Resonant level-induced high thermoelectric response in indium-doped GeTe

Resonant levels are promising for high-performance single-phase thermoelectric materials. Recently, phase-change materials have attracted much attention for energy conversion applications. As the energetic position of resonant levels could be temperature dependent, searching for dopants in phase-change materials, which can introduce resonant levels in both low and high temperature phases, remai...

Resonant carrier scattering by core-shell nanoparticles for thermoelectric power factor enhancement

Formation mechanisms of spatially-directed zincblende gallium nitride nanocrystals Role of oxygen on microstructure and thermoelectric properties of silicon nanocomposites Spectrally and temporarily resolved luminescence study of short-range order in nanostructured amorphous ZrO2 Characterization of luminescent silicon carbide nanocrystals prepared by reactive bonding and subsequent wet chemica...

High thermoelectric performance by resonant dopant indium in nanostructured SnTe.

From an environmental perspective, lead-free SnTe would be preferable for solid-state waste heat recovery if its thermoelectric figure-of-merit could be brought close to that of the lead-containing chalcogenides. In this work, we studied the thermoelectric properties of nanostructured SnTe with different dopants, and found indium-doped SnTe showed extraordinarily large Seebeck coefficients that...

Direct imaging of nanogap-mode plasmon-resonant fields.

We perform direct local-field imaging of a plasmon-resonant gold nanoparticle pair separated by a gap of several nanometers using a scattering-type near-field optical microscope with a sharp silicon tip of atomic force microscope. The sharp tip allows the access for the nanogap and the high spatial resolution. Our results provide experimental evidence that the nanogap structure produces an opti...
