Universal Features of Terahertz Absorption in Disordered Materials
S. N. Taraskin, S. I. Simdyankin, S. R. Elliott +2
Using an analytical theory, experimental terahertz time-domain spectroscopy data and numerical evidence, we demonstrate that the frequency dependence of the absorption coupling coe…

Ultra low threshold current THz quantum cascade lasers based on buried strip-waveguides
S. Dhillon, J. Alton, S. Barbieri +5
THz quantum cascade lasers based on a novel buried cavity geometry are demonstrated by combining double-metal waveguides with proton implantation. Devices are realised with emissio…

Unusual conductance collapse in one-dimensional quantum structures
KJ Thomas, DL Sawkey, M Pepper +4
We report an unusual insulating state in one-dimensional quantum wires with a non-uniform confinement potential. The wires consist of a series of closely spaced split gates in high…
