Transistors including two-dimensional materials

A microelectronic structure, comprising:

• a transistor, including:
• a channel, wherein the channel includes a first two-dimensional material, and
• a region, wherein the region is one of a source region and a drain region of the transistor, the region includes a second two-dimensional material, and the second two-dimensional material is a single-crystal two-dimensional material.

An electronic device, comprising:

• an integrated circuit (IC) die including a microelectronic structure, wherein the microelectronic structure includes a transistor, the transistor includes a first two-dimensional material in a channel, the transistor includes a second two-dimensional material in a region that is one of a source region and a drain region of the transistor, wherein the first two-dimensional material is a single-crystal material, and the second two-dimensional material is a single-crystal material;
• and
• a circuit board, wherein the IC die is coupled with the circuit board.
