Construction and operation of jet:
jet is a three terminal device one terminal capable of controlling the current between the other two. Basic construction of an n channel jet is in absence cue of any applied potential the jet has two p-n junctions under no bias condition. Depletion layer is void of free carriers and thereafter unable to support the conduction through the region. Gate applied potential control the flow of the chart from source to drain. Plot of id for various level of vs. can be shown.
Vx is controlling voltage of jet when is negative the characteristic obtained from different values of obtained as above.
