Thermoelectric efficiency at maximum power in low-dimensional systems
Natthapon Nakpathomkun, Hongqi Q. Xu, Heiner Linke
Low-dimensional electronic systems in thermoelectrics have the potential to achieve high thermal-to-electric energy conversion efficiency. A key measure of performance is the effic…
Valley-dependent Brewster angles and Goos-Hanchen effect in strained graphene
Zhenhua Wu, F. Zhai, F. M. Peeters +2
We demonstrate theoretically how local strains in graphene can be tailored to generate a valley polarized current. By suitable engineering of local strain profiles, we find that el…
Strain in Semiconductor Core-Shell Nanowires
Johan Grönqvist, Niels Søndergaard, Fredrik Boxberg +3
We compute strain distributions in core-shell nanowires of zinc blende structure. We use both continuum elasticity theory and an atomistic model, and consider both finite and infin…
