Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.

Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon‐Enhanced Sum‐Frequency Microscopy

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
A nonlinear optical microscopy technique is introduced that enables rapid imaging of hexagonal boron nitride monolayers, which are usually optically invisible. The nonlinear mixing of mid‐infrared and visible laser pulses enables full crystallographic imaging through phase‐resolved sum‐frequency generation microscopy, where the resonant excitation of a
