Chemical sensing with switchable transport channels in graphene grain boundaries

Grain boundaries in graphene are present between misaligned crystalline areas, and influence the resulting properties, often in a negative fashion. Here, the authors use these boundaries for chemical detection, observing markedly higher sensitivities as compared with single-crystalline domains.
