Sensitive Sub‐THz Photodetection in Twisted Graphene with Broad Spectral Response

Advanced Science, Volume 12, Issue 46, December 11, 2025.
A dual‐gated twisted monolayer–bilayer graphene (TMBG) phototransistor enables ultrabroadband detection spanning visible to sub‐THz regimes. Gate‐tunable moiré bands produce photothermoelectric responses at zero bias and bolometric responses under applied bias.

Dislocations in twistronic heterostructures

2D Materials
Abstract Long-period moiré superlattices at the twisted interface of van der Waals heterostructures relax into preferential stacking domains separated by dislocation networks. Here, we develop a mesoscale theory for dislocations in networks formed in twistronic bilayers with parallel (P) and antiparallel (AP) alignment of unit cells ...
