Materials that exhibit a low work function and therefore easily emit electrons into vacuum form the basis of electronic devices used in applications ranging. Web the work functions of tungsten and sodium are 5.06 ev and 2.53 ev respectively. If threshold wavelength of sodium is 5896 a˚ , then the threshold wavelength of tungsten. Web what is work function? It enhances emission efficiency of cathode tube. Web the bare work function values agree with known experimental values placing the polycrystalline w work function at about 4.6 ev. Measurements of the thermionic work function of pure tungsten have been made by two methods for the same segment of a uniformly heated filament. Web throughout the present work, however, tungsten has been used as the substrate for the following reasons: The incident energy is used in. Web research shows that thorium tungsten alloy working function is 2.66ev, 40% lower than pure tungsten.
