description Semiconductor structures, devices, and methods that can exhibit various enhanced properties, such as, for example, enhanced light detection properties are provided. In one aspect, for example, an optoelectronic device can include a semiconductor material having an enhanced absorption region and a first defect in the enhanced absorption region, where the first defect is a deep-level defect generated by a first defect carrier type that is either a deep-level donor carrier type or a deep-level acceptor carrier type. The device can also include a second defect in the enhanced absorption region, where the second defect is either a shallow-level defect or a deep-level defect, and where the second defect is generated by a second defect carrier type that is opposite to the first defect carrier type. Furthermore, the enhanced absorption region has an external quantum efficiency of at least about 0.5% for electromagnetic radiation wavelengths greater than 1250 nm.
