It has been demonstrated that it is possible to grow by molecular beam epitaxy bulk free-standing zinc-blende (cubic) GaN layers. Such layers have potential applications as lattice matched substrates for growth of non-polar cubic GaN device structure

We have used bolometric detection techniques to study the phonons generated by ultrafast optical excitation of a gallium nitride/aluminium nitride superlattice (SL) structure. For excitation wavelengths shorter than 435 nm, we observe a strong longit

We have investigated the effect of the internal electric fields on radiative and non-radiative processes in a series of AlN/GaN superlattices. The results of measurements involving direct detection of phonons emitted as a result of non-radiative reco

We describe an electrically pumped sound amplification by stimulated emission of radiation (SASER) device for terahertz frequencies. The gain medium of the device is a weakly coupled AlAs/GaAs superlattice (SL). It is incorporated into a multimode ac

We have used the heat pulse technique to study phonon transport in 6H–silicon carbide. We have directly detected ballistic acoustic phonons which have propagated across the substrate and have observed the arrival of phonons multiply reflected from

We have used a combination of heat pulse phonon and luminescence measurements to study the recombination dynamics in an optically excited MBE-grown GaAsN film. We observed that the blue (EPL=2.5 eV) photoluminescence decay in the GaAsN alloy possesse

We have used phonon imaging to study the drag current induced by non-equilibrium acoustic phonons in a low-mobility n-type Gallium Nitride epilayer. Current densities up to j=4.7×10 3 A/m 2 were induced by transverse acoustic phonon drag of electron

The rate of energy loss per electron, P e , by a two-dimensional electron gas in an GaN/AIGaN heterostructure has been measured as a function of electron temperature, T e , in the range 0.4-35 K. A combination of zero and high magnetic field electric
