Abstract
According to various embodiments, the present teachings include an array of nanowire devices. The array of nanowire devices comprises a readout integrated circuit (ROIC). An LED array is disposed on the ROIC. The LED array comprises a plurality of LED core-shell structures, with each LED core-shell structure comprising a layered shell enveloping a nanowire core, wherein the layered shell comprises a multi-quantum-well (MQW) active region. The LED array further comprises a p-side electrode enveloping the layered core-shell structure and electrically connecting the ROIC, wherein each p-side electrode has an average thickness ranging from about 100 nm to about 500 nm. A dielectric layer is disposed on the plurality of LED core-shell structures, with each nanowire core disposed through the dielectric to connect with an n-side semiconductor that is situated on the dielectric.
