Journal ArticleDOI
Enhanced gas sensing by individual SnO2 nanowires and nanobelts functionalized with Pd catalyst particles.
TL;DR: Pd-functionalized nanostructures exhibited a dramatic improvement in sensitivity toward oxygen and hydrogen due to the enhanced catalytic dissociation of the molecular adsorbate on the Pd nanoparticle surfaces and the subsequent diffusion of the resultant atomic species to the oxide surface.
Journal ArticleDOI
Thermal conductivity reduction and thermoelectric figure of merit increase by embedding nanoparticles in crystalline semiconductors.
Woochul Kim,Joshua M. O. Zide,Arthur C. Gossard,Dmitri O. Klenov,Susanne Stemmer,Ali Shakouri,Arun Majumdar,Arun Majumdar +7 more
TL;DR: Using In0.53Ga0.47As containing ErAs nanoparticles, thermal conductivity reduction is demonstrated by almost a factor of 2 below the alloy limit and a corresponding increase in the thermoelectric figure of merit is demonstrated.
Journal ArticleDOI
Quantitative atomic resolution scanning transmission electron microscopy.
TL;DR: It is shown that intensity variations can be placed on an absolute scale by normalizing the measured image intensities to the incident beam using fractional intensity images of a SrTiO3 single crystal for regions of different thickness up to 120 nm.
Journal ArticleDOI
Comparison of methods to quantify interface trap densities at dielectric/III-V semiconductor interfaces
TL;DR: In this paper, trap densities at high-permittivity (k) dielectric/III-V semiconductor interfaces and their distribution in the semiconductor band gap are compared.
Journal ArticleDOI
Epitaxial SrTiO3 films with electron mobilities exceeding 30,000 cm2 V−1 s−1
Junwoo Son,Pouya Moetakef,Bharat Jalan,Oliver Bierwagen,Nicholas J. Wright,Roman Engel-Herbert,Susanne Stemmer +6 more
TL;DR: Control doping of epitaxial SrTiO(3) layers grown by MBE is demonstrated, which allows for low defect densities and precise control over doping concentrations and location and electron mobilities in these films exceed those of single crystals.
