Current responsivity of semiconductor superlattice THz-photon detectors
Anatoly A. Ignatov, Antti-Pekka Jauho
The current responsivity of a semiconductor superlattice THz-photon detector is calculated using an equivalent circuit model which takes into account the finite matching efficiency…
Angle dependence of Andreev scattering at semiconductor-superconductor interfaces
Niels Asger Mortensen, Karsten Flensberg, Antti-Pekka Jauho
We study the angle dependence of the Andreev scattering at a semiconductor-superconductor interface, generalizing the one-dimensional theory of Blonder, Tinkham and Klapwijk. An in…
Excitonic Dynamical Franz-Keldysh Effect
K. B. Nordstrom, K. Johnsen, S. J. Allen +6
The Dynamical Franz-Keldysh Effect is exposed by exploring near-bandgap absorption in the presence of intense THz electric fields. It bridges the gap between the DC Franz- Keldysh…
