Layer structures including configuration increasing operation characteristics, methods of manufacturing the same, electronic devices including layer structures, and electronic apparatuses including electronic devices

An electronic device comprising:

• a substrate;
• a first electrode on the substrate;
• a second electrode on the substrate and separated from the first electrode;
• a gate electrode on the substrate and separated from the first electrode and the second electrode;
• a channel layer connected to the first electrode and the second electrode, the channel layer separated from the gate electrode;
• and
• a stressor layer on the channel layer is a strain-inducing layer,
• wherein the channel layer has a trace of applied strain,
• wherein the channel layer comprises a two-dimensional material,
• wherein a thickness of the stressor layer is greater than a thickness of the channel layer, and
• wherein the channel layer, the gate electrode, and the stressor layer vertically overlap each other.
