Abstract Despite intensive investigations of Bi2Se3 in past few years, the size and nature of the bulk energy band gap of this well-known 3D topological insulator still remain unclear. Here we report on a combined magneto-transport, photoluminescence

We report on an infrared magneto-spectroscopy study of Pb$_{1-x}$Sn$_x$Se, a topological crystalline insulator. We have examined a set of samples, all in the inverted regime of electronic bands, with the tin composition varying from $x=0.2$ to $0.33$

III-V semiconductor mid-infrared photodetectors based on intersubband transitions hold a great potential for ultra-high-speed operation up to several hundreds of GHz. In this work we exploit a ~350nm-thick GaAs/Al 0.2 Ga 0.8 As multi-quantum-well het

We demonstrate a λ=10.3 μm Quantum Cascade Detector embedded in a subwavelength optical patch antenna cavity. In this structure, the responsivity is enhanced by the microcavity effect and the dark current is reduced thanks to the antenna effect. Th
