Abstract
An optical transducer, optoelectronic device, and semiconductor are disclosed. An illustrative optical transducer is disclosed to include a plurality of p-n stacks, where each p-n stack comprises at least a p-layer and an n-layer, and formed therein a built-in photovoltage between the p-layer and the n-layer. The p-layers and n-layers are disclosed to have substantially the same n-type material in substantially the same composition such that each p-n stack in the plurality of p-n stacks has a substantially similar built-in photovoltage. The optical transducer is further disclosed to include a plurality of connecting layers, each connecting layer in the plurality of connecting layers being sandwiched between two adjacent p-n stacks for electrically connecting the two adjacent p-n stacks. The p-n stacks in the plurality of p-n stacks may be arranged such that the built-in photovoltage of each p-n stack additively contributes to an overall electric potential of the transducer.
