We investigate the influence of infrared illumination using a free-electron laser on the photoluminescence of erbium-implanted silicon material. In addition to the earlier reported quenching of the Er-related photoluminescence due to dissociation of

The influence of intense infrared (IR) radiation in the range 7-17 μm on the photoluminescence (PL) of erbium in silicon has been investigated. To excite the PL a pulsed Nd:YAG laser operating in the visible with a wavelength of 532 nm has been used

Pysical review: B
Resonant polaron coupling has been observed by cyclotron resonance of two-dimensional electrons in the polar semiconductor InSe. Both upper and lower branches of the magnetopolaron are seen over a wide range of field (B=18--34 T), allowing an accurat

We present a review of magneto-optical experiments and theoretical calculations which have been used to examine the influences of dimensionality and many electron effects on electron-optic-phonon coupling in low dimensional structures of GaAs-(Ga,Al)

We have studied cyclotron resonance of the naturally occurring 2DEG found in the layered semiconductor InSe at magnetic fields up to 30 T. At low fields the resonances are split due to disorder. At higher fields we have observed resonant “polaron

In Er-doped silicon we have found direct evidence for the formation of the Er-related intermediate state that is a precursor of the final 4f-electron excited state responsible fur the 0.8 eV luminescence. Time-resolved photoluminescence following ban

We present an experimental observation of the magnetophonon effect in the frequency dependent conductivity of a GaAl-GaAlAs heterojunction. The cyclotron resonance position and linewidth are found to oscillate as a function of magnetic field and show

The resonant coupling of the subband-Landau-levels in the two-dimensional electron gas (2DEG) of high mobility GaAs-AlGaAs heterojunctions has been studied using cyclotron resonance (CR). When the applied magnetic field has a component in the plane o
