We present measurements of electron cooling times in `quasi' quantum wires and dots as a function of the z-confinement. The states were created by application of a magnetic field along the growth direction of bulk material, a wide parabolic well and

Landau-level lifetimes are determined from saturation cyclotron resonance (CR) in wide parabolic wells, quantum wells and bulk PbTe-Pb1-xEuxTe systems. These narrow gap structures exhibit strong band non-parabolicity necessary to terminate the normal

We review the methods that have been used for suppressing non-radiative processes in mid-infrared (MIR) semiconductor lasers and detectors. Specifically we discuss the results of techniques that have been used recently to minimise the deleterious eff

The band alignments and band offsets were investigated for In(As,Sb)/InAs superlattices of various periods and compositions. Magnetoabsorption experiments allowed identification of subband energies and in-plane reduced masses. Using an 8\ifmmode\time

The growth and evaluation of InAs/GaSb/AlSb quantum wells and InAs, -,Sb,/InAs strained layer superlattices are discussed. A characteristic of the InAs/GaSb/AISb combinations is their high mobility and the applications are mainly concerned with optim

Room-temperature pump-probe transmission experiments have been performed on an arsenic-rich InAs/InAs1-xSbx strained layer superlattice (SLS) above the fundamental absorption edge near 10 mu m, using a ps far-infrared free-electron laser. Measurement

Picosecond excitation‐probe measurements using a far‐infrared free‐electron laser (CLIO) have revealed large nonlinearities for indium antimonide at 4.7 μm. A theoretical model is described to determine the cw third‐order nonlinear susceptib

Pump-probe transmission experiments have been performed on PbSe above the fundamental absorption edge near 4 μm in the temperature range 30 to 300 K, using the Dutch ps free-electron laser. For temperatures below 200 K and carrier densities above th

Picosecond time-resolved far-infrared measurements are presented of the scattering between conduction-band states in a doped quasi quantum dot. These states are created by the application of a magnetic field along the growth direction of an InAs/AlSb

A direct measurement of carrier recombination, far from equilibrium, in Hg0.795Cd0.205Te (N-d - N-a = 3.3 X 10(14) cm(-3)) has been made on a picosecond time scale with a pump-probe technique using a free-electron laser. Over the range of carrier den
