Abstract
A two-terminal optoelectronic device includes a substrate having a first and a second series of grooves. A channel may transect the grooves of the first and second series of grooves. Each groove of the first and second series of grooves has a first and a second face and a cavity therebetween. The cavity is at least partially filled with a first semiconductor material. The first face is coated with a conductor material and the second face coated with a second semiconductor material. A structured surface of the substrate separates the first series of grooves from the second series of grooves to define a positive pole and a negative pole thereon. A method of producing an optoelectronic device incorporates the grooves into the surface of the substrate.
