3D Nanoscale Mapping of Short-Range Order in GeSn Alloys
Shang Liu, Alejandra Cuervo Covian, Xiaoxin Wang +5
GeSn on Si has attracted much research interest due to its tunable direct bandgap for mid-infrared applications. Recently, short-range order (SRO) in GeSn alloys has been theoretic…

Wide band gap phase change material tuned visible photonics
Weiling Dong, Hailong Liu, Jitendra K Behera +6
Light strongly interacts with structures that are of a similar scale to its wavelength; typically nanoscale features for light in the visible spectrum. However, the optical respons…

Inter-diffusion of Plasmonic Metals and Phase Change Materials
Li Lu, Weiling Dong, Jitendra K. Behera +2
This work investigates the problematic diffusion of metal atoms into phase change chalcogenides, which can destroy resonances in photonic devices. Interfaces between Ge2Sb2Te5 and…
