Extracting band structure characteristics of GaSb/InAs core-shell nanowires from thermoelectric properties
Nanowires with a GaSb core and an InAs shell (and the inverted structure) are interesting for studies of electron-hole hybridization and interaction effects due to the bulk broken band-gap alignment at the material interface. We have used eight-band k·p theory together with the envelope function approximation to calculate the band structure of such nanowires. For a fixed core radius, as a function
