Herein, the authors suggest a junctionless field effect transistor with an embedded p‐type layer (EPL‐JLT) near the drain channel side, employing calibrated structure simulations to obtain a complete depletion region in a 6 nm channel length. The incorporation of a p‐type layer improves leakage current (I
OFF) and subthreshold swing (SS) for a 6 nm regime structure at 5.9 eV work function (WF) while the ON current (I
ON) diminishes a little. This considerable achievement in the leakage current enables obtaining multiple threshold voltages (V
TH) by adjusting the gate WF. The goal aids in creating optimized structures, which is impossible in silicon JLFETs (Si‐JLT) due to their requirement for large WFs to obtain a depletion region even at higher channel lengths. The proposed device has a leakage current of 1 nA μm−1 even at a 5.1 eV WF. The scaling of the EPL‐JLT for different channel lengths is investigated.
