Advanced Optical Materials, EarlyView.Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells
Advanced Optical Materials, EarlyView.We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Excitonic Landscapes in Monolayer Lateral Heterostructures Revealed by Unsupervised Machine Learning
Advanced Optical Materials, EarlyView.Hyperspectral photoluminescence data from graded MoxW1 − xS2 alloys and monolayer MoS2–WS2 lateral heterostructures are analyzed using unsupervised machine learning. The combined use of PCA, t‐SNE, and DBSCAN uncovers distinct excitonic regions that trace how composition, strain, and defects modulate optical responses in these 2D materials.
