Anisotropy of the electron g-factor in the InSb conduction band
Vdovin A. V., Skok E. M., Uvarov E. I.
The anisotropic correction to the g-factor of free electrons in indium antimonide has been measured for the first time. Its maximum value, Ag = g(H || [ 100]) g(H I) [ 111 ]), is 0.090 ± 0.004 in a magnetic field Я = 9434 G. It thus becomes possible to determine the matrix element representing the interaction of the valence band (V) with the upper conduction band (C')> which lies 3.5 eV above the ordinary conduction band (C).
