Near-field Hyperspectral Imaging of Resonant Mie Modes in a Dielectric Island
Nicoletta Granchi, Michele Montanari, Andrea Ristori +8
All-dielectric, sub-micrometric particles have been successfully exploited for light management in a plethora of applications at visible and near-infrared frequency. However, the i…
THz intersubband electroluminescence from n-type Ge/SiGe quantum cascade structures
David Stark, Muhammad Mirza, Luca Persichetti +15
We report electroluminescence originating from L-valley transitions in n-type Ge/SiGe quantum cascade structures centered at 3.4 and 4.9 THz with a line broadenin…
Intersubband transition engineering in the conduction band of asymmetric coupled Ge/SiGe quantum wells
Luca Persichetti, Michele Montanari, Chiara Ciano +9
: n-type Ge/SiGe asymmetric-coupled quantum wells represent the building block of a variety of nanoscale quantum devices, including recently proposed designs for a silicon-based TH…
Atomic-scale insights into semiconductor heterostructures: from experimental three-dimensional analysis of the interface to a generalized theory of interface roughness scattering
T. Grange, S. Mukherjee, G. Capellini +8
We develop a generalized theory for the scattering process produced by interface roughness on charge carriers and which is suitable for any semiconductor heterostructure. By exploi…
Photoluminescence study of interband transitions in few-layer, pseudomorphic, and strain-unbalanced Ge/GeSi multiple quantum wells
M. Montanari, M. Virgilio, C. L. Manganelli +11
In this paper we investigate the structural and optical properties of few strain-unbalanced multiple Ge/GeSi quantum wells pseudomorphically grown on GeSi reverse-graded substrates…
