Research case study: Novel opto-electronic devices based on graphene plasmonics
"Atomically thin materials are enabling a new paradigm in ultra-sensitive light detection by leveraging on a unique selection of properties, thus allowing an expansion in the range of potential applications. For instance, these materials offer the ultimate lightweight solution for the creation of space-bound photodetectors, or wearable optoelectronic devices.
So far, the operational bandwidth of atomically thin heterostructure photodetectors is typically below 1 Hz, due to the presence of defects and disorder, which is too slow for many practical applications. Faster operational speeds have been demonstrated but these require the use of large gate voltage pulses, an extremely impractical strategy in highly integrated architectures.
To circumvent this limitation, we have encapsulated heterostructure photodetectors of tungsten disulphide (WS2) and graphene in an ionic polymer."
