The luminescence decay times are measured taking into account reabsorption for KY(WO4)2:Yb(KYW:Yb) crystals with atomic concentrations of active ions from 0.2% to 30%. The radiative lifetime of Yb3+ ions was measured to be 233 μs. The cw output powe

Multiple quantum well (MQW) p-i-n heterostructures are a new alternative to increase the quantum efficiency of solar cell devices. In such structures, the QW carrier capture, carrier escape and radiative recombinations are the phenomena governing the

A near-field pump-probe system with nanometer-scale spatial and femtosecond temporal resolution allows us to measure complex spatiotemporal carrier diffusion dynamics in semiconductor nanostructures. Single ${\mathrm{G}\mathrm{a}\mathrm{A}\mathrm{s}/

We have studied the coherent emission from bulk semiconductors by spectrally resolved and spectrally integrated four-wave mixing (FWM) with broadband 16-fs pulses in the carrier density range from $1\ifmmode\times\else\texttimes\fi{}{10}^{16}{\mathrm

Investigating the ternary InxGa1−xAs alloy (x ∼ 12%) by cross-sectional scanning tunneling microscopy, we find that on the UHV-cleaved (110) surface the In distribution in both the surface and the first subsurface layer can be atomically resolved

During the past year, the broad tunability (1-10 mum) and megawatt peak intensity made available by the Vanderbilt Free-Electron Laser opened new and productive avenues to semiconductor research. This paper overviews three of these experimental areas
