The thermoelectric properties of ReSi_(1.73+x)Al_(0.02) (-0.02 < x < 0.04) have been investigated in the temperature range between 323 and 1073 K. As a result of Al-addition, the electrical properties of the ternary at low temperatures are changed from the character of nondegenerate ...
BiCuSeO oxyselenides are promising thermoelectric materials, yet further thermoelectric figure of merit ZT improvement is largely limited by the inferior electrical transport properties. The established literature on these materials shows only one power factor maximum upon carrier concentration optimization, wh...
To make direct compari- sons with literature,37 compositions with x ¼ 0.03–0.04 were focused on in this study and Na doping was used to tune the carrier concentration for high-thermoelectric performance over the entire temperature range. Detailed synthesis and measurements on transport properties...
The crystallite size (DW-H) and lattice strain (ԑ) of the prepared samples were calculated using the Williamson-Hall equation [24].(1)βcosθ=4εsinθ+kλDW−Hwhere, DW-H is the crystallite size, K is the shape factor, ԑ denotes the lattice strain, λ is the wavelength of ...
The voltages generated from piezoelectric materials or thermoelectric materials can also be used for pressure sensors and temperature sensors, respectively. OFET-Based Chemical Sensors and Biosensors Sensor applications of OFETs for detecting chemical and biological species have received great attention, ...
It is also important to keep in mind that pyroelectric materials are classified as piezoelectric. Despite being pyroelectric, novel materials such as boron gallium nitride and boron aluminum nitride have zero piezoelectric response for strain along the c-axis at certain compositions, which is quite pe...
strain hardeningthermoelectric propertiesPolycrystalline niobium monocarbide specimens exhibit pronounced strain strengthening during plastic deformation above their tough-to-brittle transition temperature, which becomes more marked with increase in the amount of carbon vacancies in the niobium monocarbide lattice....
