A THz quantum cascade detector in a strong perpendicular magnetic field

Giacomo Scalari, Marcel Graf, Daniel Hofstetter, Jérôme Faist, Harvey Beere & David Ritchie

Résumé A 3.6 THz quantum cascade detector is studied under the influence of a strong magnetic field applied perpendicularly to the plane of the layers. Modulation of lifetimes based on elastic intersubband scattering processes is observed, leading to an increase of the responsivity for particular values of the applied magnetic field.
