A new simulation program is presented for focused ion beam (FIB) induced sputtering in two-dimensional targets. The model combines dynamic Monte Carlo simulation of the collision cascades with cell-based topography simulation. This approach takes the

Our recently developed simulation code FIBSIM is applied to topics related to transmission electron microscopy (TEM) sample preparation using focused ion beams (FIB). FIBSIM combines dynamic Monte Carlo simulation of collision cascades with two-dimen

The transition between coherent and incoherent transport in undoped $\mathrm{GaAs}/\mathrm{AlGaAs}$ superlattices is observed. Hot electron spectroscopy is used to measure the superlattice transmittance at different bias conditions. For a short-perio

Hot-electron spectroscopy in the presence of magnetic fields applied parallel to the current direction is studied. Inter-Landau-level transitions are observed due to scattering processes in the drift region of the hot-electron transistor. In high mag

The mean free path of hot electrons in GaAs/AlGaAs heterostructures is investigated. For the first time grating-induced Smith-Purcell emission is studied as a function of the grating period length. The mean free path is obtained from the changes in i

The drift velocity of hot electrons in AlGaAs/GaAs heterostructures is measured at different temperatures by a pulsed I‐V technique up to electric fields of 1.2 kV/cm. The experimental results are compared with theoretical drift velocities deduced

We present an efficient method — the variational mode‐matching (VMM) method — which preserves the advantages of mode‐matching techniques while increasing the numerical robustness significantly and providing the capability of local refinement.
