摘要: In this Letter a new model for the band structure of n-Sn is proposed which compatible with experimental results reported on material and particularly measurements magnetoresistance pressure dependence conductivity (o) Hall coefficient (R) have been in relatively poor agreement models previously suggested. Theoretical calculations Herman, ' Liu Bassani, predict lowest conduction to be at center Brillouin zone I', (I', single group representation) symmetry, highest valence + (I"»' symmetry. This measurements' near 77 K oscillatory data' below 4'K, both show no measurable anisotropy. However, several unrelated require presence conduction-band minima (111) Magnetoresistance 200 by
