Semiconductor junctions are present in all existing transistors, and transistors are the fundamental building blocks of modern electronic devices. A strongly doped device with the same type of doping in the channel area as the source and drain regions is known as a junctionless (JL) transistor. Chipmakers utilise junction-less transistors to build smaller devices. This work examines junctionless Double Gate (JL DG) MOSFETs with Threshold Voltage Roll-Off (TVR), DIBL, and Sub-threshold Swing.
