Physiological studies of the rodent somatosensory cortex have consistently described considerable heterogeneity in receptive field properties of neurons outside of layer IV, particularly those in layers V and VI. One such approach for distinguishing

Free-standing GaN substrates of up to 2″ diameter can be produced by delamination of thick HVPE (hydride vapour phase epitaxy) films from sapphire with a laser-induced liftoff process. Homoepitaxial films of up to 2 μm thickness were grown on the

Interference patterns from overlapping beams of an intense pulsed laser are used to realize high-resolution thermal processing for direct structuring of semiconductor films. Line and dot arrays have been realized, with periods down to 130 nm. In AlGa

The Raman-scattering intensity of C${}_{60}$ intramolecular modes in fullerite, excited at 2.41 eV, strongly increases (up to one order of magnitude) upon cooling below room temperature. The effect has different strength for the ${A}_{g}$ and ${H}_{g

We report Raman spectroscopy studies for ${\mathrm{Rb}}_{3}$${\mathrm{C}}_{60}$ films, which have been grown and measured, in situ, in an ultrahigh-vacuum chamber. We find interesting dependences of some of the vibrational modes on the excitation ene

Using rotating analyzer ellipsometry, we determined at room temperature and at 30 K the doping dependence of the ${\mathit{E}}_{1}$ and ${\mathit{E}}_{1}$+${\mathrm{\ensuremath{\Delta}}}_{1}$ critical points of n-type highly Si-doped GaAs(100) (up to

Spectroscopic ellipsometry has been employed in the far-infrared range 100-650 cm- ~ to determine the frequency-dependent complex dielectric constant and conductivity of a thin film of YBa2Cu307 as a function of temperature between 20 and 300 K with

Optical spectra for ${\mathrm{C}}_{60}$ films, obtained by elliposmetry, are reported for the energy range from 1.9 to 9.5 eV. Our results are compared with related results from other optical techniques as well as photoemission results. Strong simila

The dielectric tensor elements of oriented YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} samples, as obtained by spectroscopic ellipsometry, are presented for several oxygen stoichiometries in the photon energy range between 1.66 and 5.5 eV. For {delta}=
