Enhancement of Thermoelectric Efficiency by Uniaxial Tensile Stress in n-type GaAs Nanowires [PDF]

, 2011
The thermoelectric power-factor (PF) and efficiency (ZT) of GaAs nanowires (NWs) can be improved by (i) choosing a proper wire growth and channel orientation, (ii) by applying uniaxial tensile stress, and (iii) suitable wire cross-section size.

Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Thermoelectric generator fabricated via laser-induced forward transfer

, 2013
We show a novel method for the fabrication of a thermoelectric generator with the rapid, lithography-less technique of laser-induced forward transfer (LIFT), performed under ambient conditions.

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Chiral Phonon–Driven Ultrafast Spin Currents in a Non‐Magnetic Ferroelectric

Advanced Materials, EarlyView.
Broadband terahertz emission spectroscopy shows signatures of ultrafast spin‐current generation in non‐magnetic ferroelectric β$\beta$’‐In2Se3${\rm In}_2{\rm Se}_3$. Reversal of the emitted field upon sample inversion and substitution of Pt with W indicates spin‐Hall‐mediated charge conversion, while polarization‐resolved measurements reveal ...
