Vertical Ferroelectric Field Effect Transistor Constructions, Constructions Comprising A Pair Of Vertical Ferroelectric Field Effect Transistors, Vertical Strings Of Ferroelectric Field Effect Transistors, And Vertical Strings Of Laterally Opposing Pairs Of Vertical Ferroelectric Field Effect Transistors

摘要

A vertical ferroelectric field effect transistor construction comprises an isolating core. A transition metal dichalcogenide material encircles the isolating core and has a lateral wall thickness of 1 monolayer to 7 monolayers. A ferroelectric gate dielectric material encircles the transition metal dichalcogenide material. Conductive gate material encircles the ferroelectric gate dielectric material. The transition metal dichalcogenide material extends elevationally inward and elevationally outward of the conductive gate material. A conductive contact is directly against a lateral outer sidewall of the transition metal dichalcogenide material that is a) elevationally inward of the conductive gate material, or b) elevationally outward of the conductive gate material. Additional embodiments are disclosed.
