Congratulations to E. Canberk Özçelik, who recently completed his master's degree on acoustic manipulation of spin qudits in 6H-SiC. He carried out his study at Leibniz University Hannover, and at PDI under the supervision of Alberto Hernández-Mínguez.

We are delighted to congratulate Xin Du, who received a student award for an outstanding presentation at the E-MRS Fall Meeting 2026, which took place Warsaw from September 14 to 17, 2026. Xin presented her work on “Stable Step-Flow Growth of Homoepitaxial AlN by Plasma-Assisted Molecular Beam Epitaxy” in Symposium E, Wide and ultra-wide-bandgap semiconductors challenges: from materials to applications.

LaInO₃ is emerging as a key substrate for boosting the electron mobility of the transparent conductive oxide BaSnO₃, yet its fundamental lattice dynamics had remained poorly characterized. This highlight covers new work from PDI, along with collaborators from the Leibniz-Institut für Kristallzüchtung (IKZ) and Swansea University, that combines polarization-resolved Raman spectroscopy with DFT calculations to deliver a complete symmetry-assigned map of the material's phonon modes.

Transition metal dichalcogenide monolayers (TMDCs) like WS₂ and MoS₂ are prized for their ability to efficiently double the frequency of light, but reported values for this effect vary wildly across studies using different substrates and conditions. This highlight covers new work that puts four TMDCs side by side on the same simple glass platform, situates the results against the existing literature, and delivers a self-consistent benchmark for choosing the right material for nonlinear photonic devices.
