Claim 9:
10. A semiconductor device, comprising:
a first transistor structure comprising:
a first channel structure surrounding a first dielectric core in a channel opening, the first channel structure comprising a first two-dimensional (2D) material and a second 2D material;
a first source metal surrounding a first portion of the first channel structure;
a first drain metal surrounding a second portion of the first channel structure;
a first gate metal surrounding a third portion of the first channel structure; and

a second transistor structure disposed above the first transistor and comprising:
a second channel structure surrounding a second dielectric core disposed above the first dielectric core in the channel opening, the second channel structure comprising a third 2D material and a fourth 2D material;
a second source metal surrounding a first portion of the second channel structure;
a second drain metal surrounding a second portion of the second channel structure;
a second gate metal surrounding a third portion of the second channel structure.
