Journal ArticleDOI
Size-Dependent Melting Properties of Small Tin Particles: Nanocalorimetric Measurements.
TL;DR: The latent heat of fusion for Sn particles formed by evaporation on inert substrate with radii ranging from 5 to 50 nm has been measured directly using a novel scanning nanocalorimeter and a particle-size-dependent reduction of $\ensuremath{\Delta}{H}_{m}$ has been observed.
Journal ArticleDOI
A new class of doped nanobulk high-figure-of-merit thermoelectrics by scalable bottom-up assembly
Rutvik J. Mehta,Yanliang Zhang,Chinnathambi Karthik,Binay Singh,Richard W. Siegel,Theodorian Borca-Tasciuc,Ganpati Ramanath +6 more
TL;DR: A new class of both p- and n-type bulk nanomaterials with room-temperature ZT as high as 1.1 is demonstrated using a combination of sub-atomic-per-cent doping and nanostructuring to address the challenge of obtaining thermoelectric materials with high figure of merit ZT in thin films.
Journal ArticleDOI
Al-doped zinc oxide nanocomposites with enhanced thermoelectric properties.
Priyanka Jood,Rutvik J. Mehta,Yanliang Zhang,Germanas Peleckis,Xiaolin Wang,Richard W. Siegel,Theo Borca-Tasciuc,Shi Xue Dou,Ganpati Ramanath +8 more
TL;DR: Al-containing ZnO nanocomposites are reported with up to a factor of 20 lower κ(L) than non-nanostructured ZNO, while retaining bulklike α and σ, and holds promise for engineering advanced oxide-based high-ZT thermoelectrics for applications.
Journal ArticleDOI
Bonding-induced thermal conductance enhancement at inorganic heterointerfaces using nanomolecular monolayers
Peter O'Brien,Sergei Shenogin,Jianxiun Liu,Philippe K. Chow,Danielle Laurencin,P. Hubert Mutin,Masashi Yamaguchi,Pawel Keblinski,Ganpati Ramanath +8 more
TL;DR: The use of a strongly bonding organic nanomolecular monolayer at model metal/dielectric interfaces is demonstrated to obtain up to a fourfold increase in the interfacial thermal conductance, to values as high as 430 MW m(-2) K(-1) in the copper-silica system.
Journal ArticleDOI
Thickness dependent electrical resistivity of ultrathin (<40 nm) Cu films
TL;DR: In this article, Namba's model that uses the measured surface roughness provides the best description of the resistivity-thickness behavior in sub-40-nm thick Cu films.
