Abstract This work presents the design and performance analysis of a tri-layered strained Si/Si 1− x Ge x /Si heterostructure double gate feedback field-effect transistor (DG FBFET). The proposed DG FBFET is designed by introducing biaxial strain in the device by sandwiching a Si 1− x Ge x layer between two thin Si layers to provide high ON current as well as ultra-steep switching characteristics. The device offers a significantly high ON current (3.4 x 10 −3 A/ μ m), high I ON / I OFF ratio (∼10 10 ), a large memory window of 1.06 V, and an extremely low subthreshold swing (∼0.3 μ V/decade), which can be very useful for memory and neuromorphic applications. Furthermore, the ON/OFF switching of the device has been accomplished at a lower threshold voltage (0.287 V), allowing it to be utilized in low-power electronics. Synopsys TCAD tool has been used to create the device structure and analyze the electrical performances of the device.
