text: Transient changes of the optical response of WS2 monolayers are studied by
femtosecond broadband pump–probe spectroscopy. Time-dependent absorption spectra
are analyzed by tracking the line width broadening, bleaching, and energy shift
of the main exciton resonance as a function of time delay after the excitation.
Two main sources for the pump-induced changes of the optical response are identified.
Specifically, we find an interplay between modifications induced by many-body
interactions from photoexcited carriers and by the subsequent transfer of the
excitation to the phonon system followed by cooling of the material through the
heat transfer to the substrate.

text: Hydrothermal method enables to synthesize high quality piezoelectric materials.
To shorten the reaction time and to get higher quality materials, we propose an
ultrasonic irradiation to the solution during the hydrothermal method. We named
it ultrasonic assisted hydrothermal method (UAHTM). We have synthesized lead-free
piezoelectric material and PZT thin film and the effect of UAHTM have been confirmed.
In this study, we tried to improve UAHTM. First, to generate powerful and stable
ultrasonic irradiation at high temperature on UAHTM, we developed a new transducer
using LiNbO3 single crystal. Second, to prevent contamination to the materials,
A Teflon cover on the tip of transducer was attached.

text: Uniform mesoporous Si double layers are formed on 4 inch p-type < 100> wafers
with an off orientation of 6º towards < 111> by means of electrochemical etching
in ethanoic-based HF electrolytes. These substrates are of interest for the epitaxial
growth of III–V compound semiconductor stacks on their top for the production
of multi-junction solar cells and very thin electronic devices. We demonstrate
transfer of porous layers after an annealing process in hydrogen atmosphere. Electron
Back-Scatter Diffraction analysis confirms that the substrate orientation is conserved
during the etching and annealing steps. Confocal μ-Raman spectroscopy analysis
shows a decrease in the Raman signal intensity after etching and a subsequent
increase after annealing while no shift is observed. By means of Atomic Force
Microscopy, analysis the surface appearance after the etching and annealing steps
can be visualized. The mean surface roughness varies during the process from 0.55
nm for the unprocessed wafers to 0.27 nm after etching and 0.78 nm after annealing.
The decrease of average roughness after etching is caused by an electropolishing
step prior to porous formation. Despite of slight increase of mean surface roughness
after annealing the samples are still appropriate for high quality epitaxial growth
and subsequent lift-off.

text: The hydrothermal method enables the production of high-quality piezoelectric
materials. In this study, we propose to irradiate the reaction solutions with
ultrasonic power during the hydrothermal method to obtain a shorter reaction time
and a smooth film surface. A high-pressure reaction container for the ultrasonic
transducer was newly developed, and the ultrasonically-assisted hydrothermal method
was examined by using this container. The effect of ultrasonic assist on the synthesis
of lead-zirconate-titanate (PZT) thin films and (K,Na)NbO$_{3}$ powders was verified.
Thicker PZT film, thickness around 10 ${\mu}$m, could be obtained in one process,
and (K,Na)NbO$_{3}$ powder was synthesized in half the previous reaction time.
