Application of 2D Materials in Photonic Sensing and Electronics

The materials that have enabled the information technology revolution over the past decades will soon reach their physical limits. Novel nanomaterials and technologies have therefore become a major focus of current solid-state device research, with two-dimensional (2D) materials being one of the most promising candidates. While much progress has been made on an individual device level, only a few studies have looked into more complex systems. In this talk I will present realizations of electronic and photonic systems, comprising a large number of 2D material-based devices. In particular, I will discuss photosensors that are able to simultaneously sense and process optical images without latency. We achieved both supervised and unsupervised learning and successfully trained the sensors to classify and encode images, that are optically projected onto the chip. Further, I will share our latest results on the heterogeneous integration of 2D materials with arbitrary substrates, including paper, for applications in electronics and integrated photonics. I will present investigations of 2D device variability, its physical origins, and how it affects system performance.
