Graphene-based mid-infrared room-temperature pyroelectric bolometers with ultrahigh temperature coefficient of resistance

Sassi, U., et al. Nature Communications 2017 DOI: 10.1038/ncomms14311

This work reports the use of graphene as part of an uncooled, mid-infrared photodetector, where the pyroelectric response of a LiNbO3 crystal is transduced with high gain (up to 200) into resistivity modulation for graphene. The nanoETCH system is critical as part of the work, being used to both etch the graphene into required patterns and for modifying single sheets in order to provide for ultra-low contact resistances.
