Experiments have shown that ultrafast optical excitation of semiconductors can produce oscillating changes in the optical properties of the material. The frequency of the oscillations in transmission or reflection usually matches one of the phonon modes, typically the q = 0 optical mode. These oscil

We present the first measurements of the effect of nonequilibrium phonons on the tunnel current in a weakly coupled GaAs/AlAs superlattice. The phonon-induced current has a maximum at a bias voltage which varies linearly with phonon source temperature at both zero and applied magnetic fields (B = 6

This paper presents Monte Carlo simulations of the positron diffusion process in a solid grain when an external magnetic field is applied. Our work has focused on the fraction of positrons, which reach the grain boundary because such a parameter can be observed in positron experiments. The simulatio
