In thermoelectric, phase interface engineering proves effective in reducing the lattice thermal conductivity via interface scattering and amplifying the density-of-states effective mass by energy filtering. However, the indiscriminate introduction of phase interfaces inevitably leads to diminished carrier mobilit...
emerging as potential candidates to alleviate energy problems1,2. The conversion efficiency of thermoelectric devices can be judged by the figure of merit, defined asZT = (S2σ/κT)T, whereS, σ, κTandTare the Seebeck coefficient, the electrical conductivity, the total thermal conductivity,...

As the temperature rises to about 700 K, the electrical conductivity σ turns to increase due to the intrinsic excitation. With the addition of Ag and Sb, σ decreases greatly from 83.3 × 104 S/m to 11.2 × 104 S/m at room temperature. The subsequent Pb doping further reduces the σ ...
SnSe nanosheets were obtained from the SnSe ingot after Li-intercalation and following exfoliation [392,393,409], and then evenly distributed in the PEDOT:PSS matrix and affected the intrinsic conduction of the composites. In addition, the polar solvent treatment [410–412] applied to the prepared...
This unit, which should be regarded as the actual transducer, also ensures that the intrinsic load signals of the freely suspended cantilever bending beam itself are always effectively installed in the same way. In view of these points, problems specially applicable to this form of elastic element...
These two factors contribute to the low intrinsic thermal conductivity of MVB materials32,41. This manifests that these tellurides are intrinsically good thermoelectric materials, as has also been proved in their single-phase bulk materials42,43,44,45. It is very striking that these MVB ...
These issues make a full-scale computation of the whole set of thermoelectric parameters particularly attractive, while a calculation scheme of the electronic and phononic contributions to thermal conductivity remains yet challenging. In this work, we present a full-scale computation scheme based on ...
SnSe content increased and the energy gap decreased. This was primarily due to a decrease in the zero-bias RA product as the energy gap became smaller. The solid curves in FIGS. 8A through 8F were calculated using a model for self filtering detectors. Peak detectivities of these devices ...
