Abstract
Recent advances in heterogeneous integration technology have made it possible to combine multiple functionalities on a single system. Among various, combination of remote epitaxy and 2-dimensional later transfer (2DLT) techniques can produce freestanding single-crystalline membranes, such as III-V, III-N, and complex oxides. Based on this technology, various electronic and optoelectronic components can be fabricated and integrated. While it provides potential to build various devices on nearly any type of platform, integration of sensors and artificial synapses/neurons attracts great interest for the applications of artificial intelligence of things (AIoTs) by implementing for artificial neural networks (ANNs). Here, I will discuss how this advanced technology revolutionizes various sensors integrated with neuromorphic components for in- and near-sensor computing towards bio-inspired perception, recognition and reaction.
