The paper report results of magneto-thermoelectric properties the single crystal Bi1-xSbx nanowires in glass cover with different diameters prepared by Ulitovsky-Taylor method. We study the effect of nanowire dimensionality in the Bi1-xSbx, nanowires in se ...
Thermoelectric properties of Ni substituted (La) cobaltate compounds with perovskite structure have been investigated. For all the studied compounds the Seebeck coefficient is positive indicating predominant positive charge carriers. The electrical resisti ...
In previous research we have demonstrated a micro thermomechanical pyroelectric generator (mu TMPG) as an alternative to thermoelectric generators to harvest ambient heat energy. In such a device, a thermal mass oscillates between a hot and a cold side by ...
We theoretically study the photoluminescence properties of organic-based microcavities with vibronic progressions. We analyze the relaxation from the exciton reservoirs to the polariton anticrossing region; the presence of vibronic levels qualitatively enr ...
This paper presents the process development towards a new generation of nanostructured thermoelectric generators for power harvesting from small temperature gradients by using a combination of traditional silicon microfabrication techniques, electroplating ...
The optimization of powders preparation and consolidation process leads to the achievement of a high thermoelectric figure of merit (ZT=1.25 at 800°C) in an n-type silicon-germanium (SiGe) alloy hot pressed at low heating rate. It has been experimentally o ...
This is the first study of the effect of pressure on transition metal dichalcogenides (TMDs) intercalated by atoms that order magnetically. Co0.33NbS2 is a layered system where the intercalated Co atoms order antiferromagnetically at T-N = 26 K at ambient ...
We present the first thermoelectric measurements on pentacene field effect transistors. We report high values of the Seebeck coefficient at room temperature between 240 and 500 micro V/K depending on the dielectric surface treatment. These values are indep ...
Germanium based clathrate-I compounds are considered for their potential applications due to possible thermoelectric and optoelectronic properties. Clathrate compounds may be an alternative to well known thermoelectric materials at higher temperature. In t ...
The resistivity of a very high quality anatase TiO2 doped with 6% of Nb was measured from 300K down to 40 mK. No sign of superconductivity was detected. Instead, a minute quantity of cation vacancies resulted in a Kondo scattering. Measurements of thermo-e ...
