Claims51
An electronic device comprising:
- a first semiconducting polymer film, which includes mono-substituted diphenylhydrazone (DPH), electrically coupled to both a first electrical contact and a second electrical contact.
An electronic device comprising:
- a first electrical contact and a second electrical contact;
- and
- a first semiconducting polymer layer including p-(diethylamino) benzaldehyde diphenylhydrazone (DEH) electrically coupled to said first electrical contact, and said second electrical contact.
An electrically addressable device comprising:
- a first semiconducting polymer film, which includes mono-substituted diphenylhydrazone (DPH), having a first side and a second side;
- a first plurality of electrical conductors substantially parallel to each other in contact with said first side of said semiconducting polymer layer;
- and
- a first plurality of ultraviolet transmitting electrical conductors substantially parallel to each other, in contact with said second side of said first semiconducting polymer layer and substantially mutually orthogonal to said first plurality of electrical conductors.
A method of fabricating an electronic device comprising the step of creating a first electrical contact and a second electrical contact on a a first semiconducting polymer film, which includes mono-substituted diphenylhydrazone (DPH),
A method of manufacturing an electrically addressable device comprising the steps of:
- creating a first semiconducting polymer film, which includes mono-substituted diphenylhydrazone (DPH), having a first side and a second side;
- creating a first plurality of electrical conductors substantially parallel to each in contact with said first side of said first semiconducting polymer layer;
