text: The synthesis and characterization of ordered mesoporous In2O3 materials by
structure replication from hexagonal mesoporous SBA-15 silica and cubic KIT-6
silica is presented. Variation of the synthesis parameters allows for different
pore sizes and pore wall thicknesses in the products. The In2O3 samples turn out
to be stable up to temperatures between 450 °C and 650 °C; such high thermal stability
is necessary for their application as gas sensors. Test measurements show a high
sensitivity to methane gas in concentrations relevant for explosion prevention.
The sensitivity is shown to be correlated not only with the surface-to-volume
ratio, but also with the nanoscopic structural properties of the materials.

text: We report a systematic study of the photoluminescence properties of ZnO nanostructures.
In particular, mesoporous ZnO powders of varying surface-to-mass ratio are investigated
and compared to a bulk reference. At low temperatures the emission from higher-energy
states is very pronounced and even dominant for samples with high surface-to-mass
ratio.

text: We demonstrate a technique for the generation and detection of electron currents
at surfaces on a femtosecond time scale with a contact-free experimental setup
based on a combination of coherent control and photoemission spectroscopy. We
have applied this technique for electrons excited into image-potential states
on a Cu(100) surface that form a free-electron-like band in the direction parallel
to the surface. The photogeneration of currents is described by optical Bloch
equations for a multiband model. By incorporating field-induced interband and
intersubband transitions together with intraband accelerations into the model,
the observed phase dependence of the population and of the current can be reproduced.

text: We present the preparation of a semiconductor gas sensor based on ordered
mesoporous In2O3. The In2O3 was synthesized by structure replication procedure
from cubic KIT-6 silica. A detailed analysis of the morphology of the mesoporous
powders as well as of the prepared sensing layer will be shown. Unique properties
arise from the synthesis method of structure replication such as well defined
porosity in the mesoporous regime and nanocrystallites with high thermal stability
up to 450 °C. These properties are useful for the application in semiconducting
gas sensors. Test measurements show sensitivity to methane gas in concentrations
relevant for explosion prevention.

text: Halbleitende Metalloxid-Gassensoren werden sowohl im industriellen Bereich
als auch im Haushalt zur Luftüberwachung verwendet. Die Funktionsweise basiert
auf einer reversiblen Änderung des Sensorwiderstandes in Anwesenheit sowohl oxidierender
als auch reduzierender Gase, die mit einfachen Mitteln gemessen werden kann. In
diesem Artikel wird vorgestellt, wie sich die bei der Gasdetektion ablaufenden
Vorgänge mit Hilfe des Ionosorptionsmodells in Kombination mit einem einfachen
Festkörperbändermodell deuten lassen. Abschließend werden einfache, im Chemieunterricht
zu realisierende Experimente mit Gassensoren präsentiert.

text: Recently it has been shown experimentally that it is possible to coherently
control nano-optical excitations by using sophisticated shaped laser pulses. In
this work a similar technique is used to theoretically investigate a hybrid nanostructure
which consists of a metal aperture and a quantum wire. It is shown that one can
concentrate the optically excited electron density at an arbitrary position due
to wave packet dynamics by chosing particular frequency components and phases
of the chirped laser pulse. The optimization process is performed with a genetic
algorithm which is linked to a 3D-FDTD solver.

text: A one-dimensional semiconductor nanostructure is locally excited through a
metal aperture. It is shown that the electron density can be coherently localized
at desired spatial and temporal positions by using nontrivially shaped laser pulses.
To obtain the optimized laser field, Bloch equations for a tight-binding model
system are solved together with a genetic pulse-shaping algorithm. Full three-dimensional
finite-difference time-domain (FDTD) simulations of the Maxwell–Bloch equations
confirm the predicted coherent spatiotemporal control.

text: We have experimentally investigated injection currents generated by all-optical
excitation of GaAs/AlGaAs quantum wells excited with 130 fs optical pulses. The
currents have been detected via free-space THz experiments at room temperature.
Our experiments prove that Coulomb effects strongly influence injection currents.
This becomes most prominently visible when exciting light-hole exciton transitions.
At this photon energy we observe a pronounced phase shift of the current transients
which is due to oppositely oriented heavy-hole and light-hole type contributions.
We are currently developing a microscopic theory based on a 14×14 k.p model in
combination with the semiconductor Bloch equations to describe the observed features
quantitatively. The combined theoretical and experimental approach will allow
us to analyze the influence of the bandstructure and interaction effects on the
injection current amplitude and current dynamics.

text: The paper presents a theoretical analysis of the nonlinear THz response from
the internal transitions of coherent and incoherent excitons based on the formulated
microscopic THz theory. Moreover, the response of unexcited semiconductors to
extremely intense THz fields is investigated .The intersubband transitions of
optically excited quantum wells using linear THz spectroscopy is also studied.
The computed differential transmission shows a characteristic Fano-like line shape
of the intersubband resonance. The pure intersubband contribution is given by
a simple Lorentzian. Applying the microscopic theory, the Fano features of the
total response can be attributed to the phase-sensitive superposition of the intersubband
transitions and the ponderomotive contribution. These results are in excellent
agreement with recent experiments.

text: 'The recently developed two-dimensional Fourier-Transform-Spectroscopy (2DFTS)
in the optical regime has been established as an elegant experiment, which has
manifold of applications in the investigation of semiconductor nanostructures.
Here we focus on the real and imaginary part 2DFT spectra. As predicted recently,
using rephasing and non-rephasing modes, we are able to determine the homogeneous
and inhomogeneous broadenings of coupled excitonic resonances even for weak disorder
where photon-echo data are not useful. Computed real and imaginary parts of the
2DFTS for rephasing and non-rephasing modes are compared with experimental data
of a GaAs quantum well. It is demonstrated, that phase sensitive data for the
rephasing and non-rephasing modes are able to accurately provide the disorder
induced broadening in a complex coupled system for each transition separately. '

text: "A microscopic analysis of the emitted radiation of a semiconductor nanostructure
after excitation with an extremely intense ultrashort laser pulse is presented.
It is shown that the extreme nonlinear optical response is not sufficiently described
by pure interband transitions but one has to include intraband effects as well.\r\nNumerical
solutions of extended Bloch equations that include the coupled inter- and intraband
dynamics are presented. For large excitation intensities, the intraband effects
strongly modify the polarization dynamics and lead to a strong enhancement of
high-harmonic generation compared to pure interband dynamics."

text: The band structure and wave functions of GaAs quantum wells are computed via
k.p band structure theory including anisotropy and spin splitting. Using these
results, the process of generating photocurrents by optical excitation is analyzed.
Depending on the symmetry of the material, the direction of the laser beam, and
the polarization direction of the light field/s, one can coherently generate charge
and/or spin photocurrents on ultrashort time scales. The direction, the strength,
and the dynamics of these photocurrents are computed and discussed.
