I. S. Vasil’evskii

Hi Manish, please provide IV curve with several gating Ug.

Details are mainly sensitive to - source-drain length, gate length, HEMT layers composition.

Possible you have short channel effects or the gate placed on high doped contact layer.

L. Arivazhagan

send your result image (not saturating). Then I can see what is the problem . If I can , i will suggest some

Manish Verma

This is the image sir. Kindly suggest something.
