Abstract
The effect of the spreading resistance on the bileg thermoelectric generator (TEG) performance was experimentally evaluated. In planar bileg-TEGs, the width ratio of the p- and n-type legs should be carefully selected to compensate for ...

Abstract
The performance of a thermoelectric (TE) generator consisting of GeSn wire is experimentally found to be higher than that of a TE generator fabricated by Si wire. The TE generators are developed in a cavity-free architecture, where the ...
We report on the behavior of an acoustic phonon spectral linewidth of bulk single-crystalline Si1− xGe x alloy with the x of 0.16, 0.32, and 0.45 in the phonon dispersion relation along the Γ–X ([00 q]) direction. ...

Abstract
We investigate Sn incorporation effects on the thermoelectrical characteristics of n-type Ge-rich Ge1−x−ySixSny layers (x ≈ 0.05−0.1, y ≈ 0.03) pseudomorphically grown on semi-insulating GaAs(001) substr...
