This paper investigates a novel design of penternary logic gates usingcarbon nanotube field effect transistors (CNTFETs). CNTFET is a suitable candidate forreplacing MOSFET with some useful properties. such as the capability of having thedesired threshold voltage by regulating the diameter of the nanotubes. Multiple-valuedlogic (MVL) such as ternary. https://chefesquipmenters.shop/product-category/cutters/
