Polymorphism Crystal Structure Prediction with Adaptive Space Group Diversity Control

Advanced Science, EarlyView.
Polymorphic materials exhibit diverse properties despite identical compositions, but predicting their crystal structures remains challenging. This study introduces ParetoCSP2, a multi‐objective genetic algorithm incorporating genotypic age, energy, and space group diversity.

High‐Temperature Single‐Photon Emission From Covalently Functionalized van der Waals Heterostructures

Advanced Science, EarlyView.
Covalent diazonium functionalization of graphite‐WSe2 heterostructures produces high‐purity single‐photon emission from WSe2 at T = 90 K, far above the typical T = 10 K limit. The chemical modification reshapes graphite's electronic structure and couples to WSe2 midgap states, stabilizing quantum emitters at elevated temperatures and opening pathways ...

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

Advanced Science, EarlyView.
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.
