties from the (011), (111), (121), and (112) facets of the tungsten needle, and examined the validity of our interpretation. It was confirmed that a linear distribution of the F-N characteristics in the S-K chart is under the constant work function, and its slope is proportional to the three halves power of the work function. The Seppen-Katamuki analysis provides a simple, precise, and quick estimation of work function of the field emission device
