Semiconductor film and field effect transistor having semiconductor and polymer portions stacked adjacent each other
The present invention provides a semiconductor film, a field effect transistor, and a method of fabricating the semiconductor film that has one or two or more semiconductor portions, which are formed from a semiconductor material, and one or two or more polymer portions, which are formed from a polymer material. The semiconductor portion and the polymer portion are adjacent to each other and are integrated.
1. A semiconductor film comprising:
a semiconductor portion that is formed from an organic semiconductor material and comprises crystals and has a width of 1 mm or more; and
a polymer portion that is formed from a polymer material, wherein:
each of the semiconductor portion and the polymer portion has a layer shape, and the semiconductor portion and the polymer portion are stacked adjacent to each other in a stacking direction,
an angle between orientation axes of the crystals is 10 degrees or less, and
each crystal has a length of 200 μm or more.
2. The semiconductor film according to claim 1 , wherein the semiconductor portion is a single crystal.
3. A field effect transistor comprising the semiconductor film according to claim 1 .
