Giant Seebeck effect in Ge-doped SnSe
Thermoelectric materials may contribute in the near future as new alternative sources of sustainable energy. Unprecedented thermoelectric properties in p-type SnSe single crystals have been recently reported, accompanied by extremely low thermal conductivity in polycrystalline samples. In order to enhance thermoelectric efficiency through proper tuning of this material we report a full structur...
متن کاملPressure Effect of Seebeck Coefficient for Zinc Doped Tin Clathrates
We measured the temperature dependence of electrical resistance (R) and thermopower (S) of Cs8Zn4Sn42 under high pressure up to 1.2 GPa. Both R and |S| at room temperature increased with pressure. We observed gap widening, irreversible |S| increasing under high pressure, which were similar to the behaviors of Cs8Sn44. However, the relaxation effect of R for Cs8Zn4Sn42 was negligible in contrast...
متن کاملGiant electro-optic effect in Ge/SiGe coupled quantum wells
Silicon-based photonics is now considered as the photonic platform for the next generation of on-chip communications. However, the development of compact and low power consumption optical modulators is still challenging. Here we report a giant electro-optic effect in Ge/SiGe coupled quantum wells. This promising effect is based on an anomalous quantum-confined Stark effect due to the separate c...
متن کاملAntiferromagnetic Spin Seebeck Effect.
We report on the observation of the spin Seebeck effect in antiferromagnetic MnF_{2}. A device scale on-chip heater is deposited on a bilayer of MnF_{2} (110) (30 nm)/Pt (4 nm) grown by molecular beam epitaxy on a MgF_{2} (110) substrate. Using Pt as a spin detector layer, it is possible to measure the thermally generated spin current from MnF_{2} through the inverse spin Hall effect. The low ...
متن کاملStructural and Thermal Properties of Iron Doped SnSe Nanoparticles
-Iron doped Tin Selenide nanoparticles have been prepared by aqueous solution method in double distilled water at room temperature. All the chemicals used for this were of Analytical Reagent grade and of 99.999 % purity. Structural confirmation and particle size estimation of prepared SnSeFe0.5 Nanoparticles had been reported from Xray diffractogram obtained by CuKα radiation of wavelength 1.54...
