Richardson Equation verification Apparatus
with power supply with 4 meters AE-1382A
When temperature - limited saturation current is collected at
the anode, Richardson's equation relating the thermionic
current density (Js) and the temperature of the cathode
(T°K) is written as
ln (Js / T2) = ln Ao - bo (l / T)
or log (ls / T2) = log AoS - 0.434 bo (l / t) ... (1)
A = AoS; bo = 11600Ew
Where ls = total saturation current,
S= total surface area of the emitting surface,
Ew = work function of the emitter
Ao = is a constant
Thus from the slope of the Richardson's line i.e. graph of log
(ls / T2) v/s (l / T), the work function Ew can be determined.
