NOVELTY - Transistor comprises a channel that comprises a two-dimensional material adjacent to a seed material, the channel oriented perpendicular to a base material, a gate dielectric adjacent to the two-dimensional material, and gates adjacent to the gate dielectric. USE - Transistor. ADVANTAGE - The transistor improves crystalline quality. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a memory cell which comprises transistors, in which transistors comprises: i. an L-shaped channel comprising a two-dimensional material; ii. an insulative material and a gate dielectric adjacent to the L-shaped channel; iii. a gate adjacent to the gate dielectric and capacitor in operative communication with the transistor; (2) a semiconductor device which comprises an array of memory cells, in which memory cells comprises: a. transistors comprising L-shaped portions of a two-dimensional material exhibiting a width of from about one monolayer of atoms to about three monolayers of atoms; b. dielectric material separating the L-shaped portions of the two-dimensional material; c. gate dielectric laterally adjacent to the L-shaped portions of the two-dimensional material; d. gates adjacent to the gate dielectric; and e. capacitors in operative communication with the transistors.
