Quantum dot admittance probed at microwave frequencies with an on-chip resonator
T. Frey, P. J. Leek, M. Beck +5
We present microwave frequency measurements of the dynamic admittance of a quantum dot tunnel coupled to a two-dimensional electron gas. The measurements are made via a high-qualit…
Direct surface cyclotron resonance terahertz emission from a quantum cascade structure
François-Régis Jasnot, Louis-Anne De Vaulchier, Yves Guldner +6
A strong magnetic field applied along the growth direction of a semiconductor quantum well gives rise to a spectrum of discrete energy states, the Landau levels. By combining quant…
Room temperature terahertz polariton emitter
Markus Geiser, Giacomo Scalari, Fabrizio Castellano +2
The strong-coupling regime between an electronic transition and the photonic mode of a optical resonator manifests itself in the lifting of the degeneracy between the two modes and…
