Optoelectronics using one and two dimensional materials

Abstract

Nanomaterial-enabled optoelectronic and sensing devices offer extraordinary advantages through their unique properties and functionalities. However, their performance levels are usually inadequate to meet the stringent demand for practical applications. An increasingly popular strategy to address these challenges is through the exploitation of computational algorithms in such devices. I will give specific examples of how nanomaterial-based devices could benefit from such approaches as the key enabler. The first example will be through the development of an ultraminiaturised computational spectrometer from a single nanostructure without complex optics or filters. I will then briefly discuss how the philosophy of mathematically combining the output of seemingly unconnected devices could be applied to more sophisticated designs, where active modulation of optoelectronic properties in a single device structure can enable even more miniaturised systems, representing a future application-agnostic platform with unmatched simplicity and compactness.
