Terahertz saturable absorbers from liquid phase exfoliation of graphite

Nature Communications, 2017
Graphene shows promise for saturable absorption, a key property for ultrafast lasing, yet graphene saturable absorbers operating in the terahertz region suffer from low absorption modulation.

Strain-engineered inverse charge-funnelling in layered semiconductors

Nature Communications, 2018
The application of strain to semiconducting materials can be used to engineer electric fields through a varying energy gap. Here, the authors observe an inverse charge-funnel effect in atomically thin HfS2, enabled by strain-induced electric fields.
