Through phonon band structure engineering, we reduced TBR in GaN/BAs interfaces by over 8-fold compared to GaN/diamond interfaces. The combination of low TBR and high thermal conductivity ...

Phonon-polaritons are a unique type of electromagnetic wave that occurs when light interacts with vibrations in a material's crystal lattice structure. These phonon-polariton waves exhibit several ...

Unexpected mobility in the moiré seascape Raja's lab focuses on characterizing 2D materials using ultrafast lasers and optical spectroscopy at temperatures below -150°C. Exciting the layered TMD ...
