This cover image showcases a flexible thermoelectric generator with outstanding power output, utilizing gold-decorated black phosphorus (BP). In article number 1800532, Song Yun Cho and co-workers highlight how surface decoration with gold nanoparticles can finely tune the electronic and thermoelectric properties of exfoliated BP. Notably, the air stability of BP is significantly enhanced as the gold nanoparticles occupy its energetic defects. – Journal cover design by scapiens
