THz Higher-Order Topological Photonics in Ge-on-Si Heterostructures
Ian Colombo, Pietro Minazzi, Emiliano Bonera +2
We design germanium-based higher-order topological cavities for terahertz applications by breaking the symmetry of a two-dimensional photonic crystal following the Su-Schrieffer-He…

Metal Droplet Effects on the Composition of Ternary Nitrides
Mani Azadmand, Stefano Vichi, Sergio Bietti +7
We investigate effects of metal droplets on the In incorporation in InGaN epilayers grown at low temperature (450 C) by plasma assisted molecular beam epitaxy. We find a strong red…
