Abstract: The present invention relates to a carbon nanotube organic semiconductor, a manufacturing method thereof, and a thin film transistor for chemical sensor using the same. More specifically, the present invention provides a carbon nanotube organic semiconductor, a manufacturing method thereof, and a thin film transistor for chemical sensor using the same, where the carbon nanotube organic semiconductor is an organic semiconductor layer constituting an organic thin film transistor and comprising a conjugated polymer and a single-walled carbon nanotube, the single-walled carbon nanotube displaying semiconducting properties and being wrapped with the conjugated polymer.

Abstract: The present invention relates to a carbon nanotube interlayer, a manufacturing method thereof, and a thin film transistor using the same. More specifically, the present invention provides a carbon nanotube interlayer, a manufacturing method thereof, and a thin film transistor using the same, where the carbon nanotube interlayer is a layer constituting an organic thin film transistor and comprising a conjugated polymer and a single-walled carbon nanotube between an organic semiconductor layer and a source/drain electrode. The conjugated polymer selectively wraps the single-walled carbon nanotube having semiconducting properties.
