Journal ArticleDOI
Efficient light trapping in inverted nanopyramid thin crystalline silicon membranes for solar cell applications.
TL;DR: In this article, an inverted nanopyramid light-trapping scheme for thin-film crystalline silicon (c-Si) solar cells was proposed to enhance light absorption within the semiconductor absorber layer and reduce material usage.
Journal ArticleDOI
Thermoelectric and structural characterizations of individual electrodeposited bismuth telluride nanowires
TL;DR: In this article, the thermoelectric properties and crystal structure of individual electrodeposited bismuth telluride nanowires (NWs) were characterized using a microfabricated measurement device and transmission electron microscopy.
Journal ArticleDOI
Nanoscale thermal radiation between two gold surfaces
TL;DR: In this paper, the authors measured the thermal radiation between a microsphere and a substrate which were both coated with gold films and found that the radiative heat transfer between two gold surfaces was significantly enhanced at nanoscale gaps beyond the blackbody radiation limit due to the tunneling of non-resonant evanescent waves.
Journal ArticleDOI
Four-probe measurements of the in-plane thermoelectric properties of nanofilms
TL;DR: A through-substrate hole under the suspended microdevice allows for transmission electron microscopy characterization of the nanofilm sample assembled on the device, which enables one to correlate the measured thermoelectric properties with the crystal structures of thenanofilms.
Journal ArticleDOI
In-plane thermal conductivity of disordered layered WSe2 and (W)x(WSe2)y superlattice films
TL;DR: In this paper, the in-plane thermal conductivity results for WSe2 and W4(WSe2)10 films measured by using a suspended device are about 30 times higher than the cross-plane values because of the inplane ordered and crossplane disordered structures.
